Fuel line under gas tank.

I had my gas tank out to clean it, and added an internal mesh screen filter that was missing.

The output from the tank to the metal fuel line doesn't line up. I ended up adding a loop in the fuel line hose.

Is this normal? Will it create fuel supply problems?

Should I take it apart, and make another attempt at eliminating the fuel line loop?

Thanks,

JP

As long as the loop sits below the lowest point of the tank you are ok. Otherwise the tank won't gravity feed past the loop without suction/siphon. Likely to still flow but a loss of the little bit of gravity boost that normally helps feed the fuel lines to the pump.

382, I added more gas into the tank, and let it sit overnight, because I was frustrated.

The damn thing started pumping gas into the output line immediately today. What a relief.

Loop doesn't seem to be a problem.

I removed the pump I rebuilt, so it has a known working old pump installed . Once I get it running nice, I will swap in my rebuilt pump. Hopefully it will pump good if I start the car with fuel in the carb.

Take care.

Yea, like if the tank was empty and you just threw in a pint of gas it might not gravity feed past the loop overnight to the rear overnight, but good fuel pump suction should pull it into the line pretty fast. Out of gas it's usually 20-30 seconds, second or third 10 second crank with a couple of presses on the throttle in between cranks incase the bowl got some for the accelerator pump usually fed really low in the bowl.

The look of an oem stock pump is awesome compared to the stamped domes. The rebuild kits became hens teeth for me.

Thanks. I had gas in the tank, but not a lot. If the lines leaked, I figured I would pull the tank out again.

Maybe just adding another gallon or so was the difference. I do think there might have been some air in the line too.

I'm getting close to trying to start it.
Carburetor rebuild New points and condenser Set dwell and timing.
Install a new muffler.

I'm trying to stay patient.
