I recently figured out that the suburban tank I planned to use is too big. It won't fit in between the cross members. I used a 72 blazer gas tank in the truck in my profile pic, but it was carbed. The 72 blazer tank is rectangular when viewed from above, and the suburban tank I have is square. It might work in a lwb, but mine is a swb. I contemplated using a blazer tank again, but IIRC, the newer sending unit needed for the factory style electric fuel pump wont't fit in the blazer tank (larger diameter). i have thread specifically regarding the fuel system In the LSX forum. Their universal tank and pump module has been recommended.

Does anyone have experience with either of these or other recommendations for something cheaper than a boyd’s welding tank ?
