Gas Tank Quantity ?

I read in my Owner's Manual and in all the threads back on this site that B2's have 20+ gal gas tank. My new oldie '87 Eddie Bauer Automatic would certainly seem to have 12.5 or so. Is that right or have I got something else to fix?

Thanks!

Gas Tank Quantity ?

Funny you ask. I have an '86 that only holds 13 gallons max at fillup, and my husband's '90 with the same tank holds a lot more. It seems strange that they'd do this. Something is weird about the gauge. Someone once told me that they have 10 gallons after empty. Makes no sense to me and I'm not going to test it. I'm just tired of having to go to the gas station so much more. Let me know if you find anything else out. I need to fix mine, too. Angel (Gabbygal1972@home.com). Thanks!

Gas Tank Quantity ?

i read somewhere that there was a 6 gal "reserve tank".
someone ran the truck till empty and then filled it up
he noticed that the gauge didn't move until he had 6 gal already in the tank.
so add 6 or so to the amount you put in it.

the tank in the bronco ii is 23 gallons. the gauge runs to empty after about 13 gallons and gives you about 10 to play around with.

Gas Tank Quantity ?

Nutz...I got this previous posting a day late... I took old "87" out for about a 200 mile drive yesterday and got 18.7 miles per gallon with the AC on half the time (Florida) and filled up at about 13 gallons required on empty. I could have carried a 5 gallon gas can and done some testing. Wonder if I can convince my wife to do this as she's driving '87' to and from work this week?

My 1990 BII has a 23 gallon tank and when it says empty it is. I have put as much as 22.5 gallons in it before to fill it up. It also gets around 18-20 mpg depending ont the type of and terrain I am driving.

23 gallons on my '86. About what the needle reads, mine doesn't start reading 'till I've driven 180 miles on a full tank (about half a tank). I've never trusted my gas gauge. I keep track of miles. Sometimes the gas gauge works sometimes it doesn't, but I wouldn't make any conclusions by what it says.

I don't believe there is supposed to be a 6 gallon reserve tank in these trucks. I think it's a problem somewhere. My truck will go to empty and take 13 gallons to fill it up. It's an '86. My husband's '90 always took about 23 gallons to fill up. He changed the fuel pump in his truck last week, and guess what? Now his is doing the same thing as mine. There must be something blocking the floats from going to the bottom of the tanks. We're going to call the Ford shop and see if this is common.

Ok, talked to the shop, they said that it's the float inside the gas tank, and we need to bend it down more. It's just like a toilet tank float, and if it's bent wrong, it's not going to read right. We're going to try the 86 this weekend, since it's more empty now. We'll let you know. Angel

I just dropped the tank on my '90 to change the pump. It had been filled up before dropping it (argh!) and only 42 miles driven off of the tank-full. Owners manual says '23 gallons' and when I got the tank down, it was almost still full. Setting the tank up, I siphoned 4 complete 5 gallon cans and a 1-litre soda bottle full from it.
My B2 averages 23.5 mpg freeway with the 2.9 V-6 and a 3.45 rear ratio.
The fuel guage never worked since we've owned it, and I checked it out while we had the unit out. Using a multi-meter, the sending unit read 16 ohms at empty and 85 ohms at full. The problem with the guage was not in the guage nor the sending unit. It was the actuual float itself. It had a hole in it and wasn't floating at all (waterlogged). I patched the float with some fuel-proof Permatex-type stuff, and after dumping 5 gallons back into the tank (after re-installation), it read right below 1/4 tank.
