Diesel tank and filler for OD transmission

[Harrinad]

Has anybody found a good diesel tank and fuel filler / vent to use if you swap a longer automatic transmission with overdrive? I was thinking about the j10 tank but it is a bit small.

I was looking for a larger tank to swap in years ago and settled on a 33 gallon tank from a diesel van. I think it was from a 1995 Chevy G30 with the 6.5. It has a 1 5/8 inlet and the vent tube is on the pickup assembly. I put it under the bed in place of the spare and it fit quite well.

I used my factory 1974 filler neck and used the round plastic filler assembly from a Jeep TJ and moved it behind the wheels. It has been working great for almost 10 years now.

There is also a 22 gallon version.

Do you have a picture by chance?

Look for a 1982-87 Blazer/Jimmy/Suburban Diesel tank. About 25 gallons measures 28 3/4" x 28 1/8" x 10 3/4". I have one that I'm going to use for my Diesel Wagoneer swap. I have fitted it up in the space where the spare tire was and it does fit.
Here's an example.

Good idea and not very expensive. What did you use to support it? Does it come with straps?

I have only done the quick fit and it does fit up inside the area for the spare tire.
If I remember right the exhaust for the v8 is too close to the blazer tank, but I'm going with a 3" exhaust and will reroute the exhaust some where else.

Straps are extra.
Have not done any planning for the tank straps/support, but I did purchase straps for the Blazer to use on this project. For the rubber insulator on the straps I'm using inner tubes cut to fit.

I will have to get pics tomorrow when its daylight; but here is the exact tank I put under the bed in the spare tire area. It doesnt leave much room for exhaust to go out the back though. When I built the 406 stroker, I was running dual 3" sidepipes. When I swapped the diesel in, I put a 5" stack on it up through the bed so I never worried about routing exhaust out the back.

I used the in tank fuel pump when I was running gas TBI, then swapped the pump assembly for the diesel pickup assembly when I swapped to the 6.5 and later, the 5.9.

Does the level sensor work with the stock Grand wagoneer wiring?

I believe your asking will the GM sending unit work with the Jeep fuel gauge?
Only if they both have the same specs for the the fuel gauge, meaning the ohms difference between full and empty match.

See https://mtscompany.com/sendingunits.htm for info.

When I swapped out the 19 gal tank in my ScoutII for a 40 gal tank I had to make the scout sending unit fit the new tank. The ohms have to match.

And they have the tank(s) we need in plastic. If I didn't already have the metal one I'd buy one theirs.
