Does anyone know that the individual capacities are of each of the twin fuel tanks on a 95 F150? I thought that the combined capacity was 37.5 gal but my tanks seem to be a lot less than that -- about 15 or 16 gal in the front, less in the rear. I haven't run the tanks totally empty, but I've driven both well below "E." Do these tanks silt up or something?
I thought the same thing about the SWB , but it lists the SWB front tank as 16.5 Gal & the LWB as 19 Gals for the front tank & 18.2 Gals for the rear . I cant say for sure , But I think I have seen some SWB later model Ford Trucks with dual tanks .
to figure out exactly what the capacity is you could run one dry, then fill it up and let the other go dry and go fill it up. when i hit the E on my back tank i still have 8 gallons in it, so i dont much trust the gauges, i just drive about 450-500 miles and fill it up. good luck and hope this helps.
I just purchased an 87 F-150 with dual tanks. I filled up both the day I got it and I put around 15.5 gallons in the rear tank and around 17 in the front tank. Although I was not totally empty in the rear tank but I was in the front tank. I also noticed a sizable dent in the front tank when looking at the underside of the truck so the capacity may be more that I put in them.
I have 1995 F-150 2WD SWB with dual tanks, and I am finding it hard to believe that the rear tank holds more gas than the front does. I go almost twice as far on my front tank then I do on my rear tank. So for the past 5 months I haven't even used my rear tank, thought there might be something wrong with it.??? My dad seems to think that some how gas can flow from one tank to the other? I doubt it, but is it true? I've been under the truck but haven't seen any signs of leaks, so I really wouldn't know what else to look for. Thanx for any help.
There is an earlier post saying that any unused fuel is pumped back to the front tank -- regardless of whether the front or rear tank is selected. (I think the owner's manual mentions this too.) So, for example, if you're empty on the front tank, switch to the rear tank and use it up, then switch back to the front, there will be some gas in it.
