Stupid Question

Ok for a while now I have been running into a problem every once and a while.
my truck (1973 F-250 HB 360) would fall on its face like it ran out of gas, I thought this might have been a vapor lock issue so i pulled all the fuel line away from hot spots but it is still happning. today I took a few minutes and looked under the hood and found the supply line (to Carb) fitting was real loose not leaking but very loose, i put a wrench on it and one turn it started to leak...

Is it possible this could have been my problem??

Sorry for the long read

Brian

The fuel filter may be clogged. Try a new fuel filter.

Already tried that, I was just wondering if anyone thought the loose fitting could be cause for "falling on its face" thing.

Thanks for the reply

I would go let it sit and run it and see if it still does it since you fixed what you think the problem might be. But if the issue still arises maybe it could be sediments in your gas tank plugging the hole for gas or possibly a carb issue.

I would think that if the loose fitting was before the pump, then it would suck air, after the pump, it shouldn't have any effect if not leaking under pressure.
I would check the rubber line between the tank and the frame. These sometimes dryrot and won't leak fuel, but will allow air to be sucked in.

My truck does a lot of "falling on its' face" when it's losing the fuel pump. I've got through three of them in less than a year...

Proper Title of Thread.

Leaking Fuel filter at carb

I suggest someone has turned it on so tight it cracked and leaks with more torque.

Suggestion: Replace with another.

Please title threads with the actual topic in them.
