Small fuel leak at fuel filter fitting
I replaced the fuel filter on my 64 L76 (365HP). After reconnecting the fitting to the new filter and connecting the hose from the filter to the carb, I pumped the gas pedal to see if gas was injecting into the carb. It did, so I then started the car. I then noticed a slight leak from the 90 degree fitting on the outlet side of the gas filter (GF-90). I was able to make on more revolution around to tighten the fitting, but it still leaked a small amount. With two 90 degree fittings going into the filter, how can you make sure the fittings are tight and still have the 90 degree fitting for the rubber hose from the filter to the carb point in the direction of the carb? If can tighten this fitting anymore, it will position the outlet tube for the rubber hose away from the carb. Do I need to resort to using a teflon paste to help seal the fitting? Thanks.

Depending on the condition of your fittings, a bit of Teflon tape may help.

Nothing wrong with using the tape that I know of. You can also try backing the 90* fittings off a half turn and then re-tighten, they may seal then.

If that 90 degree fitting is chrome plated........that is your problem. Been there....done that. I went to NAPA, and got a fitting without the chrome, and it solved the problem.

there is also an aircraft item called a 'flare saver' that might work. i use them on my fuel lines that leak a bit.

I use just a tad of teflon tape quite often...just be sure not to wrap it so far forward that any of it blocks the fuel passage.

That's probably why the OEM GM fuel fitting threads and the flare end of the tube (that I know of) were devoid of chrome.
