Default 1991 Fuel Line ( where to buy ? )

I replaced my 1991 Jimmy fuel tank and fuel pump / sender.

Out of the fuel pump is a M16x1.5 male nut with an o-ring at the end of the fuel pipe.

That attaches to a flexible stainless steel braided line with a female M16x1.5 fitting.

After buttoning everything up nice and tight, there is a leak between the stainless braided line and the rigid metal line that goes up the frame to the fuel filter ( also M16x1.5 female )

Did GMC / Chevy drop everything M16x1.5 on newer models ?

I can't find a direct replacement fuel line at any of the local dealers or at LMC Trucks.

What style fittings do the newer fuel injected trucks use ?

Any suggestions ? I will hit a few wrecking yards next week.

autozone help isle maybe?

when i did the fuel pump on my 1990 pick up truck a few years ago i remember replacing everything from the filter back to the tank and got everything from autozone, just going to have to buy random line and flare it or compression fitting it all together.

though i dont remember having or replacing any stainless lines back there.
