Luce, How did you get a surge tank inside the main tank? The venturi pump is a second electric fuel pump? Please tell me more.




I made my own tank, 16 and 18ga 304 stainless, and it included a 1 gallon milk jug sized box, 1/2 open on the top.

I got the idea from my 88 ramcharger.

Where the return line comes back to the tank, it's pinched down to 1/16" nozzle. It provides 30 psi backpressure when the pump is running full speed (and the engine is using zero of the fuel) so it doesn't interfere with the regulator. Than nozzle is at the bottom of the tank, and it squirts into a 1" tube that enters the box. The velocity of the fuel out of the return drags gallons of fuel per minute into the box, keeping it full at all times.

Found a pic. I tested it in the swimming pool with an old fuel pump pumping pool water. You wouldn't believe how much fluid the nozzle drags in. I would say better than 1200 gal/hr. It could fill in under 3 seconds. The flat bottom sits and is welded into bottom of the mail tank. I also added a skirt around the cutout so it would suck the last 1/2" of fuel from the main tank.
