Dongray,

3” from the pumpkin to the front of the tank.

I do believe the tank could be moved back so the filler is on the aft side of the crossmember. There is 11” from the back of the tank to the roll pan (option I added) on my truck. Of course that that will make the tank more visible and maybe not as crash worthy being that far back.

I’ve attached a picture of the tank, forward strap attachment. I attached a piece of angle iron to the bottom of the coilover crossmember. Slots for the straps to go thru were added to the angle iron.

If my memory serves me right, the straps are from a 66 Chevelle.

Hope this helps
