Default Fuel line leak on generator

I have a fuel line leak on my return fuel line from the injectors back to the tank (top line in pic). It's coming from where the flex line attaches. I've tried tightening it but don't want to break it or strip the thread. Is there a part # for the flex line, or will I need to take it to a shop to match it up or have one made?
As a temporary fix, there's stuff called "magic tape" that you wrap around pipes. It sets hard & is meant to be waterproof & fuel proof. I don't want to take the fuel line off, then run into additional problems & have no generator while in the desert here.
Any advice appreciated!

Not really sure what you have but looks like metal line hooking to pipe coupling and flex line hooking to other side. So both fittings are going into pipe coupling and would use thread sealer. Adapter fitting between coupler and flexible side is probably jic fitting with no sealer. If it’s the hose it looks like weatherhead hose and truck repair or hydraulic hose repair people could probably make new one. Not sure where it’s leaking on you. I’ve used rescue tape on fuel return line on vw diesel. Worked well.

The silver fitting is reusable and the fuel line is available from NAPA or any good parts house or truck stop.


The fitting unscrews off the flexable line as it is a 2 part fitting.
When reassembling be sure to cut the ends square and add a little grease to the male fitting before working it into the fuel line and then tighten the back nut to it.

Rescue tape didn't stop the leak, probably due to the fact that I couldn't really get at the junction & stretch the tape while applying it, plus diesel fuel all over, dripping too fast to clean it up & apply tape.

So here's my question: Does the electric fuel pump stay energised even when the genny is powered off? Diesel is dripping constantly from the line. Today, I disconnected the genny battery for 4 1/2 hours...still dripping. I know I need a new fuel line, it's seeping out between the fitting & the flex line, but out here in the boonies, I can't get one, so I need a temporary fix to minimize the leak till I'm back in civilization.

Also, O'Reilly said they custom make flex hydraulic cables; would that work on a fuel line?

hydraulic hose will work. Got a pair of vice grips? Clamp the leaking line shut.

Thanks for the advice, Rick. I'm a bit cautious about squishing the braided cable line in case a; it breaks (it seems really stiff & brittle) or b; it won't open again after being clamped shut. Either scenario would mean no generator power, & we're planning to stay another week or so in the Quartzsite desert. But it's great to know hydraulic will work; soon as we get back to shore power availability, I'll take the pipe into O'Reilly to get a duplicate made.
One other question: could I use regular fuel line, attached to the union with a Jubilee type hose clamp?

Parker auto parts in Parker has hydraulic and fuel hose, I’m sure you could also find it in Blythe

If they are jic connectors on the ends, I have a few sizes to plug or cap the fittings when you take the hose off. To catch up with me, just look for Murphy.
