what do you mean by your old pump is having trouble?

have you considered running new wire to the old pump to up the voltage it gets? im not sure if that is what is causing your pump to play up but its worth changing anyway especially if you go and put an 040 pump in. there are heaps of threads on how to do it around this site.

my a/f has dropped a little bit so its running leaner. we checked the voltage going to it and thats fine. The pump just doesn't pump like it used to.

Yeah i have read the tutorials they seem really good. I'll source a pump and get onto it.

glad I found this was about to start a new thread.

So for a stockish r33 (as mentioned above, just breathing mods std boost) with this cause it to overfuel or use more fuel than the factory one? would the 040 be the best choice for a near stock car? also what sort of power could it support roughly?

the fuel pump can NOT make a car run richer unless the old pump was dead and not supplying enough fuel. replacing a working fuel pump with a new fuel pump that has a much higher flow rate will make no difference at all to the amount of fuel being used, etc, as that is all controlled by the injectors and fuel pressure regulator. all the pump does is supply the fuel. any extra fuel that isn't used is simply pumped back to the tank.

I replaced my stock fuel pump with a Bosch 040 when the stock one died up the a**... no change on fuel efficiency.

One thing I did notice was that the Bosch was much louder compared to the stock pump, I can hear a high pitched whining sound when its working while I'm outside the car, however my exhaust noise covers it up once I get inside.

      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.

      I presume it would take more than just slapping a big modern catalyst on the exhaust? It's interesting though, looking at the old sales brochures and listings it does not mention anything about emissions. No one cared.

      Yeh nice, looks like their part of keep it reet? Will have to swing past. I'd much prefer someone actually look at my car and custom make a part, then get a generic part online and hope it works.
