Also, please be sure your old valve is a 9/16\" wrench!! If not, this is the wrong valve. See item #
175508995700
But please keep in mind that the valve is designed to allow some fuel to pass. Making it a self bleeding system. If you look at the ball seat close there is a tiny cut to allow this to happen. The purpose of this item is to create a small amount of pump housing pressure, not to stop all fuel flow in either direction.

\"Jason will be your pump man if you let him\"
From a Customer who Found Us on : \"Just a note to let you know that the injector pump that you re-built for me works like brand new. If there is anyone here that needs one re-built I will tell them you are THE BEST IN THE COUNTRY\". Thank You so much Ken - AZ
I rebuild and set these pumps for a living, and have been doing so for 32 years, If you would like to send me your pump to be rebuilt, contact me. Most of the pumps that use this valve will run about $550.00 for DB2 and 895.00 for DB4 to be rebuilt. We can also check and clean your injectors for free, so send them along as well. After checking your injectors, we can give a quote if any fail testing.
Here are some of things that can effect the price:
- Pump is locked up and/or the main drive shaft is broke.
- Engine will not start when warm, after sitting from 1-60 minutes. But does start when cool. This may indicates a bad head and rotor.
- Cam ring in pump is worn, requires inspection during tear down.
- Pump has excessive rust and corrosion.
- Housing is damage or unusable.
Here is how it works:
- Contact me with your pumps Models numbers.

Please Note: Your fuel injection pump is a very technical devise. Not only does it control your engine it also protects it as well. Repairing your pump yourself is a great way to save money. However, extra care must be used as serious pump and or engine damage can occur. A person repairing their own injection pump is assuming their own risk.
