Wes, do you have a fuel pressure guage? Did it act up before it failed or did it just crap out.

TIA

That knocking is air in the fuel lines and rails and not enough fuel to the injectors. Cycle the fuel pump several times before starting. That will help purge the air out of the fuel lines and rails.

I have had several Bosch go bad on my truck. I have not had a failure with the Airtex E2236. I recently purchased a spare Airtek to keep in my truck like many of you do a spare cps.

What kind of mileage did you have on these Bosch fuel pumps before they failed?

Less than 60K. Do bear in mind i run my truck on vo (my fuel), perhaps Bosch cannot handle it.
That also says alot for the durability/capability of the Airtex E2236.
