Started noticing a diesel leak coming from the lift pump housing on my MX-13 along with surging when my tanks got low. I didn’t want to risk running my high-pressure pump dry and blowing up a $4k fuel system. Motorspares Direct got this pump delivered directly to my shop in two days. Bolt-on fitment was smooth, no leaks, and the engine runs silky smooth now. Excellent service and fast delivery!

Customer brought in a 2015 Peterbilt 579 complaining of power loss on highway grades. Checked the fuel delivery volume and found the old pump wasn’t meeting flow specs under load. This 1939435PE pump was an exact match down to the port locations and mounting seals. Swapped it out, primed the fuel system, and took it for a loaded test drive—pulls hard with zero fuel starvation or pressure drops. Genuine PACCAR quality at a much better price than local dealer markup.

We had a 2016 Kenworth T680 with an MX-13 that was taking 15 seconds to catch on morning cold starts, accompanied by intermittent low fuel pressure codes under heavy haul. Diagnostic tests confirmed the original lift pump was losing prime overnight. Ordered this genuine PACCAR 1939435PE pump from Motorspares Direct. Freight shipping was fast, installation took under two hours, and the truck now fires up on the first turn of the key. Fuel rail pressures are right back at factory spec. Zero core hassle makes buying here a no-brainer.
