I had a lift pump failure a few months ago and after reading these posts have convinced myself I need to install a fuel pressure gauge. I plan to install an EGT soon and would like to do this all at once. Any recommendations on the gauges?

FYI my dealer told me that the put in an improved version, that all these things will fail....blah

One thing I noticed was after they replaced the lift pump it seems that I have to wait longer for the light to go off in the cluster prior to starting it the first time of the day. any ideas?

 

As I posted on an other thread our EMS truck is having its forth replacement pump installed in just over 60,000 miles. I advised the dealer that given the nature of our business we would not wait for another failure to occur and that we need a permanent solution even if it means us buying an aftermarket pump and mounting it on the frame. I have been communicating with Scotty on this. Now that Stanadyne set up looks really interesting. I like the idea of a lift pump and 3 micron filter combination such as the Stanodyne set up. Has anyone actually installed one of the Stanodyne pump filter units?

The dealer advised me that DC is working on a retrofit kit that puts the pump back into the tank. He also says the current pumps are failing because of worn electric motor brushes and this is cause by vibration during idle. He claims the pumps are failing primarily on trucks that have a lot of idle time which this truck does. However, since I am starting to hear of some 05 pumps failing I don't have a lot of faith in DC's retrofit kit. However the truck is still under warrantee so I will take a wait and see approach. Unfortunately, we will not be buying more Dodges for the fleet. I am already taking plenty of heat for this one.

 

Lift pump has nothing to do with the "wait to start" lamp. The time for the light to go out is based on ambient air temperature. The engine is warming up the air when the light is on to aid in startability.

Did you guys know that Bosch has a Maximum inlet pressure spec for the CP3. I believe its 16psi. We have several dynos running with 24 psi and have not had issue, but I thought I'd throw it out there. There is no minimum sped, as the Duramax doesn't use a lift pump at all and its the same CP3.
