Default Fuel Pump Connectors

Pulled my fuel pump for a swap and some of the plastic quick connectors(04-08 style)had been damaged. Does anybody know how to find them in-store? Is it logical to just refit with hose fittings? I seem to only be coming up with male/male universal splices....

Mostly just need to find the fuel pump connection sizes... Im guessing 5/16” for fuel filter and 2 small ports on the fuel pump, but there is a size up from that with a single connector (3/8?) and another much larger at about 9/16 maybe. Anyone know the exact sizes?

So I found all of the connectors but one that measures 9/16 diameter. No store online or brick & mortar seems to have this. It’s definitely 9/16 (possibly 5/8) with a 90 degree angle. How do these not exist?

I ended up finding the connectors at Napa and had a PITA getting the things on the fuel lines. I had to replace almost every single connector on the fuel pump and the opposite ends of the lines since they pretty much all broke. Ill look for the boxes and see what sizes I had. I know there were a few different sizes and a couple 90 degree ends as well. It can be done, it just happens to be time consuming.

I couldn’t find the boxes, but found the leftover connectors. Sizes are measured by the smallest inside diameter in the connectors; hose-ends are measured by smallest outside diameter. Note that these are “quick connectors”. I do not recall how many of each, but they come in packs of 2 or more so count yours first and maybe leave room for a spare one in case you break one putting it on. I had to use heat to get mine on; obviously do this while they aren’t connected to the truck. Pressing them on is the correct way, but without a tool for that, heat works. Good luck

I think if/when I get to this point in maintenance, I'll ditch the quick connects and replace them with some sort of conventional coupling. Who needs that extra problem. Cars have been running and maintained very well for a hundred years with the "convenience" of "quick-connect" fuel couplings.

the same thought crossed my mind. I figured if i couldnt find the correct connectors I would go this route.
