Nice tank
Couple wacks to the seam where it sits in the cradles and it slid right in. Good price, seems factory quality!

Would purchase again if needed.
Excellent, strapped right in and worked like OEM.

Fit a long bed square-body Chevy great
It is working well on my 85 K20, seems like good quality welds and metal, no more leaky gas tank. No issues installing other than the job itself is a little challenging getting the gas tank up and mounted to the frame

Worked perfect
My 85 GMC pick had a rusted out gas tank. This product worked fine. It was a bit tight. The seam sticks out a bit further where the brackets go around the tank. Had to bend it a bit. But it worked fine. Way cheaper and quicker than LMC. Don't be discouraged if it doesn't seem like it will fit. Because of the seam.

Good quality tank
It’s a good tank. However, I did have a hard time fitting the straps around the tank because the welded seam had to bent down to get the straps around the tank. Other than that it’s worth to price and I would recommend to anyone needing it.

Doesn’t fit 1984 Chevy.
This is so annoying. Amazon not making sure of fitment and businesses not giving instructions. Am I supposed to bend the lip down? Will that ruin it? SMDH

Looks exactly like the factory tank I took out..... My tanks on my truck are 20 gallon so the tank is just over 4 feet long & if u have 17 gallon tank it will be under 4 feet long.... Just to help anyone out that is wondering what tank they have
