Tanks Inc question

There are several great options available these days to retrofit and enhance fuel delivery for both EFI and high performance carbureted upgrades on our old cars.

On my '68, I used a new stock tank, a new 3/8" feed w/ 1/4" return sending unit for my EFI conversion. I did upsize the return to 3/8" tube using silver solder, as I am running a surge tank system with a pusher pump just outside the stock tank. This side of the fuel system was low cost, easy to plumb and works with the surge tank set-up similar to the Fitech system. Low pressure lines feed and return fuel from the tank at the back of the car to the front mounted surge tank at 0 to <1 psi. The only high pressure fuel runs between my surge tank and the fuel rails with extra fuel being bled off into the surge tank. I like that feature.

In the future to eliminate the external pusher pump, I do have a Deutschwerks in-tank pump that fits through the sending unit opening and attaches to the sending unit. I could have done it this way initially, but went with the external pump while rigging everything up as I had the parts on hand.

The system supplies air bubble free fuel all the way down to 1 or 2 gallons in the tank on the road course at Willow Springs. It was inexpensive regarding the tank etc, but the high quality surge tank with regulator cost $600 including the Deutschwerks fuel pump. Fuel lines are aluminum tubing with EFI rated rubber lines and clamps on the low pressure side with braided Earl's lines and fittings on the high pressure side.

I am considering retrofitting my other cars carbureted fuel system with a Vaporworx Corvette style pick-up/pump module, pump controller and 4 snowmobile pick-ups, with a bypass regulator until I inject that motor.

Notice the canister is a bit smaller in diameter than the Fitech unit and has a full return to the tank. Also notice the 2 micron fuel/water separator plumbed into the low pressure side. I have two of those filters on my fuel system. One located just behind and upstream of my surge tank, and one at the rear of the car just before the pusher pump.
