Fuel Pump
I just installed a new Airtex fuel pump from Advance Auto and I can't stop a leak in the fittings going up to the carb. Beginning to wonder if it is in the pump body.
I reused the old fittings, then replaced them with the new that were included included and it still leaks.
I will try a new line next.

I've used that yellow plumber's teflon tape with great success...NOT the white stuff.
It is best if you can get a seal without it, but the yellow tape does work.......has been many years and no leaks with it.
EDIT: I better explain a little more. I have found that sometimes a factory made flared fitting seals against the screw-in fitting, but not against the raised dimple inside the carb (or fuel pump in your case). I use the tape on the outside threads of the screw-in fitting.

John if I read that right ? Sounds to me like since both your old fittings and the new ones both leaked.. Sound like some bad machining in the port of the new fuel pump...

I picked up a new line last night. I will bend it and mount it to see if that is where the problem is.
I don't see any issues with the line but for $5.00 it's worth a try.

Oh-oh Russ....we are both named John....which one are you "talkikng" to?
In my case, it wasn't the pump, it was leaks at the carb. Due to using a fuel log form Summit that had flares formed in a press.....with sort of a parting line, I think.

After a 40 mile road trip to another store because the local didn't have another, I have the 2nd pump installed without a leak. Hot DAMN!
I am damn tired of gas in my face and down my arm.

I guess the big issue is that changing a pump should be straight forward bolt up exchange. It still leaking makes me want to drink some Sunoco 260.
Take it back and the guy tell you "I can have you one tomorrow" is another butt rub.
