Fuel Hand Primer Pump Compatible With Zexel Isuzu NKR NPR NQR NRR FRR FSR FVR FTR Truck Caterpillar Komatsu Excavator HINO Mitsubishi Chevrolt GMC W5 W4 Nissan Volvo

Perfect and durable replacement for my 1984 300SD

On my 2001 npr it was peeing out diesel. Well sure enough this was the culprit. It took about 5 minutes to replace and it’s sealed up nice now.

Feels cheap. Fits my 1985 Mercedes OM617 but you will need a big (22-24mm) crows foot to install it properly. The stock on is just a 17mm. I’m still fighting some air incursion somewhere after installing. I’m hoping this wasn’t defective. Running out of other places too look.

Junk, fell apart.

Thanks

Perfect replacement for the primer pump on my Komatsu D21P dozer. It was down for the count, where it sat, until this replacement arrived.

Looks oem and screws down to seal which is a plus. The plunger however popped out after being used twice. I was able to reinsert and screw down to prevent an air leak but no longer trust its seal.

It does pull fuel from the tank to prime lines and filter, but it leaks a lot of fuel out of the top of the primer. Price was good but not to happy with the performance. Maybe this one was just faulty and I just got a bad one. They did give me a full refund so that was good that they heard my concerns.
