FAQ

Q.  If I send in my original pump assembly can I get it back as a "completely refurbished" fresh pump system including new pumps (both LP and HP), which "service" do I select to accomplish that from your website store? 

A.   It would be the $475 Service.

Q.  If instead I opt for purchasing a "previously refurbished assembly" does it include "new" or "refurbished" OEM LP and HP pumps?  

A.  It includes New Aftermarket LP and HP pumps.  It is too expensive to buy the OEM (HP=$300 and LP is only available integrated in a new assembly)

Q.  If I opt for purchasing a "previously refurbished assembly" has all of the internal black paint been removed?  

A.  Yes, the paint has been removed from the fuel chambers.  I do recommend checking and cleaning your Fuel Pressure Regulator screen for a few months as debris in the fuel rail may still be present.

Q.  How much do I get back for a Core Refund.

A.  $50 for Fresh Water used and $0 if it is not salvageable.  Note: I am not accepting saltwater used or Aftermarket assemblies.  Please email me before sending in cores.  I will send you a label

Q.  If I opt for purchasing a "previously refurbished assembly" is the complete assembly OEM (Volvo/Carter) or aftermarket?  

A.  The assembly is OEM and the LP and HP pumps are aftermarket  

Q.  Is there any advantage to refurbishing my original pump assembly vs just buying one of your "previously refurbished" assemblies? 

A.  Depending on which "Ready to Go" assemblies that you choose it may save you $25.  Some customers just prefer to have their own assembly refurbished.

Q.  My HP pump is whining, what things can I check to try and correct it?

A.  The HP pump is whining because it can't draw fuel or it is struggling.  

1. Start at the fuel tank (is there fuel).  Trying running the system off a gas can (bypassing the fuel tank)
2. Anti-syphon valve (possible replacement, not common)
3.  Check the supply hoses for kinks or decay
4.  Fuel filter (old or new)
5.  LP electrical connection (did it come unplugged, are the contacts corroded, is the connector hot or melted)
6.  HP electrical connection (are the contacts corroded, is the connector hot or melted)
7.  Fuel Pressure Regulator (is the screen clean).  Clean with Carb Cleaner
8.  Injectors (RPM's low under power, can you get higher RPM's in Neutral)
9. Check the fuel pressure on the HP and LP sides

Q.  Does the Fuel Pressure Regulator Screen filter debris before reaching the Injectors?

A.  The FPR is offset in the fuel rail and only controls the pressure.  It does not filter debris before the injectors.  It is a good indicator of whether there is debris in your fuel system

Q.  What Fuel Pressure am I supposed to have on the LP side?

A.  Specs say 8 +/- 4psi but 16psi seems to be the norm.

Q.  What Fuel Pressure am I supposed to have on the HP side for Port Fuel Injection?

A.  Fuel pressure gauge should read 344-413 kPa (50-60 psi) for 4.3, 5.0, and 5.7 models and 248303 kPa (36-44 psi) for 8.1 models. 

Q.  What Fuel Pressure am I supposed to have on the HP side for a Throttle Body Injected system?

A.  A pressure regulator is located in the throttle body. The regulator is a pressure operated diaphragm valve. This valve reacts to fuel pressure only. Pressure at the injectors during cranking is approximately 30 ± 2 PSI (200 ± 13,8 kPa).

Q.  What can I check to see if I have a potential paint problem in my fuel pump?

A.  There are 3 things that you can easily check:

           1.  Pull your fuel pressure regulator and check the screen for paint debris

           2.  Pull your fuel filter and check the seat on the upper assembly for paint damage

           3.  Pull your HP pump (this can be done while the assembly is still mounted to the engine) and check the screen for paint chips and debris.
