the metal connetion between the fuel pump and the pressure side fuel line has a pesky slow drip. I cannot tighten the fitting any further. Any suggestions? (other than replacing the fuel line). 1951 chevy 216. Thank you
Take it loose, add some grease on the back side of the flare and a little on the threads, then retighten and see if that helps. If not, replace the line and start again.
More than likely you’ll have to replace the fitting and re-flare the line. The flare gets work hardened after taking it off and on over the years and no longer seals. You should have enough line to cut off just the end to remake a new flare. If not, you can replace the line with a pre made-up one from the vendors or just make up a new one. I used CuNi (copper/nickel) with a cheap HF bender and it came out great.

A new fuel line (if you are unable to bend one) AND new fittings at both the carburetor and fuel pump are MUCH cheaper than an engine fire!
The fuel line in Phil's pictures is quite easy to bend.

Good carburetion is fuelish hot air The most expensive carburetor is the wrong one you attempt to modify. If you truly believe "one size fits all," try walking a mile in your spouse's shoes! The Carburetor Shop
