Hi guys,

I put an 040 in the car a few months ago. Ran fresh wiring, new relay etc etc

Up until today, you could just hear it humming/sucking away. From inside the car you could just hear over the exhaust & from the outside you could barely hear the pump at all.

Today it has started whining/buzzing and it is significantly louder than normal. Should I be worried?

if it makes you feel better, my 040 makes a hell of a lot of noise, all the time. gurgles, buzzes, whining...

very noisy pump. car has always been fine though, been running it for a year or two now.

I don't have a gauge so I haven't been able to tell. Car seems to be running fine though.

Mate go get an autometer gauge that you can put in your engine bay they're like $20 and hook it up to your regulator, its such a cheap mod for important information if you're running more than base fuel pressure.

Check your tank for shit!

Pull the pump out and inspect it for black dusty crap on the bottom. If that or anything else is on the strainer of the pump you need to remove the tank and have it cleaned.

My 044 went this way too, exact same symtoms. Started also getting fluctuating pressure.

Ripped it out and went a 023, still never figured out why it died. Was a genuine 044 too, strainer was clean, good wiring etc.

There just getting so hit/miss now it's not funny.

I really don't think it's anything to worry about, my 044 has been like this for a couple of years now with no issues what-so-ever.

My guess as to WHY is that it's probably working harder to pump the thinner hotter fuel around. It's basically because there is excess fuel travelling to a hot engine bay and back. Standard, our cars run a control module that drops voltage to the fuel pump at idle, these tend to get removed when aftermarket fuel pumps go in.

Same with mine. Mine has a very loud buzz & grgule sound since day 1 of getting it installed when my stock one died. The exhaust noise covers the pump noise up inside the car, however outside its very noticeable when you are near the rear of the car.

Being fine for about close to a year now.

    • from an old insurance company i was with (Budget Direct) I had someone roll back into me at the lights got them to pull over. Got a picture of thier licence with address, had a dash cam video and, thier phone number. But only had 3rd party on the shitbox i was driving. insurance did nothing, cops wouldn't do anything due to the value of the damage (under $3000) so i just had to suck it up and go to U Pull It. 
    • Small Update on the Exhaust Situation A 200-cell cat was a bit too expensive for now, so I had the exhaust shop fabricate a new exhaust from the cat to the rear and an exhaust tip. I went this route to avoid cutting into the original exhaust and keep it intact. It’s essentially straight-piped, and the sound is noticeably different. The exhaust tip came with a silencer, so if it gets too loud, I can easily install it to tone things down slightly. Right now, the car bangs and pops like crazy -- which I personally love. In the future, I might add a resonator or a 200-cell cat, as niZmO_Man suggested, but for now, I’m really happy with how it turned out.  
    • And that's a massive problem, because deadshits will deadshit and give you false details. At least in these days of mobile cameraphones, it is trivial to take photos of any ID they are carrying at the same time as the 300 photo extensive documentation of the state of the vehicles that I recommend even for minor incidents. And you get photos of the person's face, any visible tatoos, etc etc, while you're at it. Then you try to avoid mentioning that you're fully capable of making explosives of various power levels and will wreck their shit if you are forced to hunt them down.
    • No, I don't remember the exact reasoning (was 20 years ago!) but the cops didn't end up supplying it to us either. Actually my mother went through a similar thing recently where she was hit when stationary, flustered and didn't get address (she got plate details, name, phone and insurance company, but not address). Person who hit her blocked her number and their insurance company (naturally) would not provide any details. Her insurance company also required her to pay the at fault premium because she did not have the address, cops did not help as it is a minor civil matter (they said their only course was if the other driver had left the scene of the accident without providing any details). She only ended up getting that refunded because they happened to be insured with Suncorp and she was with APIA so same company owners. For some reason the address is critical in insurance companies recovering money from the at fault party
    • If you're driving something like an R32 through to R34, no chance of meeting Euro4. Euro4 came out in 2006, and car manufacturers back then were complaining how hard it would be to meet those regulations. Not a chance a vehicle 10 years earlier is going to be compliant.
