Be vary carefull welding on fuel tanks. It is not the fuel but the vapors that will ignite when welding on them. I learned that the hard way. That said, remove all the fuel you can from the tank, then remove the caps and run an air hose from your air compressor into the tank and let the air run for an hour or so to remove any vapors. Then you should be good to go.

another option would be to move the tank back to clear the stacks, then build a custom storage box between your stacks that matches the finish of your tank. or cut a plate to fit between the front of the bed and the tank. both of these options would be easier and safer than welding on the tank.

rather than run compressed air into tank i would run shop-vac hose in filler and pull air out. diesel not as bad as gas though, when welded my mustang's tank filled it as full as possible with water.

dont bother running air into the tank, fire needs O2 to burn, so your not helpin anything. best thing to do is go down to your local welding shop (they are everywhere) and get a carbon dioxide tank. its a very heavy gas, non flamable and will keep you safe. just put a regulator on it, put the hose in the tank and pump it in. you can also fill it with exhaust from your gasser car or truck. same thing, it will fill with the carbon dioxide and push any oxygen and or vapor in there right out the top.

oh, and being a proud owner of a in bed tank, if i may suggest one thing. throw a baffle or two in that tank. you'll notice a difference when the tank is anything less then 3/4 full. it really can throw extra weight against you in a turn or effect your stop and go's. plus you'll feel it sloshing around for 2 minutes every time you come to a stop.

yes a baffle would be a good idea as have hualed around barrels of oil and diesel and they can get to sloshing around pretty good to if not full.

I have seen welding done on a home heating oil tank done with the exhaust of the truck routed with make shift tubing into the tank to remove the air. It kinda looked like a precursor to a bad day, but it worked out fine.

+1 on this suggestion, seen it done and it looks nice and is functional too - depending no stacks diameter you can use the storage box for stuff like ropes and chains and spare fluids for the truck, even maybe some tools.

Yah, those really have the habit of throwing their weight around you and also sloshing around in a turn - of course having a full vinyl bench seat that is flat as board may have something to do with it, lol... But I'm pretty sure that ain't quite what you meant
