While the 24-valve 5.9L Cummins found in &rsquo;98.5-&rsquo;02 Dodge Rams can be a great workhorse engine, it leaves much to be desired in the way of reliability and horsepower potential. A failed lift pump tends to take out the electronic Bosch VP44 injection pump, the rotary style pump itself can&rsquo;t fuel past 4,000 rpm, and as of late, ECM problems seem to be plaguing the &rsquo;98.5-&rsquo;02 second gens. After encountering the latter scenario&mdash;where the engine would spontaneously free-rev on occasion&mdash;the owner of this &rsquo;01 quad-cab &frac34;-ton, Thales (T.J.) Stewart decided he&rsquo;d had enough of the VP44 woes. But instead of trading the truck in on a newer common-rail, he elected to ditch the electronic rotary unit in favor of a P7100 (a.k.a. P-pump).<img src="https://magarticles.magzter.com/articles/4757/389942/5def9f3620fac/1575984865651.jpg"" owidth=1205 oheight=805" style="height:401px; width:600px" />For both street and competition applications, P-pumping a 24-valve has long been thought of as the best of both worlds. It combines the extreme fueling capabilities of the P7100 with the higher-flowing 24-valve head. This not only brings a considerable amount of extra horsepower potential to the table, but it also brings with it the time-tested reliability of a mechanical, inline injection pump. For Stewart and countless other Cummins owners that I&#39;ve completed the swap, the P-pump is the best thing that ever happened to the 24-valve Cummins.<img src="https://magarticles.magzter.com/articles/4757/389942/5def9f3620fac/1575984865464.jpg"" owidth=602 oheight=416" style="height:416px; width:602px" />Thanks to Scheid Diesel, the process of hunting down all the parts needed for a P-pump swap is a thing of the past. Aside from the pump itself, the company&rsquo;s P7100 conversion kit comes with everything you need to add a P-pump to your &rsquo;98.5-&rsquo;02 24-valve. With one of Scheid&rsquo;s bench-tested, 215hp 12mm pumps topping things off, this 16-year-old Dodge effectively went from under-powered to a force with which to be reckoned.
