Hi Guys, Just came across another Bosch authorized VP44 pump rebuilder - here is the link. http://www3.jasperengines.com/blog/2011/12/02/jasper-remanufactures-vp44-diesel-injection-pumps/ The link shows the actual "diaphragm" that is installed in these pump that fails regularly - so Jasper claim. Anyway, I just thought that this link might be of some interest. Thanks

Already in the list of rebuilders... http://articles.mopar1973man.com/2nd-generation-24v-dodge-cummins/25-fuel-system/247-bosch-certified-vp44-injection-pump-rebuilders But what's odd is that diaphragm... I still to this day can't find it in any Bosch Documents. http://articles.mopar1973man.com/2nd-generation-24v-dodge-cummins/25-fuel-system/437-bosch-vp44-injection-pump-exploded-view

I personally wouldnt trust jasper to work on my lawn mower. I have installed a couple engines from them and had nothing but problems

The steel insert has been standard rebuild practice for many years now. And the fact that they're using the old fcm and simply doing a reflash (also standard practice for the builders who don't install new electronics) would steer me away from them being they are the most common part to fail.
