Damn fuel line leak

[cmayna]

And it wasn't no small drip, rather a nice spewing. Minor leak is from the nylon inlet washer. I talked to Holley tech who said that I need to tighten down the inlet fitting (that pinches the nylon washer)pretty firmly but when I do the washer distorts and I don't think that is going to help.

The bigger leak is coming from the threads of the dual feed line fitting itself, as if the flared tubing end is not seated. I torqued the hell out of the nut but still no go. This is happening on both tubes.

I do remember when I first did a test fit of this Mr. Gasket POS, I didn't like the way the tubing was entering the carb fittings. Seemed almost at an angle.

Have ordered a Holley line from Summit and should get it tomorrow.

Oh well....On to other prior to fire up issues

That doesn't look too good there - is that the washer Holley provided? If so, it's pretty poor. IMO fuel fittings like that should use metal crush washers, not nylon.

When I rebuilt my 4160, I chased two leak issues like yours:
the original inets to the bowls leaked so I replaced both inlet fittings which came with very thin metal seals and it solved that leak.

the dual-inlet line to the bowl fittings leaked. The fittings on the inlet line and the carb bowl are flared; the carb inlet secondary line was not exactly entering the bowl straight and thus not seating the flares flush. I bought a Holley line and it leaked worse. I ended up putting a phillips screwdriver into the Summit line to straighten it out so it entered the bowl fitting straight to seat the flare. I also used teflon tape (johnpro tip) on the inlet line fittings and it solved the issue.

+1. On all the Holley's I've ever worked on have had a thin metal crush washer there not nylon. Never had a problem with them leaking.

Same issue I had, they ALL suck! Leaked like crazy.

Interesting - the one that came with my el cheapo Summit carb never leaked. The chrome quality is another matter - can you say "flaking off"? I knew you could.

I Teflon taped my inlet fittings too. No leaks ever.

Yeah those washers are Holleys # 26-102.

Put Teflon tape on the threads and move on to the next problem.

Makes me glad I went with the AN braided hose-type feed lines instead of the hard lines. My install was a snap!

This is similar to the one I went with http://cgi.ebay.com/ebaymotors/6-AN-6-FUEL-INLET-LINE-HOLLEY-DUAL-FEED-750-850-950_W0QQcmdZViewItemQQhashZitem27adf06388QQitemZ170421937032QQptZMotorsQ5fCarQ5fTruckQ5fPartsQ5fAccessories
