The OEM Fuel Pump Hanger Assemblies have been discontinued by Nissan for years now. While the fuel pumps themselves can be replaced with plenty of aftermarket options, this does little to address the issue of the hanger assembles failing. In fact, after 30+ years, we are seeing even low mileage examples exhibit more and more problems: the level sensors go bad, the TT's relief valve fails, and the plastic venturi assemblies crumble away.

Thankfully, we have discovered full OE replacements from V12THROTTLE, who makes similar products for a myriad of classic vehicles. While these are not original Nissan products, we feel these are the next best option. So here's the rundown:

• Compatible with 2+2 (Non-Turbo Models)
• Includes a new fuel level sensor & float assembly
• Direct plug-and-play with the factory harness
• Compatible with factory FPCU
• Premium zinc-plated steel construction
• PTFE coated 14awg wiring

Our Experience & Recommendations

Like with any aftermarket product, there are always slight differences to note, compared to stock. Because of the complexity involved with these assemblies, we tested these on a few of our personal vehicles here at CZP, and here are some observations we made:

• The internal wiring is 14awg, which is enough to power the Walbro 400 series pumps. The underside of the pass-through terminals use a simple eyelet and nut holding it in place, which makes it a breeze to swap in a different fuel pump connector for alternative pumps.
• The lower pump bracket accepts a standard Denso-style pump, so common pumps like the Walbro 255, Deatschwerks 255/300, and AEM pumps will fit perfectly. Any with a larger lower base (like the Walbro 450 or 525) will require that bracket to be trimmed or modified.
• The level sensors have small tabs that act as stoppers to keep them from going up or down too high. We noticed that it's POSSIBLE for the stopper tab to catch on the side of the sensor assembly when moving upwards. However, it's not really possible for the float to go too high in actual use, so we think it's a good idea to trim or clip that little stopper tab to prevent it from catching in use.
• We tested the sensor calibration and confirm it matches the OEM sending units, both by comparing our measurements to a stock unit, and comparing against the values in the factory service manual to make 100% sure they are in spec.
