1970 4X4 Gas tank relocation

[4 Speed Dave]

I am doing a full frame off restoration of my truck and will be relocating the gas tank to under the truck as I am going with EFI and want it out of the cab. All the kits appear to work only for 2WD trucks as the 4x4 has a frame cross member in the area where the tank lives. What do the 4x4 guys do to relocate the tank? Thank you

I have done it using suburbon fuel tank cross members from a square body and a 96 burbon tank
Done it with a 76 burb tank as well though i went back to in cab tank after i picked up a fleetside box i didnt have the skills or welder at the time to add a gas door

Relocate the one on the truck and buy another crossmember to support each end of the tank (straps)

I relocated my tank to the the rear between the frame rails on my 1970 C10 4X4. Went with a Boyds Welding tank. It has tabs on both sides that rest on the lower frame rails. Perfect fit, sturdy. No issues what so ever.

I did a 5.3L swap in my 70 K10. I used Rick's Tanks made in Texas. Stainless steel tanks. High quality, but pricey. IMO well worth it.

I can also give a thumbs up to Ricks Tanks. Had them make me a custom tank for my flatbed. If my math is correct it will be about 45 gal
