Original Fuel Pressure Regulator:
Fuel rail without FPR:
Original FPR adapter:
Measurements I made quickly:
Malpassi Rising Rate FPR (1:1.7), bought 2nd hand for 50€:
The hose is going to be connected to the adapter:
Suitable adapter = SRA01 (69014) for Nissan:
Or this one:
The blue fuel rail adapter is for Nissan (http://cgi.ebay.com/ebaymotors/ws/eBayI ... K:MEWNX:IT) and the piece that fits into the fuelrail needed 0.1mm to be sanded of in diameter and 0.4mm in lenght to fit in the hole of the fuelrail.
The OEM fuel return line was hard PVC, so I had to cut it and attach a 8mm rubber hose to it that goes to the Malpassi.
To fit the Malpassi, I found a convenient place at the back of the intake manifold. Drilled 2 holes in the aluminium and fitted the FPR.
For the rest, it was easy...
Original OEM plastic fuel line with GM-connector:
OEM FPR:
Malpassi Rising Rate FPR fitted at manifold backside:
I cut off the 8mm (outer diameter) PVC original fuel return line and shove it into an 8mm (inner diameter) rubber fuel hose, secured it with 2 fuel line clamps:
Some more pics:
After a first testrun it noticable that throttle respons is quicker and mid-range to high-range power has increased. Also any dead spots have disappeared. I've yet got to fine-tune it but the first test results are promising... It's now running at 3 BAR, I think (previous owner set it to 3 BAR, he said). Got to give the screw a few turns clockwise (+) to see if it makes a difference...
