MG TD TF 1500 - Union / sleeve to join fuel line

A club member mounted the fuel line backwards in his TF-1500 restoration (pump in rear). The "pump" fitting is in the engine compartment and the carb flex hose fitting is at the pump. He doesn't want to struggle to remove the line and reverse it.

A possible solution may be to cut off the fittings along with a few inches of fuel line, then reattach to the correct ends of the line. Do you know if a copper union / sleeve is available that could be sweat-soldered to join the pieces? What size? Source?

Another solution may be to unsolder the fittings from the line. Then reattach to the correct ends of the line. Is that possible / easy?

A third solution may be to use an adapter on each fitting. But that may be a future source of leaks. Source?

Which solution is easier/better ... cut the line, remove the fittings, or use two adapters?

I have a similar question for my TF681 (firewall mounted pump). A previous owner cut the fuel line near the carb to insert a fuel filter. He cut the line about four inches from the fitting that connects the carb flex line. I want to eliminate the filter and rejoin the two fuel line pieces into one.

Thanks for your help,

Oops - wrong description of the cut fuel line on TF681. The line was cut before the fuel pump. Not at the flex hose. Either way, I want to eliminate the filter and join the two copper line sections.

Years ago, new TF fuel line had the wrong under bonnet fitting. I used propane torch, unsoldered and switched to the old fitting. So if new line fittings just soldered, you should be able to do that. Shouldn’t be that hard to remove the line and switch it around? No idea if a sleeve exists to join cuts. And yes, every fitting is a potential leak. George

I am with George. Pulling the fuel line should be trivial, especially if you can put the car on a rack. This is one of those things you will forever kick yourself in not doing IMHO.

The hard part will be to straighten the bends on one end and then putting the correct bend on the other. I would suggest some sort of flexible rodding to make sure the line does not crimp.

Suggestion how to remove the inline filter: Buy EFI fuel line. It is super tough and high quality. And two EFI fuel line clamps that have rounded rather than sharp edges. That would be a repair that would last years. If your filter is where I think it is, it would be pretty sketchy to solder under the bonnet with existing gasoline and wiring around, etc. You don't want to do a Jay Leno... George

Agree with George EFI fuel line and clamps are cheap, simple, and you are dealing with a minimal amount of suction at the inlet to the pump.

As for the incorrectly installed line, cut of the ends and join at correct end with EFI hose and clamps if not concurs. If concurs, remove the pipe and reverse it.

Of course, vendor could label I guess.

Like George, I had to remove the forward fitting from my original fuel line and solder it to the new line. The Moss fittings, at the time, wouldn't fit the original carb flex line. Easy job. PJ
