is it really worth the trouble of relocating the gas tank to the rear under the bed???
and what are the common problems and issues when doing the install??

The main problem I've heard people talk about has been the location of the filler neck. The other problems I've read about are fuel pump type, venting, wiring and the looks of a fuel tank hanging on the back side. One person mentioned he didn't like the possibility of being rear ended with a tank full of fuel on the rear.

I've contemplated it but always decide to just leave it where it is. I figure it's been there for 40 plus years without any problems so far. Some people don't like the idea of a fuel tank behind the seat, but to me, it's safer than behind the rear axle. Plus, if it has a leak, I can smell it a lot quicker.

Some of the pro's are that you don't have fuel smell if the one you have is unvented and added weight moved to the rear axles.

i agree i guess i was looking for more room behind the seat for speakers, i just did not want to cut my doors, put it is a pretty standard move with the older trucks

I have done it and the only issue I have had was the filler neck, which I have made work, but it could be better. I wouldnt worry about crashing because there is a lot of frame rail that has to be destroyed before the tank gets hit. The suburbans have it so its not like you are starting from scratch. I would go with the metal or aluminum tank, not a fan of the polly tanks.

Smitty, Are you ever coming back to Huachuca? Still playing with mine. Wish you were here to kick me in the butt every now and then.

If you move it you will need to decide what to do about the spare tire.

I guess if you need the space for speakers or storage, you'll have to contend with the issues mentioned. I'd prefer that over cutting into the doors -but that's just me.

One thing to be aware of with tires in the bed. Make sure it's tied down some way. Tires ain't cheap these days and easy for someone to make off with it unless chained to something.

I'm in the middle of doing this now. There's a very cool spike tv episode you can find on their website by typing in 72 chevy truck. They put the filler neck behind the side marker light. I just fabricated mine for this, but I'm in a hotel right now and have no pictures. It's even easier on a stepside like mine than on the fleetside they used in the show. Good luck
