i don't mean THAT far forward. i should have clarified. what i'm thinking is moving it it the length of itself forward. picture the stock location, you know how there's two crossmembers that it mounts to? the back of my tank would mount off the front crossmember, i'd just weld it in backwards. if i had a tank a tank in the stock location and one where i want to move it, they would touch. so really, the new tank would be over the rear axle and the end of the driveshaft. i'm going to have a 4" suspension lift so i'll have lots of room under there, and i think my tires would eat the rear quarter long before there was enough flex for the axle to hit the tank.
Yeeeeah that won't work.
The only way to make it fit that far forward is to have a body lift.
A suspension lift will not give you enough clearance unless you put some lower bump stops, the axle will still be able to go up as high as before the lift or close to it, and the way it is stock there is barely a few inches above the axle.
Give me a couple of days to take some measurements and I will tell you what options you have, I already have been thinking about this for a few years so I exhausted lots of options in my head now I need to get up and start my measuring.
). Dleroy43 had moved his 'burb tank up behind the back seat and supended it halfway through the floor. That worked OK, but limited shock mounting options. I'm not picturing a way to do this on a Blazer and still have a back seat. Maybe saddle tanks from a SB pickup, but that'll kill your ground clearance under the sides.
don't know what year your truck is - my frame is an 83, and the bends in the frame would prevent it from being moved forward. perhaps on an older frame where there weren't footwells for the rear passengers it might work?
