Do you know what is so awesome about this site?

i dont know if im allowed to post this i know there is some new rules about posting products and what not. if so moderaters please remove this and explain the rules to me a little better so i can understand it better.



anyways to the subject at hand. im curious how much interest there would be in an in bed fuel tank for about 500 bucks. the tanks would be about 50 dollars, and would work much like a transfer flow.



my idea is to build a tank that would fit in the very front of the bed and probably work with most all tool boxes though probably not in the short beds. just the long beds. as far as the tank goes it would be approximitly 50 gallon capacity with a small transfer pump to be able to pump the fuel into the factory tank. the tank would come with a pump and solenoid to keep fuel pushing itself through the pump, as well as all the hoses and fittings needed to hook it up to the main tank. you would have to decide how exactly you would want to wire it up. though i would provide a diagram of how i would do it.



like i said im thinking about doing this if there is enough people interested to make it work. the total cost for the tank and everything ive said would be supplied would be about 500 dollars. anyone interested?
 
I tried several pump and gravity flow configurations. None of them really worked well. The best way I found to do it and the way it is on my truck is to use a tank selection valve mounted on the frame on the driver side near the lift pump. The type of selection valve I used only selects the input. Return is stock. So if I select input from the bed tank the return is to the main tank. That works really nice. The stock lift pump moves fuel at about 50 GPH so most of it goes back to the tank. The only problem is that you have pay attention because it fills the main tank so fast it's really easy to run it over. The stock 12 valve lift pump is a lot more reliable than any electric pump so I have not had to mess with it since I installed it.

Plumbing it is simple. Install it with fuel hoses where the stock supply fuel hose is. Installing a line from the bed tank to the tank selection valve is easy too. Another thing is that the fuel from the bed tank is filtered by the stock fuel filter before it goes to the main tank.

My current setup is pump-assisted gravity feed. I need a pump because the outlet on the aux tank is on the top of the tank... but the main tank will often times draw enough vacuum to start the flow itself, and I only need the pump to top off when filling in most instances.



I used the "manifold," provided for the FASS return, that is placed in the fuel fill hose as a input point for the aux tank... I drilled and tap this fitting for the aux tank connection, but it is NOT plumbed into the FASS return line. I tried the tank vent line first, and had bad results; I think there is a check valve in the vent line...



I'd like to get an aluminum tank that either fits against the bulkhead to under my existing tool box... still considering having one made.
