Fuel Pump Connections

[67GMC]

The Fuel Pump in my 88 was connected to the fuel lines with hose and hose clamps on the metal tube. There's male threaded fittings on these but I cannot seem to source a female connector so I can make a proper hard connection. I have mostly older vehicles with mechanical pumps so not sure how to connect to this. I can do what the PO did and use hose clamps again but I've got a new fuel tank so want to fix it up a little better.

Any advise appreciated. They look like 3/8 NPT and 5/16 NPT but that's not quite correct. Maybe metric flare threads? Part source would be great.

The other side of those is the sending unit. Sounds like the PO hacked it up.

They're metric o-ring fittings, probably M18 or M16. They're supposed to have a rubber hose with that style female fitting on them, hence the rubber hose and clamps.

Damnit it I was looking at the picture wrong. You need fuel lines.

Sorry for hijacking your thread 67GMC. I'm just in the businees of replacing all 4 of my lines. I know Earl' have a adapter fitting(like 8 bucks each) for both pressure and return so you can use an4 and an6 . As you can see on SAATR rockauto pic thats almost 100 bucks per line for oem,thats at least 400! There have to be a less expensive option. I was thinking using earls adapters and braided hoses instead of lines,any thoughts on that?

Yes-That's the problem. The OEM style is very expensive and really, it should just be a flex line like the brake line flex hoses. I thought if I got a female M14 then I could hook that up to a hose barb connector.

Thanks-I thought that was it but I couldn't believe the price. Just need the fitting so I can do a half-a$$ job!
