Although the ECM definitely now not has just about anything to do Along with the injection program, it needs to be retained in order for the gauge cluster to work, as well as other items like the drinking water temperature and oil tension sensors. Immediately after measuring the size of the P-pump, Bosie fabbed up a bracket and relocated the ECM even more towards the firewall, along the driver aspect of the block.
Along with the cam taken out, the remaining gear housing bolts (6 bolts protruding to the oil pan, and 5 T40 torx bolts) were taken out plus the equipment housing itself was pulled off the motor.

P-pumping a 24-valve five.9L Cummins requires full access to the front address and kit housing in order that they can be eradicated. The catch is that the gear housing can’t be eliminated without the need of very first pulling the cam. This suggests anything in front of the engine has to be moved away from the best way.
Heading past the freebie mods, the following reasonable action is usually to Have a look at the pump’s shipping valves. The delivery valves are positioned within delivery valve holders, both of which are positioned involving the plunger and barrel assemblies as well as the injection strains that feed fuel towards the injectors.
It combines the extreme fueling capabilities with the P7100 with the upper- owing 24-valve head. This not just delivers a substantial volume of added horsepower likely to your table, it also provides with it the time-tested reliability of a mechanical, inline injection pump. For Stewart and plenty of other Cummins proprietors that’ve concluded the swap, the P-pump is the greatest point that ever occurred on the 24-valve Cummins.
And when coupled to your 24-valve motor you can get to reap the benefits of the upper flowing (4-valve) cylinder head, which implies you can run a larger turbocharger without sacrificing minimal-end drivability. Finally, there are no electronics to worry about failing, particularly the pc married into the VP44 that’s notorious for giving up the ghost at quite possibly the most inopportune time.
As with the return fuel line leaving the P-pump, Bosie customized a portion of the VP44’s tricky line, flared the top, and connected five/16-inch fuel hose. The return line tees into your manufacturing facility hard line leaving the back of The pinnacle, close to the firewall.
We’ll Take note that Bosie organized each the rocker arms and push tubes the exact same way they sat from the motor (so all wear factors would keep on being a similar when everything went back again jointly).
The lifter holders were being then removed along with the factory push tubes reinstalled, along with the valve bridges and rocker arms. After that, the PolarPump inventory entrance deal with (which is reused) was cleaned up and equipped which has a new crank seal, the supplied P-pump bracket was bolted for the block, and Scheid’s camshaft sensor adapter was set up in The brand new gear housing (demonstrated). The factory camshaft sensor should be retained with the truck’s tachometer to work.
that have been fitted with general performance-targeted timing improvement and/or grid heater deletes. Having said that, chilly begin challenges can easily be remedied with using a block heater and/or holding timing progress conservative.
When you choose into consideration that Additionally they Make some of the nastiest P7100 pumps all around, Scheid results in being a a person-halt shop for P-pump 24-valve conversions.
Opposite to what some would've you think, the P7100’s robustness, functionality and dependability You should not enable it to be uncomplicated.
As soon as the manufacturing unit raise pump no more provides adequate gasoline source stress towards the VP44 (and when it sees 0 psi for extended periods of time), the EDC atop the VP44 is exposed to Excessive heat and eventually fails.
