Hi,

I apparently have a venting problem with my 94 F150 short bed. It just has one tank, but I have to put gas in very slowly or it just shuts the pump off.

Do I have to drop the tank to fix this? Also the gas mileage is about 9 mpg which seems low even for this truck. I have replaced the plugs, O2 sensor and had an overall tuneup. Would the venting problem effect fuel mileage?

Thanks.

Just giving this a bump.

Tried just pulling the pump out until it is barely in there?

Nothing new I haven't heard before with numerous vehicles.

Yes this does help, but shouldn't I fix this? If it is just effecting gas pumping it's not a big deal, but can this affect mpg somehow?

Depends on the pump too. There is a shell station in my home town and their pumps act like that on both my truck and my beater. You have to hold the nozzle a certain way and go slow at first. Its the only station I've been too that does this.

This happens at all pumps. Sometimes I can just barely let it trickle in.

It's a venting problem.

So do you have any advice on how to fix this problem? Does the tank have to be dropped? Thanks.

No you don't have to drop the tank. It's something with the filler neck. It's a hose in a hose, for venting.

Excellent thank you. That helps a lot.
