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?

Thanks,

John

 

John , SWB , LWB , ?

 

It's a LWB 4x4. I didn't think twin tanks were available on the SWB truck.

 

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 .

 

hey man,
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 found an earlier post that addresses your question.

see https://www.ford-trucks.com/dcforum/DCForumID39/391.html

 

my '87 is SWB and has dual tanks, but the front one has a hole in it and the guages dont work, gotta get those fixed sooner or later.

 

I believe the way it works in the late models is the 2WD SWB have 2 tanks and 4WD SWB have only 1. Sure wish I had 2.

my truck is 4x4 and is SWB and has dual tanks.

 

I’m pretty sure 92" was the last year for the dual tanks in a SWB truck.
My truck is 92” SWB, but does not have dual tanks, wish it did though.

 

I have '93 F150 2WD SWB w/2 fuel tanks. The owner's guide shows the following capacities.

4x2 SWB front 16.5 gals, rear 18.2
4x2 LWB " " 19.0 " " 18.2
4x4 SWB (none) " " 18.2
4x4 LWB " " 19.0(3) " " 18.2

The foot note (3) states: With E4OD trans diesel engine 22.0 and all other EFI engines 16.5 gals.

Hope this helps.

 

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.

 

I'm pretty sure you could get dual tanks in any configuration. A single tank was optional.

Hey,

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.

Hope this helps,

John
