Just using a 2.5 gallon plastic gasoline can, some fittings, the pump, a filter and hose to bring it up front. I also have a low level indicator..thats it!
I can e-mail you a few pictures of my set-up of a trunk mount system. I like not taking time to refill the 1/2 gal. tank up frontevery three days.
I have a 5 gal. fuel cell / back pump / filter setup and really like it.
It is OVER KILL, but it works real good. If you like a few picture, email me at : dadmomcat@juno.com
