Return Fuel Line Perished

[Guest craig030774]

i fitted rubber fuel hose and a return when i built the car it is the proper stuff as well, however yesterday struck it up for the first time in about 6 months and had fuel leaking all over from the return.

 

1 do i need a return as using bike carbs and a seperator with mechanical pump

2 . if i run a stainless return what route as dont fancy taking tunnel sides out had a quick thought about running through side rails or maybe underneath

 

what are your thoughts. oh and it is a 2b

[Guest craig030774]

so has everyone run fuel lines through tunnel

Yep, through the tunnel but with 8mm copper microbore tube.

No you don't need a return line, throw the seperator away but you will need a pressure regulator from the mech pump otherwise the pressure will be too high.

Both my fuel lines are copper and they both run inside down through the passenger side outer floor edge, i will only use rubber pipe as a straight joiner now due to the bend perrishing problems i have had in the past, my return pipe is only used as a tank breather.

I am not a great believer in routeing fuel pipes down the tunnel where there are moving parts that could go wrong.

I don't know if my friend used new lines but I had to replace his as they had leaked last week and it's only about 2 years old.

 

On mine I used copper down the tunnel and flexible Unleaded stamped hosing on the bendy / flex bits. No problems as yet.

I'm nervous about my fuel lines down the tunnel in case of prop failure and keep meaning to re-route them. I'd route them elsewhere if you can.
