MG TD TF 1500 - Fuel line recommendations?
|The TF chassis is done and ready to be put back together. I have all new brake lines ready for installation, but my question is, what should I use for a new fuel line from the tank to the engine bay? Copper or steel? It had copper which is easy to work with, but I'll use what ever is recommended. Also, shouldn't there be rubber connecting lines on each side of the rear mounted fuel pump? This car didn't have any, just direct hard lines to the pump. PJ|

|Copper is the easiest to use, and it polishes up nice in the engine bay,,,, steel will rust over time,,,|
I did however have a refusal when I went to register mine here in CT. They would not allow copper lines until I could prove that it was originally done thqt way,,
|the pump is hard plumbed. The fuel line is your return for the electrical sending unit (actually, the power goes to the bulb, then the ground goes to the sending unit which completes the ground via the fuel line) so if you want a fuel level light, you need to either ground the sending unit body to the chassis or have a hard connection at the fuel pump.|

You can get soft copper tubing of the right diameter from a local plumbing supply house. Specifically, it is 5/16" refrigeration tube and is usually sold in 50 foot lengths, but you may be able to buy it by the foot.
Assuming the correct fittings are still on your car, you can reuse those fittings and solder them on the new copper tubing. Some advantages of making your own fuel line are that you can fine-tune the length to exactly match what you need and you will have plenty of extra tubing (for less money than Moss, too) in case you make a mistake.
|Are the fittings still available....want to add a second line and have the copper tubing.....|
Abingdon Spares carried them a couple of years ago...probably still do.
|"you need to either ground the sending unit body to the chassis or have a hard connection at the fuel pump."|
There is a ground wire that connects directly to the fuel pump. That said, it is a good idea to run an additional ground wire to the tank in some way.
Gordon - The fitting you are looking for are carried by Moss. See Fig. 11 in the chart, Fuel Line Fittings in the SU Fuel Pump Articles section of my web site. Cheers - Dave
|I would suggest you check the highway code for your state/province etc.|
Here in Qubec, copper brake lines are no longer allowed. Steel only. I know from bitter experience.
My daughter's GAN3 ('65 midget), was rejected at inspection with completely new copper brake lines. Not a happy camper!!

We're talking about the fuel line, not the brake lines.
|Back to your second question PJ, yes, there should be a rubber pad on either side of the fuel pump mounting plate. Cheers - Dave|
