Did you make or extent that box to fit those 2 gauges?
Helps to have a friend that's a welder/fabricator. Cut the end off, then bent some heavy sheet over the top of it to match, was just large enough to get the Hewitt Industries gages in. Had to angle upwards a fair amount so they could be seen.

Bolt pattern is larger on the P. You will need the pump and support brackets, fuel lines and their supports/isolators, injectors, gear housing, pump drive gear, maybe the drain line for the injectors, supply line from the filters to the pump, and the return fitting....maybe.

The above pic is of a Ford/Sterling cabover, Ford called them Cargo. See where the intake horn bolts to the intake manifold cover? The C in the 900 series is aftercooled. The afercooler takes up the entire space where the intake cover is bolted on the above engine. The fuel lines on the above pictured engine will not fit on an engine that is aftercooled. One COULD convert the aftercooled engine to charge air cooled, but there are things that differ hardware wise. The cylinder heads on aftercooled engines had a different swirl factor cast into them. Incorrect swirl factor can cause black or white smoke or both, low power, incorrect/un even cylinder burn temps, melted pistons.

The MW pump came about before the P pump. There weren't too many aftercooled, P pumped C series engines made. IIRC there were some engines made around 1998-2000 timeframe that were off road engines and still mechanical, Cummins had the 1st gen ISC for on road around 1998, so they moved the on road emission technology to non road, which included the P pump, but those were mostly stationary engines like pumps, chippers, grinders. Things that had no "ram air".

I have a Bosch P-7100 “P” pump, gear, supports, intake cover, and injector lines, as removed from a 300hp 8.3L Freightliner FL70 if somebody has to have it. Won’t let it go for cheap though. The pump alone gets up to $900 used on eBay.

Hi Will !!! Awesome to hear from you. Hope retirement has been kind to you.

Is there a larger turbo that can be swaped out for better HP?
I swapped a small hx50 onto my truck and it was too big. The power band on these trucks is small to begin with. Adding a larger turbo alone, will only hurt you. There needs to be additional modifications done to support more air and fuel.

I suggest installing gauges and then adjusting your pump settings. It will make the truck feel much stronger just adding some fuel.

Also on the other hand, I know of a guy who put a BW S366 on his truck, with some pump modifications and the truck pulls much better than stock. The HX40 on the truck is a good turbo. Lots of guys make over 400 hp on them all day.

What kind of boost are you pushing. Did some pump mods and I can get 39psi from just that and a air filter mod
