One other thing I forgot to mention is that you might be pumping too much fuel for the regulator to flow and properly regulate the pressure for. I hope your using something like an SX billet reg that uses -6 fittings, and not some pissy sard regulator.

wen the pumps makes there noises the car isnt even started its wen i just arc out the relay to make them pump aka first thing no heat involved. i got rid of the fpcm because im using a gtst harness with a gtr computer was just a cheaper option with the conversion ive done, to much hassle to make it work just run to ground etc. both pumps have a one way valve infront of them. im not a f**kin idiot so dont treat me like one..... and no i have a turbosmart fpr1200 with -6 in and -6 out....

Wow such a friendly guy, and when I was just thinking about digging out the schematic for the FPCM wiring.

Good luck with your problem.

ive got the schematic i dont wanna run it thnx neways GTRNUR.... im just asking has neone had a similiar problem with joining 2 pumps into a y piece then into a 1/2inch (-8) fuel line christ ppl is it really that hard of thing understand..... this is the reason y i never post question on this site cuz i get f**kin stupid replies and no information.... may aswell just bang my head against the f**kin keyboard..

i tend to agree with SirRace, GT-RZ & GTRNUR...u wont get your answer on this thread - sometimes these things get outa control! the joy of forums :action-smiley-069:

the reason u wont get your answer i think is because nobody has 'hands on' experience with running 2 044's on 1 line hence diagnosing your problem is anyones guess

i went ahead a ran two line one for each pump same thing..... only when both pumps are on and the fuel pressure actually increases when the 2nd pump is switched one.... i had it sitting at 40 just for test purposes and when i switched on the other pump it just to about 45..... also the noise will go away wen i decrease the fuel pressure down to 30 and below psi..... wat do u guys reckon? im stumped now.... it also stats to get pulsations when the pressure is turned up thinking maby that the fuel damper may be a needed item

Seems the turbosmart reg cant flow enough fuel, so the spring is oscilating and causing the pulsation. You could try running the largest return line size you can get, and just have it return into a drum for testing, save you runing new lines on the car. If that fixes it then fit a larger, or 2nd fuel return line. Failing that try a diferent regulator. Ive used the aeromotive billet regs with success, identical design to the SX regs.

but how could i really flow nemore then wat can come out of the single -6 from the centre of the rail..... im gonna wait till the car is started and see if the noise is still apparent with the car actually using sum juice

all figures point to that and i dont wanna have to fork out for another reg..... and these things are rated for 800+hp of flow..... the sx regs are $395 and they claim they also help as a fuel damper to stop chatter.... but ill still be running a -6 line so wont this still have the same effect?

im not bad mouthing the reg yet cuz thats the last thing i wanna change..... could it be that the -6 line just wont flow enough therefore will increase the pressure itself due to being a restriction?

plus also wat i didnt mention is the reg has 2 inlets but im only using one.....

yep, easy fix would be to stage the second pump to come on arount 10 psi boost. The increased rail pressure reducing the pump flow combined with the fuel demand from the injectors will significantly reduce the flow through the reg

yeh thats the problem i havent wired them up this way.... i just have the 2nd pump on a switch so when i feel im gonna stand on the throttle on the higher boost levels i just flick it on and then wen just cruising round just leave the one running as to keep the fuel temps down... or try neways. i dont have a fpcm running the pumps so i cant wire it in through that either.

Your using an R33 GTR PFC right? The output signals from that ecu should still be able to be used to control a second pump. Sure you wont have the FPCM, but you wont be needing one anyway. Basicly they are a solid state (transisitor/mosfet) relay anyway... If you have an R33 GTR circuit diagram its pretty easy to trace the wiring back to what pin on the ecu you need to steal a signal from.

yeh i got all the wiring diagrams etc.... all sounds good in theory but how would i program it to kick in and out etc

plus the part that i just cant seem to understand is wen i have both pumps on if i wind the pressure back down below 30psi it doesnt make the sound...... nethin above the noise comes back.... as if a damper is needed....

    • You just need to remove the compressor housing, not the entire turbo. I would not be drilling and tapping anything with the housing still on anyways. 
    • So, I put my boat on a boat. First of all, I'm going to come out and say it. Why is Tasmania not considered a holy goal, an apex that all road-legal modified cars go to, to experience? This place is an absolute wonderland of titanic proportions. If people are already getting club runs for once in a lifetime 30 person cruises to Tassy then I've never seemed to see it. It is like someone replaced the entire place with an idyllic wonderland for cars, and all of the people living there with paid actors who are kind, humble, and friendly. Dear god. After doing a lap of almost all of the place I've found that it's a great way to find out all of the little things that the car isn't doing quite right and a great way to figure it all out. All in all, I drove for 4 hours a day for a week and nothing broke. I didn't even need to open the engine bay. This is by all means a great success, but it has left me with a list of things to potentially address. I also now have a 3D printed wheel fitment tool which annoyingly hasn't got any threads in it to actually assemble it. I might be able to tape it together to check the sizing I actually want to use, but it'll likely involving pulling the shocks out to properly measure travel at least at the front, and probably raise the car while I'm at it, at least in the rear. I scraped on quite a few things and I'm not sure how else to go about it. I was taking anything with a bump at what felt like 89 degree angles. And address those 10 other tasks. And wash the car. God damn it is dirty. And somehow, the weather was perfect the entire time - And because I was on the top of Mt Wellington it turns out it was very much about to freeze up there. I did something I typically never do and took some photos up there in what must have been -10 and the foggy felt like suspended ice, rather than mere fog. If you own a car in Australia, you owe it to yourself to do it.
    • Damn that was hilarious, and a bit embarrassing for skylines in general 😂 vintage car life ey. That R33 really stomped. Pretty entertaining stuff
    • Hi, I have a r32 gtr transmission. Does any of you guys have an idea how much power it will hold with the billet center plate and stock gearset? At what power level and use did yours brake with or without billet plate? Thanks, Oystein Lovik
    • Saw this replica police car based on a Mitsubishi Starion XX parked next to a 'police box' (it's literally a box) in Hirohata, Himeji City in Hyogo prefecture the other day. It's owned by Morii-san who is a local Mitsubishi Starion enthusiast. According to a local radio station blog post, he always wanted to make a police car himself based on ones he saw in his favourite Manga comics.  As it's illegal to modify a car to look like a police car and drive on the road, Morii-san tried many times to get permission from Aboshi police station headquarters nearby. They refused initially by after they got tired of that they granted him permission. However, the car can only be displayed on private property and obviously can't be registered as long as the police livery is present. The car was completed at a cost of 1.5 million yen (US$ 10,000) in addition to the car cost. A location was chosen outside Hirohata Police box where the car can easily been seen from the street. Morii-san has two other Starion road cars, both widebody GSR-VRs.
