I ran the Tanks, Inc EFI tank at CoTA this weekend. Very pleased with the results. Performed down to 3-4 gallons left for me.

The biggest test are turns 17-18 which are a long continuous right hand turn. It was a constant 10 seconds at 0.9-1.0 G of load in my car. Fuel level was just under 1/8th of a tank at the end of one session, and just below 1/16th of a tank at the end of another session (point of reference - exactly 5 gallons was just over 1/8th of a tank when first filling from bone dry). I'm assuming I was 3-4 gallons in the tank at the lower levels - will confirm when I'm able to run it that low again.

Drove the car to and from the track that day as well. No issues. 250 miles round trip plus four 25 minute track sessions.

This is with the 460 lph walbro in tank pump in the duster EFI tank. It is running full speed (I did not set it up for PWM). With corvette filter/regulator. They recommend the Walbro 255 lph, which would theoretically drain the fuel basket slower.

I am pleased.

Yellow is 0.9 G. Red is 1.0 G

Awesome! Total investment for the setup?

$600 and change for the pump I went with. Closer to $500 all in for the 255 lph pump, which will handle 600 flywheel hp or so.

I think I need more pump, it acted up again the other night in real cool air, lean shut down. My pickup is in rear of tank so I really don't think its starvation. You were smart to step up pump size.

This pump is a different style altogether from the 255. It's a turbine pump. Specifically the Ti engineer told me it will not cavitate, has 6000 hour life expectancy, and is built on the same line with same materials as used in a number of current high hp oem applications. The fact it can also go PWM sold me.

Not to mention I could swap to e85, or stay on gas and run a dry shot of nitrous. Room to grow.

I would like to PWM the pump at some point. Goodysgotacuda did all the legwork, I just need to wire it up and see if it works. I figured full bore flow would make for a harsher test environment, so PWM will only make it better IMO.



And of course I bought a spare. Because I break things. haha

Excellent! Now go PWM, and bump up the longevity of the pump some. I guess I'm sold on going with that tank.

I think im gonna try a Deatschwerks DW300. Its a 320LPH that replaces my 255 Walbro.

Great test and good result!

Yeah, this is great to know. When I go EFI with the Dart, this is the route I'm going to take.

right on, wished they made a 71-74 bbody tank, their prices seem more than fair

I have that tank in my duster I really like it

I'm also about to install the Tanks set-up for the street Valiant w/ the 255 pump. I'll be using the Fitech EFI with return line, E85 fuel, on my 408 (525hp). Super stoked to have this available for A-bodies now!

That will pretty much be my setup in the future minus the E85. Let us know how it goes.

I don't think the 255 lph pump is going to be enough for that combo on E85. I would recommend bumping up to the 460 lph E85 pump that I am running.

Glad it works well. How's the fuel gauge behavior? The "fuel cell type" senders never really impressed me in friend's cars, which is why I went to the Aeromotive Phantom in a stock tank.

Using a marine style sending unit and an aftermarket gauge should remedy any fuel gauge behavior concerns.
