Does anyone make a replacement bucket yet for our fuel tanks and these bigger pumps? Zip ties and 2 out of 3 clips is a tad ghetto. Just a tad

Update: My fuel pump imploded on Sunday. So now I need to order a new one, turns out that was the root cause of all the fuel issues I'd been having with the car.

An aside - Lots of shops will say that you need to change the pumps to make HP. Not always true.

My tuner told me I needed a new pump and when I started having issues he said that he's never actually maxed out the stock pump. Kinda pissed me off.

I've heard around 250whp is where it runs out of juice, but I have no confirmation of that number.

Considering your not replacing the clutch or injectors. I don't disagree with your tuner. 200-225 ft/torque your clutch likes to slip and disappear.

Save your penny's

Do it the right way to avoid huge headaches in the future.

Here's the relevant parts list
FA20 Club Turbo kit @ 7psi spring loaded BOV
AEM Meth injection kit 50/50 mix
AEM 5210 310lph fuel pump
Stock injectors
Perrin full exhaust
Omni 3 bar MAP sensor

Running on 94 octane

There's your problem(see bold)

, especially if the tune was done by FA20club (the original tune that your tuner used and tweaked).

Take a look around the forum at what a nice rep FA20club (both the man and the kits) have gotten. Anyways GL with that and I hope you find what (all) that is wrong with your kit/engine. I will pray for your car it needs it

. Buy quality parts next time is my 2 cents (fa20club is cheap/poor quality to start with and you got it used)

The tune was a custom tune used both on my car and the car it came off of, tweaked for each.

I did my research and knew FA20Club was a useless vendor. I bought the kit because of how well it ran on the car it was on before, and I knew the seller. I did my homework on the kit. The installation could of gone a bit better, but you gotta learn somewhere.

My mistake was in the pump. I rushed myself and didn't get the right one and that has been the cause of the majority of my issues. I thought it was the pump from the beginning and it ended being the issue.

^^ That's fine dude just felt like yanking your chain a bit. Hopefully everything will go smoothly from now on for you.

Glad you found out a cause for your issues and hopefully the last one. This is why I mentioned the diagnostic tools in my first post - you would have seen a funky dip in the afr whenever the pump was acting funny causing you to run lean. That would have let you know that you fueling and/or ignition issues.

Update: Finally got the replacement pump in under warranty, and the shop couldn't get it to go in. Out of frustration I said throw the stock one in and I'll deal with the pump later. As it turns out, the stock pump is holding the AFR perfect through very heavy loads where the AEM one was leaning out. It's still early, but I'm optimistic that this is solved now. Hoping to get it retuned and into storage all prepped for next year before it starts to snow.

For anyone else looking into FI, the stock pump runs fine on my tune at ~250whp on 94 gas and 280whp with meth injection.
