130S fuel line

[Speedster]

Hi need a bit of help. Rebuilding late 73 car and fuel line very poor. Is it best to replace in copper or rubber? Difficult to feed down the tunnel but is that correct route? At same time putting Facet pump in boot so electric system.

I put my fuel line inside the carusing solid fuel line its a plus 2S 130/5 I bought from Merlin Motor sports at castle Combe. make sure that what ever you use is OK for Ethonal that starting t be aded to fuel these days

Yes the gas line goes down the tunnel. When I replace mine it will be zinc coated steel tubing. Some of the guys go thru the rear bulk head then thru the cabin and out the front bulk head. Can be nicely done with tubing bender to hug in tight to the corners on the floor running along side of the tunnel.

The original nylon type factory fuel line is a fire waiting to happen..........it's old.

Thanks guys for your help

Speedster,
one more thing. If you are positioning the electric fuel pump in the trunk, that is all the more reason to go with new material as you would be pressurizing the fuel line where is was once just passing thru and being drawn up with the original pump.

We just got in a car that that has an electric fuel pump in the trunk and some knucklehead grounded another item to the pump body housing. People.........never cease to amaze me...sadly they never seem to cease

Thanks Fourth Gear as putting in complete new fuel line and separate supply and earth for pump.

Having all the metal components in a fuel system at the same (ground) potential is good practice. Grounding the metal pump body in a fiberglass car is a good idea even if the pump motor has a separate ground wire.

If it was a boat "big brother" would make you do it.

Thanks guys for all the help.

Don't want to hijack but I think Speedster is sorted.
I am also fitting a Facet fuel pump in the trunk, but I need to know where the best place is to fit it.
When I bought the car, there was no floor or back panel, only a spare wheel from some other car!
I have renewed the bracket /shelf beneath the tank for the floor but If someone also has some dimensions / distances regards the back panel, and where it fits, that would be great.
Thanks,
Kev.

As there wasn't a pump there originally it really a case of wherever fits best for you pump and connections.

I suggest fitting it to the boot floor (body not boarding) or back of the boot between the spare wheel and battery. Given the tank connection is on right side of the car in front of the battery this location make the most sense for routing of fuel lines.

You also need to find a switched live to control the a relay for the pump power. I think some people use the input to the fuel guage sender but this is a feed from the voltage stabilizer so I'd try to avoid using it.
