I have never used the blazer tank, but from what I see is the top of the tank is also sitting way to high unless your gonna put a bed lift in there to raise the bed about 4inches, From what I have seen pictures of some of these trucks and guys using the blazer tank, I would never do it, because the tank sits considerably a lot lower than the frame. almost allowing something in the road to come up and puncture it. Some of the trucks I have also seen when lowered the tank seams to be almost hitting the ground, this can't be good in my book and would severly feel a lot more safer with it behind my seat then there, or else it was something else I was seeing.

If what I understand is correct, you're saying the cross member for the bed hits the tank. When I did this conversion with my wood bed I simply removed that cross member. Unless you plan on hauling some seriously heavy stuff, you really don't need it in there. As for the holes on the chrome strips, you can cut off the bolt heads that go there and glue or weld them in the holes to have the appearance of there being a cross member there.
Now for the next concern: USE THE STRAPS!!!!! If you bolt the tank diretly to the frame, when the frame flexes (and it does) you run the risk of rupturing the tank of it is solidly mounted to the frame. The straps are made to cradle the tank, and put no pressure on the tank walls. Bowtie 67, I have mounted the tank under the bed and absolutely love it. To date it was one of the best mods I have done (along with power brakes and a sway bar and H-4 Lights). I don't feel that the tank hangs too low, but my truck is stock height. It hangs about level with the rear bumper, maybe an inch or two below. If I was dragging a truck on the ground I might be concerned, but other than that I feel it is safe. If it wasn't, why would they put them on the blazers like that, and for that matter on all current cars the gas tank is in the rear? Jeep Cherokees have a tank that hangs much lower, and that is supposed to be an all terrain vehicle. I feel a lot safer with it under the bed than in the cab wehre fumes are present and can rupture in an accident and pour flammables all over me or my two year old daughter. Sh is the main reason I moved the tamk. JMO Hope this helps a little. BTW. to all that have asked for the pics in the FAQ section for the How to Install on the tank. I am still working on getting them off my other laptop and will post them again as soon as possible. Shawn

The tank does not sit any lower than it would under a Blazer or a Suburban, if it is mounted so that the flanges are resting on the bottom of the frame rails. All you need to do is notch the bed cross sill 1 1/2" so that it will set against the bottom of the frame rails. These tanks are direct replacements for the Blazers and Suburbans and the dementions are the same. Matter of fact they are slightly smaller than the 67-70 Blazer tanks. They are no more risk than they are under Blazers and Suburbans. WES www.ClassicHeartbeat.com

Pics of your install
Hey Shawn,
I just bought this relocation setup from Wes. So, I'd be eternally grateful if you could get those pics posted just as quick as you can man! Personally, I'm real excited about the conversion. And I agree about the safety factor. If it weren't safe, then surely they wouldn't be for sale?! Thanks Bobby

71GMCStepside, Well lots of things are sold that are not safe...lol However this tank and set up has been proven for over 35 years. The width of the rear of the frames on the pickups verses Blazers and Suburbans are the same, so hanging down too low is just not an issue!! Maybe if you are lowering your truck down to the ground, and if you are lowering it that much you wont be driving it that low. Heck you would get stuck on speed bumps..lol I wouldn't sweat the safety factor... WES www.ClassicHeartbeat.com

Is there a risk of the fuel tank rupturing in the cab? YES
Is there a risk of it rupturing under the bed? YES I guess the primary question is, which one do I think will give me the least amount of risk to me and my family? Under the bed. I am currently converting my tank to the blazer location under the bed. It is the only money I have spent on the truck that my wife said was well spent.

WES is right, I just did this for my steel floor truck and had to notch out the rear bed support 2 inches and weld in metal to replace it. This tucked the tank up as far as it could go, does not hang to low in my opinion
