anyone fed the stock tank from a fuel cell?

[dville_gt]

i currently have an 8 gallon cell in the spare tire well.

i am considering switching to e85 and putting in a stock sump'ed tank.

if i run both that'll give me around 23-24gallons of fuel which should get me ~200 miles on a tank which is reasonable.

the best way I can see to do it is weld up the stock vent hole, pump inlet, and filler neck hole with plates.

to connect the two cells i'd run the -12 from the cell to a bung on top of the stock tank (probably put the bung on the plate for the stock pump inlet).

continue to return fuel to the top of the fuel cell and use the fuel cell's vent, but pull fuel from the sump on the bottom of the stock tank.

i'd fill the tanks via the cell.

why not just buy a 20 gallon cell.

I know a guy who can build you a beautiful new fuel cell

these are options, but i don't particularly like the way the high capacity cells look hanging under the car and don't want to cut out the floor pan to facilitate a 20 gallon cell.

as an added bonus i already have the cell, already have the stock tank, all i need is to weld on a sump and some block-off plates and a couple of fittings.

Fixed that for you.

If you are going to run both, why not have two tunes and a switch, and run race fuel or e85 in the cell and pump on the factory tank?

not a bad idea, the problem that would arise would be how you would shut the feed/return off from one cell and divert it to another cell. i supposed you might be able to find some type of Y diverting valve or something, but i've never personally seen anything like this.

backflow valve in each and seperate pumps would be a thought, or im sure there is some type of solenoid out there that would work.

or 4 ball valves. one on each feeds to the pump, one on each returns to the pump. cut off the fuel tank feed/return and open up the cell feed/return and vice versa.

Fuck I forgot returns, yeah, a couple ball valves would be the way to go id guess. Maybe something like the dual tank setup on the old pickups like the ford I had in highschool?

[dville_gt]

From the cell or tank's outlet hose

To a -12 to 3/4"NPT fitting


which would be threaded into one of two ball valves like this:


threaded directly to a Y fitting like this:


back to a -12-3/4"npt fitting


into the pump


The return would be similar except 1/2" to -8 fittings.

what a clusterfuck that would be.. just pick a fuel and build the system to work on that fuel.

if you go E85 just know you will have to stop more often then on 93. carry a 2 gallon gas take with you with E85 incase you run dry trying to find a place.

even cheaper/easier would be to just have ball valves on both inlets and returns and then just manually switch the feed line/return lines from one to the other.

Could you possibly over complicate everything you do to the car?

Just convert to e85 or do what I've got Todo.

Buy a 30 gallon drum of race fuel. Refill at The house before you leave.
