Semi Truck Fuel tank in bed questions
i dnt want to offend you by any means but i am going to give you sum advice that could save your life.
i assume this is a used tank.diesel vapor will blow up on you so your best bet is to use some plain old tide soap and water to wash the tank inside and out until you cannot smel diesel any more.be patient this will take a while.and then when you go to weld keep it purged with co2 in a well venalated area as long as your cover gas dont blow away just dont sufacate yourself.dad and i have used this method several times to modify diesel tanks after he had one blow up on him.good luck

That is another internet "fact" that I have never seen in writing. I have a gravity fill from my aux tank to the vent line of the main tank with a ball valve. My last DOT inspector gave me an attaboy sticker for my windshield.
Well if thats the case I wouldn't mind just spending 69.99 for the gravity feed kit. From what I was told on the gravity feed issue is that if you happen to flip over the fuel will poor out. By all means I have no idea on how all this works but with you alls help I am sure I will get her done.
I'm putting a little salt and pepper on some crow. I did find a web site for DOT Hazmat that indicates that 119 gallons and less are OK for fuel tanks so it looks like your tank, in fact, is illegal. Here is the link. http://www.phmsa.dot.gov/portal/site...gnextfmt=print
I helped a friend of mine hook his into his truck, took metal fuel filler neck off, drilled it and welded a bung onto it. Then screwed a barbed fitting into it for the hose. Bought a cheap 12V pump from Carquest and hooked it up inline. Them mounted a switch on the dash for the pump. He just flips the switch until the guage reads a over 3/4 full, then shuts it off, works great for him.

I did that 5 or 6 years ago, great minds think alike...
Thinkin of switching mine over, I've just got a 12V transfer pump on it right now, cause I had one handy. It'd sure be nice to refill while goin down the road.

Look at part D.http://www.fmcsa.dot.gov/rules-regul...ction_toc=1898
Well, like I said, didn't know if it was correct or not, just something I ran across, seems to me now, they put just enough info to make it look like you had to buy their system to be legal
