Calling all Reg Cab, anyone have a 18 gallon fuel tank?

Well when I look at my vin on my Toyota account, they call it a 1996. I’ve always gotten parts calling it a 96. But anyway, the manual says 2wd models 15.1gal, 4wd 18gal.
However, my gas tank is also 1.5 inches down like yours from the frame.......

Im gonna let my gas tank go until the point where I know it’s close to running out(from experience) and I’ll confirm the amount. But I Also know I have my ultragauge set to give me a warning when I’ve used 16 gals of gas.. so I’m pretty certain mine is 18 gals and 1.5 inches down.

 

I bet yours is 15 gallons with it hanging 1.5” down.

The ultragauge I bet is not totally correct,
My scanguage will tell me I’m getting 25 mpg
when I’m getting 20-22 mpg.
What’s the most you have ever filled up Into the tank?



Looks like the manual says 18 gallons and I know mine is a 15 gallon tank, so looks like there were both available then.

Maybe the autos got a 18 gallon tank?

So did they use the same 15 gallon gas guage, and a different sending unit on the 18 gallon tank? The 18 gallon tank would need a 1.5” longer fuel pickup line.
And that’s why a few people are saying the most they have put in is 15-16 gallons in a 18 gallon tank?

 

Well, I’m just confused.
It looks like in that screen shot 4 wheel drive It’s 68 liters of gas, 18 gallons, 15 imperial gallons.
I didn’t know imperial gallons were a thing.
I’m gonna let my tank go down and see how much I can get in there.

 

I’m guessing there are 18 gallons and 15 gallons tanks from the responses here that were available

 

Interesting. I’ll take some photos while I fill up next

 

Imperial gallons are a British measurement, before they went to the metric system. If you ever work on a classic British car, the measurements are in inches, and you can use SAE wrenches on them. However, the threads are Whitworth, not SAE.

 

My 2004 4X4 has an 18 gal tank. I have
204K and get about 320mi a tankful on average.

 

So... I cant speak to what your truck came with for sure but it looks by the depth of the tank in the pics you posted it looks like a 15 gallon tank. The 15 and 18 gallon tank are the same except the bottom is deeper on the 18 a few inches. The flat pick up and pump unit are also longer on the 18 gallon. You can 100% swap them out on both 5lug and 6lug regular cab and extra cab. And this is plug and play no mods needed. I had a 15 gallon on my truck when it was a 5 lug and swapped in the 18 gallon then when I did the 6lug frame swap I used the 18 gallon. and am still running it. Here is 2 pictures of the front gas cross member it is the same on 5 and 6 lugs and a picture of a 18 gallon and 15 gallon tank side by side. Not the best pic but only one I can find. I do have a side shot of the 2 together Ill look for it when I get home tonight. Also have 2 18 gallon tanks for 1995.5 to 2000 for sale.

 

what does that epa sticker under the hood say
what model year does it conform, i think that is standard

 

I’ll go look now

 

Thanks! That’s very interesting. A new thing is learnt

 

Did you do this on a regular cab? Reg cabs have 2 tank straps and I would assume you need a longer strap, at least on the front, to accommodate the taller/deeper 18gal.

I could be wrong.

 

Yes on a regular cab. the 18 gallon tank was off a extra cab. The regular cab uses 2 straps and yes the gallon strap is longer. The extra cab uses only 1 strap and the front bolts to the carrier bearing crossmember.

 

So not quite a mod but you do need more parts than just the tank and fuel sending unit.

Thank you for the information!

 

you need the tank, tank straps and fuel sending unit. That is all

 

Well I’ll be dammed! I guess it’s been awhile since I’ve let my tank go empty to fill it all the way up. But I let it go to hereFilled up all the way to hereit seems as though I sure was wrong!

 

It does say 1996. So I guess I was right originally.... idk that’s always confused me. But it looks like 10/95 is past the cut off date for 1995.5s?

 

You definitely were on gas fumes there

 

Reg cab doesn’t have a carrier bearing, doesn’t have carrier crossmember I don’t think?

 

No carrier on the regular cab that's why it uses the strap on the front.
