Filter install

[Gooseloony]

Have been having troubles with carb., cleaned it twice. First time car fired right up--2 days later wouldn't start; cleaned it again and installed inline filter between sediment bowl and carb, fired right up, ran for 5 minutes or so then started to starve for gas, then died. Now won't start, it has gas in the tank and the new filter appears clear. I did receive the pencil filter I ordered a few days ago, should I try installing it or is it possibly a bad carb? Any ideas and if I do install the pencil filter inside the tank, can anyone recommend a means and method (photos are very helpful). Thank you, Nick

Hey Nick,
Question first...have you ever had your tank cleaned/inspected for rust ?
What I'd try to see first, is if tank rust IS clogging up system. take a line (rubber hose) and run it down into a large container. Open the fuel petcock at tank and drain fuel to see what comes out. If rust , you have a decision to either clean tank thoroughly, or to install a 'dirty leg' (or whatever it's called) to catch all debris and empty it regularly until all rust particles are trapped / removed.
Do you have the brass wire filter installed up inside of tank ? This will help also, if you want some help in filtering what is coming from tank (suppliers have this scheen).
Now when you drain tank contents into a large container, you will get a good idea where you stand as far as how rusty stuff is coming from tank. An inline filter will only catch so much stuff before needing replacement.
I also place very strong large magnet beside outlet of tank, for insurance, even tho my tank has been cleaned.

Oh, and DO NOT push gas line in tooo far into carb inlet as this will create problem which will be fuel starving symptoms.

Remove the gas cap and see if the car runs. You may have the vent hole in the gas cap plugged off. 30-31 repo gas caps with a single rivet in the center are notorious for rotating the vent hole out of position and plugging it off.

Tom I will try that (forgot to mention my car is a '28 if that matters?). And Hardtimes, thanks for explaining the process, something tells me I may have to do as you suggested. I would've thought the filter I put in would have taken care of any sediment issues to the carb.

[Y-Blockhead]

You didn't mention, are you getting any debris in the sediment bowl? Any water?

Yes sediment in bowl...

[Y-Blockhead]

I seem to remember a thread a while back about using a electric fuel pump and a large filter and chase tail (pump the gas out the bottom and back into the filler). I think it was Tom that suggested that, could be wrong.

[Y-Blockhead]

I forgot to mention, if you have the glass sediment bowl, a Wix #33039 filter fits in it. I'll have to double check the number, it's a filter for a '77 Cadillac or something crazy like that.

[JBill]

I've had the filter that fits in the glass bowl clog up with very fine sediment very quickly, with the result that you describe. I just took it out and have had no problems.

1. evaluate the severity of the situation by looking in the tank if need be flush it
2. Get rid of your inline style filter as some of them impede the gravity flow plus they're ugly.
if you cut your line to install it buy a new one, and make sure the line does not extend more than 1/8 past the ferrules on both ends or it will restrict the flow
3. Install the pencil filter in the tank
4. install a sediment bulb filter change as necessary but if this one continues to clog the dirty leg will help. as always the best way is to restore or replace the tank.

i run the filter even though i dont have a problem with crap ,,its just good insurance

What a gorgeous looking engine Mitch. I assume the exhaust manifold is ceramic. Did you paint the extension to the muffler?

thanks Bud
pictured above
i high temp powder coated the manifold and entire muffler assy it has held up excellent

on lucy i used the ceramic manifold and hi temp powder coated the muffler black
this one is just completed so well see how it holds up

Thank you guys. Mitch would you have any suggestions on installing the pencil filter? I'm not much of a mechanic, are there any tricks of the trade, the instruction says it just pushes in but then it says shims may be needed etc, also do the threads need any retreatment with anything while reinstalling? I'm confused, any photos would also be helpful. Thanks for everyone's help. Sorry photo came out sideways.

[Mitch//pa]

its been my experience of all the pencil filters i installed were a perfect fit into the valve. nothing else was needed..
i use liquid teflon on the valve threads never had a leak..
i usually put a 1/4 " fuel hose on the end of the line at the carb and drain the tank out into a gas can
keep a container handy in the car to catch any extra fuel when removing the valve or undoing the inside line

[Gooseloony]

I guess what confuses me is that it looks like a short nipple between valve and tank, where does that filter go in at that point. Does it get pushed up into the tank and then the nipple goes in, then the valve? I'm still confused.

[Mitch//pa]

remove the valve and it installs on the threaded end. look at the other thread Tom posted on the cut away filters. that shows it pretty clear from the view inside the tank
the screen goes into the hole on this pic

[Gooseloony]

Oh think I see now (gotta tell you, photos work wonders for me). Just to recap---so remove the valve, put the filter into the top of the valve and screw the valve back in? So that's not a nipple between tank and valve?
Thank you very much Mitch

[Mitch//pa]

u got it
the threads that screw into the tank are part of the valve

[Tim Armstrong]

I had a fuel problem with my A. It would run a few feet and stop. Worked on everything, then I removed the in line plastic fuel filter. That fixed it.

[Mitch//pa]

i happen to be doing one today here is a pic the filter base just needs to be pushed in a little further. its a very tight fit

[Purdy Swoft]

I use the filter like Mitch shows above . I consider this filter a must !!!

[Tom Wesenberg]

I also use and keep a spare pencil filter on hand, just in case I have to work on a car without one already installed. They are cheap insurance.

For motorcycles and small engines I use the brass screen from automatic tranny filters, which I can't easily find, now that I'm not working at the dealership or junk yard. Anyway, all you have to do is cut a square of the fine mesh brass screen, then roll it up just tight enough to fit the gas tank fitting, then fold over the top of the screen.

[Purdy Swoft]

Back in the day before the stand up filters were offered. an older guy showed me how to insert a short piece of tubing in the cutoff valve to keep the loose rust and varnish in the bottom of the tank from entering the cut off valve . . Magnets placed on the bottom of the tank near the cut off valve will attract loose rust and may help . We haven't mentioned cow magnets for a while . Smiley face .

[Gooseloony]

Just finished installing the pencil filter, will be putting in the sediment bowl filter in after returning to the auto store, cleaning the carb again and trying to fire this thing up. Note: before installing filter in tank I drained the gas into a container with shirt material over it--never saw any sediment on top of shirt, seems a little strange because it was in the sediment bowl before I began.

[Tom Wesenberg]

You need to rock the car side to side as it quickly drains from the tank. This will stir up the fine stuff and help it drain out.

Oh I did some shakin

[Purdy Swoft]

Usually the rust doesn't come out untill the last little bit of gas drains. The in line filters used in modern cars are suppose to be used with a fuel pump and are too restrictive for gravity flow . You can actually have too many filters in some cases with gravity flow systems like the model A. There also have been micro filters offered by some for model A's. The micro filters are so fine that small particles that really wouldn't cause any problems will stop them up completely. I would avoid any micro filter on my model A, I had nothing but problems. There are many choices, some will always disagree. I just say live and learn .

Update: so after draining the fuel tank, taking the carburetor apart and cleaning, installing a pencil filter inside tank, putting filter in sediment bowl and replacing bowl to carb fuel line, I fired it up HOORAY (knock on wood). Drove 12 mile round trip to DMV to finish registration, all without a hitch! I'd never driven the thing further than around the block. And I did all of this myself (as you all already figured out I am no mechanic---so I surprised myself). Thank you are your input and suggestions--but don't go away yet...there's more to come!

[Mitch//pa]

thanks for the update glad it all worked out nice
you did a fine job

Thanks for the update ! A lot of problems are stated with efforts to help given from afar, and no feedback. When guys give feedback , positive or negative, it helps.

Do they not filter fuel before delivery in the States? It sounds like you guys have persistant problem with crud in tanks.

[bikejunk]

it really isnt the fuel its the 84 year old tanks ,and the new gas that has 10% alcohol that causes all new problems by dissolving crud .

In the 60's when I worked at the Standard station all pump hoses had a final filter right at the handle. About every couple weeks we had to change the filter because the fuel flow started to slow from junk in the filter.

[johnbuckley]

Ah, yes. I'd forgotten about your Ethanol 10%. Some but not all of our fuels here have 5% ethanol; some have none and some have 10% . So to some extent we can pick and choose.

[George Miller]

Another thing that makes sludge is running a car to cold. Growing up in mich, we use to see a lot of that type of sludge. They use to run cars 160 in the summer and maybe 180 or maybe 160 in the winter. That along with short trips and non detergent oil. will make lots of sludge. I have seen Ford Y blocks through push rods from so much sludge.

[diomed]

My daily driver is a 2005 Kia. It only has a sock filter on the pump inside the tank. No real filter anywhere else. Apparently this is common in newer cars. The fuel is filtered as it comes out of the gas station pumps, so I guess they figure another filter on the car is redundant . I've never had any fuel issues, so it must be 85 year old fuel tanks and not the gas station.
