wasnt that the malpassi one ruby ? Ive had them die a few times on the RB30 and now keep a spare wreckers one in my parts box..lol

Yep. Malpassi. Are they commonly known to die? :P Are they repairable/rebuildable?

Guess I'll be removing it and putting the Nissan one back on.

Edit:

I've done a search and come up with nothing about common problems, except some can split the diaphram. From the sound it is making, I believe the fpr is holding 60psi (should be on 38-40) as fuel is leaking internally into (I assume) a split diaphram. Once full of fuel the noise stops and the pressure drops to about 25psi = one f**ked fpr?

Trying to find out more info. Google is not my friend.

Its only $40 buy it now Damo.....get it man as your into that sport

Has anyone here installed a Bosch 040 fuel pump into a R33 before? I got so far then got stuck....couldn't actually get the pump and bracket back in the tank. Looking for some help from someone that knows what they are doing.

I have a Bosch 040 currently installed in the car but thinking of upgrading to a GTR fuel pump....

does anyone know how much power can/will a GTR fuel pump support???

the pickup on the GTR one is better then the 040.....on tuesday i was having some issues on the track....had 1/2 tank of fuel and going around the kink on the back straight at mallala the car cut out.....simply no power nothing....and then when the car leveled off it came back to life....same thing happened after the hairpin and coming onto that little straight before the S's.....so blaming it on the fuel pump.....

what else could it be? slightly worried now

if you had half a tank, it aint the pump, unless its mounted too high.

Well thats what i am thinking.....i havnt refueled yet so will be interesting to see how much it takes....i am thinking of switching to a NISMO one that has better pickup......what else could be the issue of the car cutting out twice on the one lap.....on the run the fuel gauge drop dramatically but when i pulled into the pits it was showing that i had 1/2 a tank?????

I know the Stageas have a little 'anti-surge' type sealed craddle the pump sits in. This little craddle is filled with the returning fuel from the fpr. Does the Skyline have something similar? If the pump is suspended low in the tank with no anti-surge device, you may in fact be experiencing fuel starvation ... especially under track conditions/speed.

I dont think the skylines have that ruby....correct me if i am wrong please.....but i do think that what i experienced was in fact fuel starvation....now i am begining to think that a NISMO replacement will be better as its close to what the stock one is.....ie pickup and mounting....also does anyone know what power will a NISMO fuel pump support oh and the price...just really want to get that bit sorted out for the next track day

just make sure the filter is clean.. scott had this problem with his walbro..

was mounted too low and the pump would pick up shit off the bottom and clog the filter.. car would stall and run like shit..

cleaned the filter, moved it up a little and was fixed..

try this?

they are widely used in massive V8's and drag cars cos of the sheer volume of fuel that they can deliver. their website is not particularly helpfull CARTER FUEL DELIVERY i'll try n dig moar up for u

..::edit::..

the smaller ones make great lift pumps. the rotor guys love em

which model fuel reg do you have ruby ? they have 3 or 4 models for EFI, some, stock replacement, rising rate, racing hi pressure ???

I would suss you can rebuild the regulator diaphragm and spring rates, but doubt you would need that... the nissan one fails when they get older believe me...lol ,

this is what the regulator looks like inside

you could go this route

Sard fuel regulator

or this one for the 260

Nismo fuel reg

just to throw it out there, carter fuel pumps are tits! they have a massive flow rate:pressure ratio and they are reliable as the sun

hmmmm I would go elsewhere , being from USA where Carter is a cheapo brand , and in my past V8-V10 days I wouldnt go for one

they tended to get bad flow rates on hot days , and would vapour lock easy since the pressure would get too low. a royal pain in the ass

but to each his own

have not seen them vapur lock with the rotory vane ones. but i have only used them on a 186 with a 179 head, and the rolla

    • Power steering is probably because someone has nuked the HICAS CU and you no longer have the variable power asist doing what it is supposed to. How much boost are you running? You are aware that any more than 10 psi on the stock ECU is just asking for it to go to full R&R (that's Rich & Retard, which is effectively Retarded and Retarded!) which kills all the power. Depending on the exact conditions, it can just be runnign on the fat and stupid end of the maps, then the conditions change, you make a little more boost and the ECU goes into panic.
    • @BuiltNotBought Just as GTSboy said.   If you want driveabilty and more low down torque..keep the stock runners. They are VERY good from a factory. I have them too on my RB25DET NEO and as a GTSboy i have fmic but with stock piping route(i have Blitz intercooler) Iam making around 320 BHP and the car pulls "hard" from like 2,5k all the way to 7k. I have it dyno tuned to mimic N/A power curve and making little less max torque due to the smallbox tranny. But driveability is very great. I had 350Nm below 3k so car feels very quick.   EDIT:  Not my channel but i saw this and i know that is what i want (and i have exactly this)  
    • Looking to sort out a couple of issues on my skyline  It recently was rebuilt, however rebuilder long story short did not give two flying effs about the work he did. So moving forward it's running but I have two persistent issues 1) it has a misfire / lag type of issue (was at higher RPMs but I had a dead piggy back ecu removed which improved it) now it's not as bad but still does it at random, I thought it may have been a boost issue I'm running an older turbosmart dual stage controller, turbosmart told me to try running off gate pressure however it still has a lag at random times. It has New MAF, maf plug, coil packs, sparks, CP harness.. injectors tested and cleaned. Factory ECU. 2) Power steering issue. It is tight as anything. Flushed power steering, rebuilt my pump because the bearing was shot. Flushed again still tight (mainly when parking and going slow into my driveway etc)  No kinks in hard lines, replaced the lines I could see had cracks. Still tough to steer.  I was told to shim a coin and place into the solenoid plug? Is there anything else. My steering angle sensor also has a issue. It's a used one I replaced, does it need to be calibrated? I feel like I've tried everything and this car is my voodoo doll.   
    • Holy shit... wow!!! I totally missed this
    • One main filter. Each tank has a prefilter to keep rocks and small children out, then the big main filter that also does water separation. Clogged the first one so bad it was like a rev limiter at 3200rpm. Literally just like dropping the throttle off and maintaining rpm!
