Fuel line rubber?

[Lou Earle]

I am repairing and re-doing fuel line on 48 plym with chevy 350 engine.

Is there any particular reason I should not just run a rubber line - besides expense from the gas tank to the fuel pump? On the one the guy before me had put in he has a rubber line from fuel pump to the rear spring area on passenger side. where he or I had messed up was running a steel line to the rubber line and it being to close to drive shaft and not properly supported. But why shouldn't I spice that rubber line to another rubber line and run it to the gas tank?

I can't see any reason why you couldn't. Steel would be more resistant to damage, but other than that, it should work. I have the Poly gas tank from Ply Do on my coupe. I have a rubber line coming off the tank pickup to a steel line. Then a rubber line coming from the steel line in front of the engine block to the fuel pump. So..........don't see why you can't splice those two lines together as long as they don't leak.

Earl, when I plumbed my carbs, I found some poly fule line on a spool at ACE hardware. It is stiff but flexable, and would be more resistant to the extra stuff in new fuels. Measure cut and clamp. Was less that 50 cents a foot.

I had some left so I replaced some suspect places of the original steel line, and also gave me the opportunity to put in a couple of in line filters in the linefrom the tank to the pump.

They also sell aluminum fuel line or some material like that in a easy to bend roll at vendors like summit

Since those harmful Mcdp(Dunno the initials) but harmful additives was removed and replaced with certain amount of ethanol and THAT eats pure rubber like a dog eats his doggie biscuits,,, you NEED ethanol resistant line AND then it may disentigrate too fast. Looks like the steel line would be more permanent,,,but the resistant rubber would 'work' least for a while. Till you saw that tell tale puddle under there. I 'think' mostly steel was used because of all the gravel roads and how many rocks get thrown up under there!! Still get those even on paved roads but not the volume!! At price of gas,,,hate to lose a tankful cause of a 'cut' line etc.(even tho it's rubber on the end!!)

Don, guess that's one advantage to the poly tank. If my gas line breaks I won't lose the whole tank, only what's in the line. The pickup tube on the poly tank is on top of the tank and has to be pumped out of the tank by the fuel pump.

I replaced the fuel line on my P15 this week end. It's not a hard job. Most of the fuel line runs along the left frame. I used a 5/16 steel line from JEG'S, comes with fittings. The line is flexible and easy to bend. I also used closing springs for wooden screen doors for armor where the line comes under the frame. Worked great. Took me about 4 hours and some beers.

I know it runs a little spendy but I have used fuel injection hose and it is some tough stuff----great for the small fuel line from the frame to the fuel pump on the sixes........

Just keep in mind that most fuel hose is not designed to be on the suction side of the pump, they were on the pressure side. The hoses used to supply the suction side of the pump tended to be heavily reinforced to keep them from collapsing.

Thanks for All the input. All things considered I went with steel lines with a in line filter in the line underneath the car between 2 sections of pipe. I had not thought about the suction and new gas issues. Thanks again you all put me on right track --again.
