Fuel line won't seal.....

[Onehit]

I ordered a pump to carb SS fuel line from inline tube. I'm having trouble getting it to seal at the pump. I called their help desk and pretty much was told to twerk it with an deep socket, also to seat it and loosen it a bunch of times for the flair to seat and keep trying till it seats. The old line seals just fine but the nuts are striped. Any suggestions..

Have you looked at the flare to see if it was formed properly. If it's not there should be some uneven pressure marks if it not formed properly.

Look closely. Is it leaking around the threads or around the tubing?
may just need some Teflon tape around threads

Both sides of the flair look the same to my nothing odd.

its leaking around the tube not the thread, is it ok to use Teflon on the fuel lines?

 

[airboatgreg]

Yes. Sometimes the flare on aftermarket stuff isn't as good and Teflon tape on the threads will tighten it up for lack of better wording. A couple rounds on the threads and hopefully you will be good to go

Gas will destroy the Teflon tape. Ask me how I know...

That's one of the problems with stainless lines is there is very little room for adjustment and because their hardness they don't conform well if not perfectly lined up.

Might also inspect the seat on the pump or pump fitting, just to rule it out.

I tweeked it the best I could it pretty much falls in to place but still the flair just won't seal its clearly coming from between the tube and the nut not the thread. I have a new fuel pump I never installed I'm gonna try that tomorrow and if it still leaks then we'll see how their customer service is.

what about cutting off that flair and make a new one...
