rubber fuel lines

anybody running rubber fuel lines on a 2wd 350,
what is the best route to run them from the pump to the carb?
pics would be great
p.s. i have an edelbrock carb with a dual fuel line kit that drops the inlet on the left front of the intake about an inch up.

Re: rubber fuel lines

That might happen too. I'm with Longhorn man. I don't like them. Rubber lines belong running along the frame IF anywhere

Re: rubber fuel lines

I have to say that I've run these for a LONG time on a LOT of engines with no issues.

I agree that hardlines should be run whenever possible, but I don't see the risk in this application.

Re: rubber fuel lines

i used to run a hard line but for no reason at all replaced it with rubber. i zip tied it to the heater hose coming out the left of the water pump, behind my ac bracket, and zip tied to the heater hose outlet on the manifold. then i have a glass filter and hose to the carb. it sounds very dangerous, but hasn't given me a problem yet in a year and about 8000 miles

Re: rubber fuel lines

For what its worth, I use rubber fuel lines on my stockcar...I have them running inside a 1" square metal pipe that goes from the trunk to the engine compartment. You might find someway to run that along the frame then cram your lines through it.

Re: rubber fuel lines

Rubber fuel lines are made to carry well over the 6-7 PSI your mechanical pump puts out.

Re: rubber fuel lines

I have never had any problems with rubber fuel lines either. Use hoses that are designed to carry fuel and are not subject to heat problems since the hoses are made to tolerate the heat. I have a similar setup as pictured except my fuel filter is below the water pump, that way if a leak develops at the fuel filter (clamp failure) the fuel leaks on the ground not on the hot engine.

Re: rubber fuel lines

sounds like going down the road that fuel leak would spray right back on your hot exhaust KABOOM

Re: rubber fuel lines

Never ever had a problem with rubber hose in streetcars, race boats, or circle burners. Route it properly, secure it properly and you won’t have a problem. If any one has had a rubber hose failure it was not the hoses fault it was the installer.

Re: rubber fuel lines

The installation manual for the Edelbrock 1406 states specifically to use rubber fuel line. Even if you ran hard line all the way to the last inch and then connected it with rubber you still have the same possibility(which is very little) of a fuel leak on top of your engine.

Just do as stated above. Use rubber line that is designed specifically for fuel, be smart in the way you run the hose, and every oil change check to make sure your clamps are still tight. All should be ok. But this is just my $.02, use your own discretion.

Re: rubber fuel lines

[QUOTE=Moneypit;2306129]The installation manual for the Edelbrock 1406 states specifically to use rubber fuel line.

thats strange because the installation instructions that i have under parts required it reccomends using edelbrock #8134 chrome steel fuel line and in thier pictures in the owners manual show only using about a 2inch piece of rubber tubing// oh well i guess he got a different translation than i did

maybe if you could list exactly what page of the manual reccomends using the rubber hose from the pump to the carb i could look it up easier THANKS

Re: rubber fuel lines

I run mine mine just like "mathufham"('s), but I run it through a length of heater hose to help insulate it.

You can by a barbed fitting that will screw right into the fuel pump.
