Hi guys,

Just a-wondering. Do the fuel lines (high pressure injection BTW) have to be soild, or can you get away with using flexible ones?

I have some copper tubing (central heating microbore) that I want to use, but I was wondering if rubber tubing might be more suitable?

Cheers,

Sam.

Hi, use the copper pipe every time, rubber (and it has to be rubber fuel injection hose not just fuel pipe) should only be used when absolutely necessary, i.e. to join the ends of the copper to filters etc in very short lengths. Rubber also tends to perish after a yr or 2 so really needs to be accessible to check regularly.

Cheers Drury, that's what i needed to know.

Glad I'm not the only one who had to get up early today. (in work for 5am, with the clocks changing it was more like 4am!)

problem with over braiding is that you cannot see when the rubber is perrished!:eek: so could leak, then catch fire??

I am using mostly copper, but i ended up kinking the tubing too much while bending it to fit in the rear section, so have just used flexible in the rear till i get to the transmission tunnel.
