Accelerated Performance's Fuel System Fix for the BRZ/FRS/GT86

[Calum]

Why not go with a surge tank setup with an external pump? Just for the extra flow?

Because that doesn't fix the fuel flow issue inside the tank!

A surge tank setups take up room, smells and is pretty loud.

Basically anyone just popping on a surge tank really hasn't taken a look at the real issue with the fuel system.

You can backpedal well enough in 2nd and maintain forward movement. Once you get the hang of it its easy. 3rd usually sticks as long as you get the momentum right.

The first thing we had was a surge tank. Unfortunately that doesn't work well.

The factory tank has a crossover pulsation siphon system. The larger flow pump throws that system off. That is primarily one of the reasons people are seeing a starvation problem in corners.

The surgetank relies on the primary system to fulfill its requirements. If the primary system doesn't keep up, your surge system falls off.

Example

2 Pumps in a surge tank for High HP Systems. Requires a 2 Pump lift system to provide an adequate amount of fuel flow over a duration of time. You either need to have a large surge tank, or have enough flow to keep up with the demands of your consumption.

Ok so now we've got 4 pumps in the system. All of them are relatively expensive. We've got an additional enclosure full of gas to kill you in an accident and just another place to leak. Ok Great!


So now lets say you have a 1/2 tank of gas and your considerably below the hump in the primary tank. The pulsation pump will not keep the primary side of tank at an adequate level with the two pumps to keep up the flow to fill the surge tank.

So what do you end up with here. We end up w/ a system that costs considerably to much. Can't run very low, possibly a fire hazard and has flow issues under cornering.

if this can hold 3 044s I would buy it today.

Why do you need 3 044s?

This, I understand. Thank you for taking the time.

i use to have an 044 on my past project, way too loud, i would never do it again

How are these pumps hooked up? I'm assuming one is going from the drivers side to either the other two pumps or to the front as well?

*sigh* gonna hold-off going FI...

There are 3 pumps not 2. 2 Supply fuel demand and the other is "Magic"
