If the leak is in the steel line, you'll probably need to replace that. I think you'll have better access to the pump if you remove the alternator and vacuum pump. Allows you to work from the top. And 105 on asphalt means you're not gonna be laying out...good luck!

Replaced the pump, and I’m still hemorrhaging fuel which means I got to go after the steel line. My only hang up on the matter is that I’ve never done steel lines before and I’m not sure how to go about it. My plan was to fully remove it and take it to autozone where I can get a new one cut and hopefully bent into shape for me.

Try NAPA, fuel pump kit Belknap. I think there are ready made out there. Or you can fab a new one, but that will require a flairing tools and benders. I think there are other replacement options. Have a wrecking yard handy?

Didn’t see anything from Napa on a fuel pump kit that would work, and my luck with junkyards is not good. For something like this I’d rather fab a new line than hope that one I got from the yard is good. This truck is my daily and I don’t really have anything else to get around in so I can’t order one since it needs to be finished today. I do appreciate the links and the help though

if you can replace the pump, you can make a new line
most auto parts stores carry bender and flaring kits
watch a youtube vid on how to
practice on a few pieces and then do it, steel line is fairly cheap
bring in old line to match fittings if you need them

If you have a NAPA store near you call them before you give up on them. If you have an old established store even better. They will have come across this situation before. You can't always rely in the on line stuff.

Got the leak fixed. New pump, new line, lots of gasket maker.
Even with the new line it was still shooting out of the fitting real bad even though it was all new. Decided to put fuel resistant gasket maker on the pipe below and above the fitting. Let it sit for an hour and a half before testing it and found no drops. Revved up to 2500 while parked and no issues. Hopefully this is now fixed for a while at least, thanks for the help on the matter

I had to use the new one if I wanted to put it on at all. I couldn’t find the inverse fitting for the top end so I had to cut my old one and put the old fitting and oring on the new one. Bent it all to hell because idk what I’m doing but it’s on and it’s not leaking so I’m happy. Still not sure if I got the arm of the pump in right but I did my best to slide it under the cam. Would that be noticeable right away? The only thing I’ve had is stalling from no fuel initially

You mentioned you couldn't find the correct flare fitting. Did you use a flaring tool to put an inverted flare on the new fuel line?

I had the flare tool and the bending tool, so I cut the end off the old one and took the inverse fitting for the fuel filter side of it off the old pipe along with its oring and put them on the new one then flared it afterwards

Which type of flaring tool did you use?

Inverted flares will be easier to make if you're using nickel-copper fuel line.
