Fuel Tank Conversion Question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

dkooi · 12-16-2004, 03:04 PM

I'm in the process of installing a blazer fuel tank in my 72' Chevy fleet side shortbed with wood floor. I have the tank in position between the frame rails and can see that the filler neck is going to interfere with the bed support, precisely where the bolt goes through that holds the bed to the frame. I could re-drill all 8 holes (4 for the straps, and 4 for the index tabs on the tank) and move the tank towards the rear, but everything is powdercoated and I would like to avoid that if at all possible. Plus I don't want a swiss-cheese style frame with numerous unutilized holes. I'm wondering if anyone has come accross this problem and how they handled it. Any insight and/or pictures would be greatly appreciated!

I had the same problem. I took the tank back. You have to hack out nearly all of the rear box crossmembe. If it's a poly tank you have to heat the area around the filler neck and tweek it to the position you need it. I would not use that tank.

I knew that I was going to have to notch the crosmember quite a bit, but the problem with the filler neck position was a total suprise. And I steered clear from the poly tank because I thought the hot Arizona sun might end up distorting its shape. I suppose I could take the crossmember out of the equation completely, but I'm afraid of not having the proper support for the bed.
