I just did the fuel pump on my series 1 r33. I did not see a rubber ring which i expected to find somewhere. I assum it sits between the black screw off ring and the white Plug underneath it which has the fuel lines and connectors on it?

Should there have been a rubber ring here.

The only rubber was the seal that sat around the inside of the hole. I just tightened the black screw on\off ring down and the fuel system seems to pressurise fine..

Another pump i've heard is really good is the Nippon Denso High Flow Fuel Pump, i've searched everywhere for one and manged only to find Tweakit.net who are very very over priced, also a workshop in melbourne Chasers sell them around $300 i think... apparently the tomei and HKS pumps are based on this denso pump (not 100% sure)

This is the link to the pump, not sure if anyones used them but apparently they hold big HP and are direct fit (not like tomei)

It's the rubber seal that sat around the edge of the hole when you removed the white plastic unit.

1st time i took mine apart, mine didn't move so i didin't see what the big deal was.

....2nd time (1 hr later as car wouldn't start :D ) it popped out with the plastic unit.

Went back in ok though.

Cheers man,

I was visualising a big O-Ring like seal somewhere. Mine is correct then.. :D.

Another thing, If I mounted a walbro pump in the same position on the bracket as the stock pump, will i still be able to drive the tank down till the fuel light comes on.

I noticed the walbro filter\pickup is only about 1/3rd the size of the original and sits at right angle to the pump which makes it hard to get it to face down deeper into the tank when pushin the pump back into position. I am pretty sure i got it facing down the right way.

Just FYI I am slightly under 1/8 of a tank on the stock gauge and still going. I am planning to drive it down as far as possible, Hoping to see the fuel light, this will confirm how far u can drive your fuel down using the walbro pump and filter.

    • Ok interesting i guess ill wait till using a manual gauge before making assumptions.
    • Not in any way a logical conclusion. Also, looking at those logs, I struggle to see how that much oil pressure can go away that fast unless you are sucking air into the pickup. Meanwhile the ECU voltage is chucking a huge wobbly which seems to be tied to the throttle position. 100% throttle results in decreasing voltage. It's a mess.
    • So didn't get around to installing a manual oil pressure gauge and then decided to take the car for a cruisey drive to a cars and coffee and brought the laptop along with to get another log using more gears to see if its an oil pressure issue under acceleration or after. this log has 3 gears of WOT where as previous had 2 and the oil pressure dropped once on the brakes, and the same again happens here which is interesting as it shows it can hold oil pressure while under acceleration but once slowing or just the lower RPM after a pull pressure drops. I will be chucking a manual oil pressure gauge on to confirm but so far this makes me feel it is not an electrical issue. Something else i realised is the pressure sensor also is giving temperature information and the temp stays steady the whole time which makes me feel like the sensor itself is showing a true pressure reading.
    • LOL.... fk...   there goes 25K to make 200kW
    • For sure the later RB26 variants had a different setup (6 cam voltage sender?), but the RB25DE/DET share the same ECU pinout/PCB footprint, and at the ECU plug it ends up being 'throttle sensor in' & 'throttle sensor out' (to A/T TCU) ...you stick a multimeter on these pins and you'll find them directly connected (0 ohms) ; I had an pair of Nissan ECUs on the bench long ago, and I noticed this throttle sensor in/out link, actually linked to an op-amp ...which was unpopulated on the NA board, but present on the T board and I went 'ah-ha!' in some moment of clarity... ...it wouldn't surprise me if they changed strategy here though (in the software and actual monitoring of this signal), because they did with other stuff (A/T signals).. and 0.45v as a trigger point makes sense, as that's what the external TCU units expect at idle ; kudos, thanks for that insight...I suppose it boils down to whether or not Consult can display real time data of that signal's voltage... ...in any event, it presents the same target...ie; rotate TPS unit to achieve 0.45v to suit both ECU&TCU, and where do you goto from there? Just disconnect TPSwitch connector and/or that plus TPSensor connector....or do you go for the throat and disconnect IACV solenoid and see if it still stalls? (probably throws a recoverable fault code and goes for default idle strategy?)...
