Rubber fuel pipe throughout ???

Someone refresh my memory please.

Can I use rubber fuel hose all the way through the tranny tunnel or does it have to be copper for the majority of it's length?

Cheers,

Pat...

Don't know about SVA, but IMHO, best to use copper as much as possible.

Does this mean you've got your chassis woes sorted then?

Agree with Steve - whilst there's no actual rule IIRC - the rubber stuff just flexes far too much (especially with injection)

I know copper is a ball ache - but it's definitely better IMHO...

In a fashion.

Will update at the end of the week.

Using copper will mean having to have a connection from the engine to a rubber pipe to the copper pipe, then at the back from the copper pipe to a rubber pipe to a step down bit and then another rubber pipe and then the fuel pump.

Using rubber throughout would go right from the engine to the step down bit meaning two less connections.

My tunnel is fully enclosed so don't see why not and can't find anything in the manual.

you've got the copper, and olives are only 20p each to give reliable joints. you can than use 5/16" p clips, to save having to get some bigger ones.

according to the lads on the rhocar forum, rubber pipe leaks petrol vapour, so you car will always smell of petrol too. don't know how much truth is in it, but copper definitely doesn't.
you know it makes sense!

I was considering doing this too. Maybe better to go 8mm braided right though.

It seems I remember a warning about copper pipe fatiguing and breaking over a period of time. My suggestion would be steel pipe for the tunnel and braided for the pipe to engine. If you want to save a bit use rubber for the pipe to the tank though I'm using braided.

either will do; rubber hose is fine; it is not inside the car per se so should not cause fumes leaking; dunno if that is true

there was some discussion not too long ago about copper tubing being bad for injectors - you'll need to search - but given the amount of miles our cars do, I woldn;t be conerned.

My piping was fitted - rubber hose - but I'd use copper if I were doing it.

You can flare the ends in brake pipe fashion or compression glands so there won't be leaks.

Hello,

I used flex rubber all the way, but in the tunnel i put it in a pvc pipe so its not flexing so much.

Just like others say no extra connections to look after.
