whats the best cheapest tank to use for a daily driven 09 wrx? i do not track the car but i go to tge drag strips once in a while...

what tank fits best in a hatchback?

[johnmx3ze]

i was looking at the non baffled tank but edgeautospprt told me they were back order?

do you know anything about it? when will they be back?

[Aquamist]

Checkout these people

[johnmx3ze]

what size is a good size for a daily driven car?

[Aquamist]

The unbaffled tank is available from here. I believe our US importer is reluctant bring in the unbaffle tank as it is not cost effective in small batches.
A 5L tank should last about 1-2 gas fills.

oh I see why now, shipping to Canada is more than the tank itself...

that too bad I would of bought that unbaffled tank, ill look on the usplastic site for a 5l tank

thank you

The system is checked and the faulty item is the flow sensor cable. Failure could be due to heat or a small section of the cable was squeezed, probably by a cable tie. Pm me your shipping address.

Richard, I have the Aquamist 15psi cracking pressure 4mm inline check valve. How often does it have to be cleaned? Do I clean it the same way with the Aquamist jet?

[Aquamist]

You don't need to clean it if you use Dmin water. Worth opening it up and check the components.

making slow progress, got a new pump, works perfect
however the system still doesn't respond, and I have a feeling my FIA2 unit failed

This is how I have everything wired:



Symptoms:

1. orange failsalfe LED doesn't turn on at all (even when ignition on it should light up for 5-10 second and go off, it doesn't happen)
2. green LED light on the FIA2 doesn't blink with the engine running (notice in my wiring diagram I am feeding FIA2 external PWM signal from autronic, but I also tried connecting the green wire directly to the injector PWM wire out of the ECU with no effect)
3. I took apart FIA2 and tried to check the LED lights for continuity, results are:

- no continuity between any of the 4 legs of both LEDs
- the only response I got was from the left leg of the red LED with one of the connector pins, all other legs didn't respond to any of the connector pins



FIA2 dead?

[Aquamist]

The system will not work if you left the both black wire ungrouded

[Hyper]

both which?
I only left one black wire coming out of FIA2 disconnected

my pump works and primes, system builds pressure and stops in the ready position once the desired system pressure is built

Perhaps just the one. It has been a long time. I believe the same black wire is grounded at somewhere else. You have the original diagram.

[Hyper]

I grounded the black wire from FIA2, so the only disconnected wire now is purple which I know is fine



didn't change anything, green still doesn't blink with engine running

I did notice though whenever I touch the ground with that black wire, green LED blinks once

right now I am even more confused, any additonal diagnostics I can do?

[Aquamist]

1. Keep the black wire grounded.
2. Remove the green wire from the fuel injector and ground it.
3. Now ground the green wire, does the green led stay on?

[Hyper]

fixed it, thanks Richard
I am not certain, but I have a feeling my vampire taps didn't cut deep enough through the cable plastic
I ended up using my PWM user controlled output to drive the green wire

also, in case anyone would need this info - 2D system with 30cc accumulator, priming pump (windshield washer pump) and 1mm jet is spraying approximately 400ml per minute

[Aquamist]

Good news indeed.

Richard got the flow sensor today... It's totally different than the one I had before. And was all my other stuff shipped separately? The gauge the FAV and the module?

Post a picture of the part received, can't remember what I sent. This is a red harness shipped separately.

I was working on a new surge tank today and run into a problem, I only had brass fittings but no matter how much I tried to gluegun it to the little plastic tank, it kept leaking



what kind of fittings do people use to connect main and surge tanks? I do have some spare pushlock fittings but they are for 4mm hose, I don't think it will feed the surge tank fast enough

[TheSTIEvery1Knows]

This is what I received and haven't received the rest of my kit yet

Sorry first picture was not the one I selected.

The rest of the kit was sent before this connector.

[TheSTIEvery1Knows]

Really that's not what I want to hear. I haven't seen it yet :-(
