Nitto Oil Pump External Feed Fitting - Nissan RB25DET / RB26DETT / RB30 - Skyline / Skyline GT-R (R31–R34) / Stagea (WC34) / Commodore (VL)
A shorty fitting that lets you add an external oil feed to a Nissan RB oil pump for better oil delivery into the pump. You can run it alongside the internal feed from the block, or on its own with the internal feed blocked off.
Choose the fitting to suit your pump. The cast pump version converts the 1/2" NPT port to -12AN; the billet pump version converts the -10AN port to -12AN. Both have a 15.6 mm internal diameter.
Note: Installation by a professional is recommended. Engine internals must be measured and set up by a qualified engine builder.
Features
- Machined from 4140 hex bar
- -12AN outlet with a 15.6 mm internal diameter
- Screws straight in where the inlet-side plug was
- Run external feed only, or internal and external together
- Fits within the factory air-conditioning layout with minimal modification
Warranty
Nitto parts are made for racing and off-road use. Check every part during assembly and blueprinting, and contact us before fitting if anything measures out of tolerance. Nitto will repair or replace a defective part at its option, and any modification voids the warranty. Full terms: Nitto limited warranty (PDF).
