If its time to replace your worn, tired high pressure oil pump (HPOP) and you are not in need of additional pressure to support performance injectors or a chip/programmer, these are a great, drop in stock replacement pump. Featuring a one year warranty, you can have confidence these will last you as long as your original pump.

Please note that an Early 1999 model would indicate a SuperDuty built prior to 12/7/1998.
