obtaining fuel pump pressure

[dewdo]

I know this has probably been covered before, but should I check the fuel pressure at the pump, or at the injection pump. If it is taken at the injection pump, will you get a different reading from the pressure taken at the pump?



Will the installation of an additional pusher pump void the warranty?

anything you add to your truck could be used to void your warranty if Dodge believes that what you improved led to some failure of there equipment. I don't know about measuring fuel pressure at the injector pump but on the top of my stock 99 fuel filter housing there are two fittings-one is okay for pressure before the filter and the other for after filter. I don't see why you would need any other.
