Ok... Ive gotten rid of my saddle tanks and am ready to buy a NEW tank for the rear tank conversion for my pickup (89 v3500) ,,,Ive already read the blazer tank in a pickup article but it didnt referrence whether the 32 gallon tank had enough clearance to fit... or what about sub tanks (late model efi)

thanks

not sure if this helps, but I tried to put a '89 sub tank in my '82 Blazer and it was too big. I can get the measurements if you want them. I know the Blazer tank is like 26 1/2" by 27"

i was thinking about the 31 gal k5 tank,,,,, my concern is that it might be too close to the 14b.....

truck is a dually chassis cab and I have tried a 25 gal tank and it fits ok...

anyone?

I've got a stepside, and the 31 would have been too tight for it. Maybe if I had a body lift.

I have done this swap quite a few times, on a long bed like yours the 40 gallon suburban tank will fit, you need to cut out the second to the last crossmember on the frame,,move your brake line bracket ahead 2-3 inches, use your suburban straps and put a cross member above the rear axle to bolt the straps to.
This combo will leave about 2-3 inches in between the axle and the tank,
if you have a lift it will be even more.
