ok so I have 2 16 gallon fuel tanks on my truck.
i also have a large 2 seater atv that fits perfectly in the bed of the truck and when it is in there i can shut the tailgate quite nicely. SO i prefer not to get a fuel tank that sits in the bed, unless someone makes one that would lay in the middle of the bed and allow the atv to drive on either side of it.
thanks

 

My 69 has two in-bed saddle tanks. They are shaped to fit in the area in front of each wheel well, but are no wider than the wheel well so they do not block usage of the main part of the bed.
No clue where you'd get 'em, but maybe it's an option for you.

 

What exactly is your question?

Are you looking for more capacity?

There is another thread about tanks and someone just posted a link to an oversized rear tank, I think 38 gallons? It is a rear tank that hangs down farther where the spare usually sits. I believe it was originally designed for Bronco's but many people put them in trucks too.

 

Lmc Sells 38 gallon rear fuel tank, I did both of my trucks, the only time I dont like them is at the fuel station. Empty my range is 700 and loaded 350. If your truck is newer than 89, you just have to cut notches in the tank to make your sending unit fit.

 

Just depends on how much you want to spend... $100- a few hundered will get you what you want...

I went with a used bronco tank, but that option may not be for everybody...

 

Might want to double check your tanks as well, should be twin 19 gallons as far as I know, figuring your after more capacity your best bet is probbly the bronco rear tank just have to relocate your spare.
