Add some oil to the fuel and hope for the best? There is no getting around the fact that a rotary pump in a V-8 engine has to do MUCH more work than an inline pump.
At 2000 RPM - the one set of pump plungers in the rotary pump have to fire off 8000 times in one minute for an eight cylinder engine.
Take the same V8 and put an inline pump onto it - at 2000 RPM and each pump only has to fire 1000 times. That's a huge difference.
Besides that - an inline pump has no distributor section to wear out - and that's the #1 issue on the Stanadyne pumps.
Here's a part of an article from National Defense Magazine from July, 2004.
"Army Ponders New Diesel Engine for Humvee Trucks," notes that maintenance nightmares have been experienced in Iraq because engines regularly break down and often must be replaced after only 1,000 to 2,000 miles of operation. Much of the blame for this is placed on the bolted-on armor protection that adds weight to the vehicles. However, the inability of the rotary-distribution, fuel-injection pumps to operate satisfactorily for sustained periods of heavy-duty operation is probably a contributing factor, especially when low-viscosity fuel is used in a hot environment. Interestingly, the fuel-injection pumps in many, if not all, of the HMMWVs operating in Southwest Asia have been retrofitted with Stanadyne's Arctic Fuel Conversion Retrofit Kit. This kit apparently has done little to offset the significant increases in maintenance that have been experienced recently. Rethinking the SFC Combat operations that occur in higher temperature environments certainly will intensify the operational and maintenance problems of diesel-powered vehicles and equipment with fuel-lubricated fuel-injection pumps. Since almost half of the Army's diesel vehicles and equipment have rotary-distribution, fuel-injection pumps, a solution is urgently needed.
