Gas tank question Hey guys, I am still trying to crank my 47 after it has sat for about 4 or 5 years. I found out I was getting no gas to the fuel pump. I have disconnected everything and blown air through the gas lines, elec fuel pump and into the gas tank. I took the sender unit out to have a look inside. Now, question, does the line going into the tank have a filter on it that might be stopped. The tank doesn’t look all that bad from what I can see but it looks like it wouldn’t be a big job to drop the tank and either replace or put some of that stuff in it to redo the inside. Any thoughts on this. Thanks

Re: Gas tank question Why drop the tank when that may not be the problem...I would check the electric fuel pump if its getting power to it..then go from there..

Re: Gas tank question No filter on the inside of the tank unless it has been modified. Start at the outlet of the fuel pump, disconnect the output line and see if it will pump fuel into a catch container. Then work your way forward to the carb and see where the fuel stops.

Re: Gas tank question If you have any flex line from the tank to the electric pump, make sure it it good. Possibly blocked.

Re: Gas tank question is the inlet filter of the electric pump clear? if it has the very small metal filter it could be clogged

Re: Gas tank question Kelly. You had it running but it was bucking. Did you get that problem fixed? Is this a problem that has developed since you got the bucking fixed? Need any help? Lemee know. Lawson

Re: Gas tank question I once had a problem where I was driving to a V-8 meet and my '48 started bucking and died. It started after sitting for a bit and got to where I was headed. On the way home it did it again and I was lucky one of my friends was trailering his car home. We put my car on his trailer and I drove his home. I took the tank down and discovered the fuel tank liner that I'd put in it years earlier had come off and was plugging the outlet in the tank. I took it to a radiator shop where it was cleaned out. I've never had that problem again.

Re: Gas tank question I read an article that says the ethanol type gas will cause the sealer put in tanks to eventually turn to goo and clog up fuel systems. Anyone had problems with this ?

Re: Gas tank question Blow air into the line from the tank with fuel pump
disconnected. blow air in from bottom of tank WITH CAP REMOVED. G.M. |
Re: Gas tank question The line inside the tank that runs down the side and along the bottom of the tank could be rusted out (usually along the bend going up the side)

Re: Gas tank question On my 36 tank the inlet tube that is inside of the gas tank had plugged up so much that I’d only be able to drive a few miles before I’d be on the side of the road. I bought a new Drake tank and installed it.
With the original tank on the bench I found that I couldn’t get much air down the inlet tube and I couldn’t push a 1/8th inch rod through it. I ran a long drill down the pickup tube to clean out the crud that had accumulated. Don’t know if it was an accumulation of rust, gas tank sealer or a combination of all of the above. Whatever it was was very hard to drill out. I doubt that you could diagnose this problem without removing the tank. John |
Re: Gas tank question Had the same problem with I liner I installed years ago. The rad shop at the time only seen it a couple of times. It was due to ethanol. The newer sealers are ok

Re: Gas tank question Install your pump as close to the tank as possible. Pump instructions will tell you.

Kelly. I had a fuel problem with my '46 Coupe, and found a wonderful surprise when I removed the fuel sender from my tank. The previous owner had used red rubber for a gasket, and a bunch of it deteriorated and fell into the tank. The pieces caused a restriction in the fuel pickup line in the bottom of the tank. Assuming your '47 is similar, lift the floor liner in the trunk, remove the cover that is held in place by one screw, and that exposes the fuel sender. Disconnect the sender wire and isolate it with tape (don't want any sparks if you turn the key on). Remove the sender, and look over to the left at the bottom of the tank, and you will see the fuel pickup tube. That was where a piece of rubber was stuck in my case.
