I tried searching but couldn't quite find an answer, so here we go.
I'm replacing my gas tank, fuel pump, and rear fuel lines up to the filter on my '93 RCSB 5.7L. I ordered all the parts and have them here at my house, but the truck is at my parents' farm. Needed something to tinker with while quarantining (just came back to Canada).
I ordered a stainless hard line set with braided hoses from Lines to Go. This kit: 1993 Chevy truck fuel lines for K Series 4WD Gas Reg Cab 6.5ft box5.7L. Stainless Steel
And I ordered this AC Delco sending unit from Rock Auto: ACDELCO MU2429 Gold / Professional; Includes Sender
The return line (5/16) fits fine, but the supply line does not want to screw onto the sender fitting. The tread only barely catches then doesn't want to screw on more. It feels like it's hitting metal first, vs the other line where I can feel it hit the rubber O-ring first.
Is it possible that the flare isn't proper on the sending unit? I don't want to try reefing down it yet for fear of stripping threads or something.
