A1000, stock fuel tank w/ baffling okay?

[ss dave]

I couldn't help but add my experience. I have had two Ricks tanks in the same vehicle. 69 Camaro with LS7, 44# injectors at 58 psi., both tanks with the A1000 and a parallel fuel system.
Had issues with the stock Ricks tank, at low levels the pressure would drop, also around a right turn at 30 mph the engine died. Talked with a Boeing jet fuel tank designer and he suggested to put flap baffle doors in the tank around the pickup.
Hector at Ricks was great and did that along with a narrowed tank AT NO EXTRA COST-FREE! kud dos to Hector. Unfortunately, same problem. At low levels the pick up will starve.
I am going to ask Hector to build a tank with a sump and place the pickup in the sump. This is how the Factories do it and it would not require any extra tanks.
I have talked with Tyler at ATS and he stated they did not have any problems with their Ricks tanks and Bosch pumps. They run a dead head system like in Bad Penny. Wonder if Steve has any issues?

I would have think it would have been documented here by Steve if he had fuel tank issues, but then again maybe not....

Yeah I have spoken to Tyler about the same thing. Have not heard of many having the issues you are speaking of with these aftermarket tanks. Only with stock tanks.

Please keep us posted with what you decide to do and how it works out.

thanks

Most others with a similar powerplant/ fuel tank setup run a dead head type of delivery, ie. Bad Penny. Maybe that system keeps fuel pressure more constant than a parallel system, despite occassional starvation at the pickup, I don't know. I know that the return is less in length therefore volume, and the return would be quicker to the pickup. I need more info/ advice, any comments are appreciated.

Deadhead vs paralllel really has nothing to do with the pickup setup. Fuel starvation around corners is about control of fuel movement.

Jody's surge tank is the best possible solution. Proper baffling in the tank is the next best solution, and the OEM "pump in a bucket" approach seems like it would work well, but we haven't heard from late model OEM guys about their autoX or road course experiences.

Hello again, I was just thinking that after reading alot of discussion on the subject that "maybe" my fuel was being returned hot to the pump and causing vaporization which could contribute to starvation. I am trying to do anything and everything to optimize my system since this is a driver.

Jody's surge tank? Is this on his Chevelle?

No, I haven't put one on the Chevelle yet as I haven't experienced any issues. Then again, I fill the tank when it gets down to 1/2 tank or so. I did not invent the idea, just brought it up in some threads a while back as a solution that really works for fuel starvation/sloshing issues with efi.

Think of a surge tank as a really large fuel bowl on a carb............. if the pickup becomes uncovered in a hard corner for instance you do not get the immediate dying/fuel pressure drop with efi that you normally would, because the surge tank is still full. Now if you run out of gas in the main tank, then yes, the surge will fail also...........

Hmm. Interesting. I saw in the other fuel system thread you are planning to ask Hector @ Rick's about building this possibly... I am very interested in knowing if he will and at what added cost. Might cover all possible issues that could arise if that was done eh?

thanks

The Marine, Off-Road, CORR , Air Boat users require a "make-up" tank as a part of MY EFI system.

The tank is simple, a tube about 18-24 long and 3"-5" in diameter, vertically mounted.

One or two "lift" pumps (low pressure) remove fuel from the main tank corners, then into the Make-Up tank.

Fuel overflow is returned into the main tank as is the EFI system return.

The "high" pressure pump is fed close to the bottom of the Make-Up tank that includes a bottom drain for water dirt inspection.

When you feed your engine with a qualty stable fuel mass, it will treat you to a win.
