Fuel line

[jack350]

The too and return lines on my 350i are copper with injection hose either end to make the connections. Is this original or should it be hose all the way?

[jindle]

that's original

[mrzigazaga]

Same here...

Injection hose all the way, 350i built in 1986....
That is TVRs for us, all different.
All replaced a couple of years back.
Next time will go for as much metal as possible.
Will still keep it in the tunnel, as don't like it in one of the sills as many have, too vulnerable for me.

My old 350 had rubber hose and I changed it for copper. My 400 also has rubber, but it runs between the outrigger and the sill, well away from the exhaust. On the 350 the pipes ran up the centre of the car.

My original rubber ones ran up the tunnel but due to their age and all the joints in them I replaced with new high pressure rubber, I was amazed just 4 years later how the heat had set the rubber to the route it took so I took the decision to replace again in high pressure rubber but via the offside sill route and up inside the wheel archprotected by a plate. Thing is now everyone is going on about methanol and its effects on rubber the story probably continues. Wooly.

According to 'Classics Monthly' this month, ethanol is also corrosive to copper. So whether your fuel lines are rubber or copper there is still a problem.

What about some nice stainless steel? Bling!

I'm redoing mine on the chim at the moment, it only had r6 on before which all perished.
8mm copper pipe down the chassis, soldered on the 8mm couplers so the hose has something to grip on.
Then R9 hose in the engine back and to pump etc.
Here is some info on the different ratings - beware of some stainless braided which uses the cheaper r6 hose

I have Aeroquip and metal .. with a flashy joint to connect the two.
