Gas tank fill filter????

[31 Model A]

Those that use a filter basket that sits down inside, I found since it restricts the fill flow, the pump backflow kicks off the pump easy and often, how do you get around this without just removing the filter all together? Takes forever to fill with it in.

[Nabco]

I don't seem to have that problem, I leave it in and it fills up just fine.....one thing though is I probably am not putting the filler novel all the way in, I'm holding it up a little.

that should do it and only pull the pump handle to the first click (slower fill)

[captndan]

Waste of time take it out. The dirt and rust are already in the tank. The pump gas is already filtered.

It's not a filter. It's a fire prevention and explosion screen that is supposed to act as a wick in the event of combustion. Remove at your own risk.

There is a gas tank neck extension advertised in the back of the Restorer every issue that helps with this issue.

Always keep a depends around the fill neck opening in case you spill any

Take your time! It is not a contest to see how fast you can put 10 gallons in your tank. Wayne

Great point Ray, I guess it would of been helpfull info to mention I use one of the gas tank neck extensions too....sorry Ed

Found it, use that extension when filling in conjunction with the screen installed?

[Nabco]

Yes

[31 Model A]

Ordered....

Thanks to all............

[Redbird]

It is a spark arrester.

you can go to Home Depot and buy an 1.5" PVC reducer for .50 that will do the same thing.
Just place it in the neck, turn on the nozzle and go. I have used one for over 10 years with no problems.

Is this an insulator for static spark?

[sphanna]

I am wondering about the possibility of static electricity risk with the PVC reducer. I am not one if the experts here, so am not criticizing your procedure. Just wondering.

[Fullraceflathead]

I don't have a problem with the original one.
I noticed the repro's don't have near as many holes though.

[Glenn C.]

The spark arrester will not prevent a fire at the nozzle of the tank, but it will prevent a tank explosion due to vapors above the fuel. Hopefully all fueling nozzles and hoses have been fabricated properly with a imbedded grounding wire within the hose which grounds everything from nozzle back to pump of delivery.

[TerryH]

Many, many Model A owners do not have that screen in place, and haven't for a very long time. I have yet to hear of a documented case of an explosion taking place due its absence. I've had two Model A's over the years, and neither ever had one, and I also use a PVC extension which works great filling the tank.

I've never heard of one either. I'm not one who is against safety regulations, but it does make one wonder if it was some government bureaucrat in 1927 who thought there might be a problem, someday, somewhere. On the other hand, Henry had the best engineers, accountants, and lawyers of the day, and the risk may have been measured and the decision made in Ford's office.

Meanwhile, I have 'em in my cars.

[mshmodela]

I like the idea of having the screen --if for no other reason of keep things out of the tank...it cannot hurt to use it... Like all things model A, the pace of fun is the 1920's and 1930's so fueling slower goes with the territory

as someone stated earlier I wonder if the fuel lines didnt have built in ground wires or other means to ground the car while filling so static buildup was a much more prevalent thing.

its one of those parts that i feel if ol henry thought it could be done without he would have to same money and time.

[DougVieyra]

Besides the 'Fire Arrestor' use, I use my 'Filter Screen' to aid the tank baffles in their anti-sloshing of the gasoline on quick turns, when the tank is full. Yes, it is a little hassle to pull it out every time I fill up, but as I fill up only once every a month, I find it a useful part of the original gas tank engineering and have left it in place, as intended by the manufacturer.

I have found that the PVC 'Filler Riser' does work to help get a maximum amount of fuel into the tank with minimum hassle. I need two specific sizes: the '28-'29 tank is different than the '30-'31 tank. And size matters.

If you're PARANOID about static electricity, I wonder if those ground straps that drag under the car are still available???

[George Miller]

Do newer cars have spark arresters?

Always wondered about those things as a kid. Why do you need to have a rubber strap dragging on the ground when you got 4 rubber tires on the ground ?

Yo' Brother Phil,
Those straps have metal threads in them. Originally designed to get rid of STATIC electricity from NYLON seat covers, those zaps would cringe your BUTT & bulge your EYEBALLS
Bill Shocking

[JD 1931]

Installed a new one but got rid of it the first time I added gas ,would only fill half tank then nozzle would shut off....

[CarlG]

Mine does not have one. Every time I try to fill a friend's car that has one, I feel the #@*% words coming out.

if you look closely alot of fuel tankers have a strap that drags on the ground still.

[barnstuf]

In the time frame when the Model A was new gas pumps were more primitive and not all had their hoses grounded. As to the subject of filling your tank I can fill easily at most gas stations in my area as most have vapor recovery nozzles. In particular I have yet to find a Mobil station where I can not fill easily. There is one Gulf station in my area where it clicks off after just a bit of gas. I avoid that station.;

[mike657894]

nearly all road motorcycles have steel tanks and none of them come with a screen.

[MikeK]

Just to clarify things a bit, there is a difference between a "spark arrester", which the Model A DOES NOT have, and a "Flame arrester" which is the function of the heavy perf'ed metal fill tube.

The body of any vehicle (or aircraft) can develop a static potential relative to ground. Even if the fuel hose and nozzle have their own embedded ground you can still get a spark. The safe procedure is to touch the nozzle to the metal of the vehicle before removing the filler cap. Metal to metal contact must be maintained while filling. Use of any non-conductive filler extension is not a safe procedure.

Flame arrestor: This is actually a heat sink. The metal must have sufficient mass and small enough holes so that any flame (burning mix of fuel and air) will be cooled to below the sustained self-ignition temperature before it can pass all the way through the holes. Vapor external to the tank ignited by a static spark cannot pass a flame front through the flame arrestor to the vapor inside the tank.

Motorcycles and other small tanks: If the tank volume is small and the filler opening large any ignition of the internal vapor will simply produce a scary 'pop' without damage to the tank because the pressure never reaches the tank burst point. In a larger tank ignited vapors will produce a pressure that cannot vent fast enough through the filler to prevent catastrophic tank rupture. A full tank is very safe, not much vapor volume. An empty tank (full of vapor/air mix) is dangerous!

Modern cars: Most all have a small metal spring flap just inside the hole that only fits the evil E10 nozzle. When that flap is closed you have an effective flame arrestor. When you insert the nozzle, it first touches the filler tube metal thus grounding the vehicle to the nozzle. The nozzle then pushes the flap open as you seat it into position. Only then do you start the flow.

I'll keep my stock Henry flame arrestors in position.

[Rancho Deluxe]

They were also used made out of Brass in the Model A..

It arrived today, installed it for fit, it fits loose, is this normal? I have a 31 and bought a 30-31 neck extension.

Ed, I have a 30, also bought mine from Snyder....it should actually fit into place like the gas cap, drop it in and give it a little turn to lock it in place.

It won't lock, it will turn to the notches but it's loose to fit.

Just went out and checked how mine fits when I turn it and it locks into place I can't pull it out without turning it again.....it is not a tight fit like the cap it still moves around a little.....not tight in place....hope that helps

Yes, tight fit is defeating it's purpose is the words from Andrew Jackman. Always good to be sure. Just called him. Now next trip out, I'll get to test it and have one more frustration leave me......I don't have many.

Used it twice today and it worked perfect, problem solved, thanks for the tip.

[captndan]

Just ask any aircraft owner why his plane is grounded to the fuel truck.
I remember seeing trucks using a chain instead of a strap. In low light you could see sparks going to ground.
