i didnt know if i should pose this question here or in tech forum. i am trying to make a decision on cutaway chassis for a project im doing. while i would like to get best mpg, my biggest need is to have extended driving range. i would like to give a promaster a chance, it has some real plusses for me, plus should get 2-4 better mpg, the problem? it only has 24 gallon fuel tank, i can get 55 on ford and 57 on chevy. they all come with a fuel tap for generator, is it possible, instead of sucking fuel out, could i mount aux. gas tank in promasters wide open frame, and pump gas from aux. tank to main fuel tank? any thoughts or ideas would be appreciated.
*on edit, i read online for about two hours, i think i figured it out. i was afraid the line was pressurized, but that would make no sense, its main purpose is for motorhome use, so you would have to have key on for fuel pump to work, so it has to be a simple pickup tube that reaches down as far as 1/4 tank so your generator cant run you out of gas. reading alot about gravity transfer i did figure out would be best to install check valve, if not and you ran aux. tank empty, and main tank below the pickup tube it would vent and cause check engine light to come on, of course with that much fuel i doubt i would run it that low. still would appreciate any thoughts or comments.
