Why does my Cummins fuel pump shut off after 30 seconds?
Why does my Cummins fuel pump shut off after 30 seconds?
Here is my reason; the factory design of the Fuel injection pump pulling/sucking fuel from the tank 40′ in front of it through a pump that shuts off after 30 seconds and through two filters is crazy, it strains the pump and it ultimately starves itself causing it to self destruct.
What are the modifications to the Cummins CAPS system?
After some intense research I have decided to modify the existing fuel system design to eliminate the root cause for the CAPS fuel injection pump failure which is low fuel pressure to the fuel injection pump.
Where is the caps injection pump on a Cummins RV?
My plan is to relocate my primary filter/separator in the fuel tank bay with the pump mounted just after it, pushing fuel down to the engine’s secondary filter then onto the CAPS injection pump.
When to turn on the pump in a Cummins truck?
There is no ECM strategy to turn the pump on when fuel volume is low, fuel flow is not monitored, in fact the only item monitored is the lift pump if there is an electrical draw, if its working or not it has no idea, it just will cause the $5500.00 injection pump (parts only not labor) to self destruct.

How much psi does a Cummins caps pump take?
The CAPS pump will accept up to 25 PSI (per Cummins), what it doesn’t need it will return to the tank with no problems. The pump I ordered is the same one the RV dealer I spoke to swears by (I didn’t want to be the test pigeon), its adjustable and the factory setting is 17PSI.
