tank size

[HVACTECH]

So I purchased my 2001 4x4 f250 7.3 psd about a month ago and I have only really driven it on the weekends. This might sound dumb but how large is the tank I was at 1/4 on the guage and put 16 ish gallons in and Im over full .. needle is slightly over. I drove about 50 miles and im 1/8th of a tank down from full ... I think my fuel sender might be reading wrong and Im about to go on a trip in this truck for 3 hours and I would like to know fuel mileage so I can keep track of it.

long bed or short bed?

long bed is 35gal

Using the search button would show you a million threads on this, but if your truck is a short bed then it's a 29 gallon tank. If its a long bed, it's 38 gallons. That's straight out of the owners manual.

thanks for the help Zaairman and Jarrod B Its a short bed. For some reason I couldnt pull up a good search on this using the powerstroke.org search. I typed in fuel tank size and bad fuel sending unit , and bad fuel reading in the search bar but I never found what I needed. Im probably just using the search system incorrectly. I dont have An owners manual for my truck but I have seen a posting to get them here online so im gonna download that and read up a little thanks for the help. By chance have yall run into the issue yourselves or ever heard of it?

Thats a cool link consider it book marked

Fill it up and then figure 14 mpg x 29 for how many miles you can go without running out. Yes I am allowing a large cushion. If you are towing use 8-9 instead of 14.
Try smacking the tank, hard and I mean hard with a large rubber mallet, sometimes this will free the float.

that sounds like a good idea nch, but dont hit it right where that pickup tube is. might break that off and ending up pulling the bed or tank to replace that.

ill try that, I believe its the resistor failing on mine. Right now ive driven about 70 miles and im a little lower than 1/3rd of a tank down from full. Im going to drive 200 miles in it and then fill it back up and then use the amount I put back in as a divider of 200 to find out round about what my fuel consumption is at and then I will multiply that by 29 to find out how far I can get on a full tank. But most likely ...im gonna pull the sending unit and replace it before the month is over. Thanks for the help guys .. and thank you POWERED SPARKLESS my manuals still warm and fresh off the printer.

our 88 f350 did that on both tanks. gauge bounced around and stuff. replaced the sending units and have no issues since. and that was 2yrs ago
