How full to fill Tank

[lost in the bush]

Hello

Other than having fuel spill out of the tank, how full do you fill the tanks.

We filled up Big Momma yesterday. Was not sure where to stop, so I topped off at about 1/2" below the top of the screen?

Is this correct?

I fill mine till I run out pf money. That is way below a full 50 gallons!
On a long road trip I shake the deuce just to get in all I can!

OK will do. Thought that since only one Indianapolis in the USA would be enough..

Will do.. Where is the town "Central" in NY?

Funny stuff.. Wasn't bad Diesel was $3.22 per gallon and GL left almost a full tank.. USe to big fuel bills . Our armored Suburban has a 49 gall on tank and only gets 4-5 mpg.

At least he has the state! It is hard to help people or meet them if you don't know how close you are to them.

We will be looking for room between the frames for a large fuel bladder with skid plate to protect it from road trash.

There are 3 cities named Indianapolis in the US. Indianapolis, Indiana is in Marion County. Indianapolis, Iowa is in Mahaska County. And last but not least, Indianapolis, Oklahoma is in Custer County

I am within the rules with that location.

OK'y Doky did not know, the location part of the my account had " preferred" next to location which left me with the idea it was an option. It is done.

I do put all I can on road trips. If will be setting it will be an inch or two below the top. Your fuel cap is not vented so excess fuel will make its way to the venting system where it does not need to be.

OK thanks so I would be better off leaving 2-3 inches below the top of the screen?

There should be a line. If not I would paint one about 4 inches down. Diesel here is still up around $3.80 so save every drop. I do not have a line on my concrete pump and I just bring it to the bottom of the filler neck, 2" down form the cap. It splashes out even with the cap on, but I dont worry about it, because I aint paying for it

Depends on what I am doing. If the M814 is gonna sit for a while, I leave 2" of head space. If I am on the road, then I fill it to the vent hole on the screen support.

Military doctrine was to leave headspace since the vehicles were topped off when brought back into the Motor Pool. Most units painted a line where the proper headspace position is.

I have seen drivers fill the vehicles to the brim and then when the tank heated up the fuel would leak out on the ground and all ell would break loose.

Another reason not to overfill is that in some cases the vent line for the fuel tank and brakes are interconnected. Overfilling could push diesel fuel into the master cylinder. I believe there was a work order to separate the brake vent and fuel tank vent but on my truck it was never done. I had to separate them myself.

Also, keeping the tank full helps reduce the risk of condensation.

If you're going to be going down the road right away, you can fill it almost to the top. Level will drop quick enough that you won't have to worry about overfilling
If it's going to be parked, especially in the sun, leave a couple of inches at the top of the tank.
