42 gal gas tank

[ranger danger]

I tried posting this in the Suburban section and got no response.
I need more range in my 69 Suburban!!! I'm looking at swapping out the 21 gal. tank for a 42 gal.
Has anyone tried the diesel tank for a 94 to 99 Suburban? I'm curious if the stock sending unit from my 69 will fit the newer diesel tank. If not then I would be looking at the gas 42 gal. tank from a 92-97 Suburban. Same question though, will the sending unit from my 69 work on the newer one? The problem I see with the gas tank is it has 2 extra holes in it that I would have to figure out how to plug.

Im not well versed on the later Sub tanks but am pretty sure that there were 31 and 35 gallon tanks offered in the earlier Subs / Blazers (square body). I got a 31gal. from an '89 Blazer in my truck. Went in pretty easy. Was able to change out the pump to the later FI pump real easy as well. Going from a 17 gal to nearly double is working out pretty well so far.

Thanks, I don't want to change to an FI. I would really prefer to stay with the oe sender. I know they make a 40 gal for the earlier subs that will fit, I was just hopping the 42 gal diesel tank would work.

Why not use the newer sending unit.. just remove the pump and add length to the feed line and put a tank sock filter at the line end..

The fuel gauge sender should be standard gm 0-90 ohm

40 gallon square body fuel tanks from the 70's - early '80's are available new (and cheap on RockAuto)

I would worry more that the arm on the original sender would be different and not read accurately.

Thanks everyone, I broke down and ordered a new 40 gal tank, straps and sending unit yesterday. $189 total from fleebay.
