filling tank

[gogi]

i am anal about filling my gas tanks on all my vehicles i find filling the venture to be very time consuming to fill all the way to top is there a secondary vent on the tank that may be clogged it leaves at least 1/2 gallon to be filled when it first hits the filler neck as it goes down soooooo slowly?

When the gas hits the bottom of the filler neck the tank is full.

That little bit that you get by filling the neck to the top and then watching it slowly go down is filling in some of the air space that is designed into the tank. If you were to fill it all of the way up it would dump some of the gas on the ground as the cool gas heats up and expands.

 

There are some people that punch holes around the top of the filler neck so that they can fill every last drop. but you can only do that IF you going out for a long ride. If you fill it and let it sit, it will just leak out.

Go to the bathroom-drink your gatoraide and then fill your tank with the vent holes in the filler neck. The. Reverse will give back the 1/2 gallon you just squeezed in
