I need a little help on the fuel tank

[Prostreet 72]

I have gotten quite a bit done on my build over the holidays, but have run into a few sticking points. All with regard to the LMC fuel tank kit. I agree I should have used the Fuel Cell Guy, but this is what I had, so I went with it.

First off, shouldn't the tank be isolated from the frame of the truck when installed? Mine is hard aginst the frame all the way around it.

The second question is which direction did those of you who used this tank run the straps? Front to back, or side to side? It appears to be stamped for them to go side to side, but with no directions, who knows?

The third question is the amount of the tank above the frame rails. I know I need to clearance the crossmember, but dose the picture I attached of it look right? It seems high. Not sure, once again, no instructions. Got to love LMC.

Hey, I also posted a picture of what I started with. POS!

Thanks;

Chris
