question on fuel line quick disconnects

Hey guys , i need to disconnect the fuel lines from my sending unit and have noticed from looking at different threads that alot of people had a hard time with the quick disconnects. i just have an old metal fuel line disconnect tool in the tool box which i believe is 5/16 on one end and 3/8 on the other. will that work or is there other ones that are better( plastic, etc..). Thanks for any input

I just used the disconnect tool when I did my pump, worked fine. But I think I swore 3x before I started for good measure.

I've used everything from the plastic tool purpose-made to a small screwdriver. My difficulty was never to get the QDs apart, but to get them to seal on a vacuum (fuel line).

Quick shot of WD-40 or similar makes both connecting and disconnecting much easier. For that matter, any disconnect tool operates better in a knurled connection with some lubricant.

thanks for the great advice, I will just need to remove them as I plan on eliminating the quick disconnects

Makes you wonder why they call them “quick.”

I removed all of the quick connects on the fuel system, at least on the suction side. (of course I didnt tighten the compression fitting when doing the hutch mod, so had to go back in.) I like not having the quick connects much better. Especially having had to disconnect twice.

No kidding. I've found that they require every bit of brute strength you can muster, in about 15 attempts, to get apart – when they suddenly part and you knock your own teeth out with your hand when they release.

Is there ANYTHING on these trucks that doesn't require a 15,000 ft-lb impact wrench, sledgehammer, oxy-acetylene rosebud and plasma cutter to disassemble? Opening the glove box, maybe?

Wellllll, my truck is kind of a "special needs" truck, since it came from the Salt Belt and apparently didn't have the salt rinsed out underneath EVEN ONCE IN 15 YEARS ... but I wish you luck!
