[V8] Newer Cummins Dodge - NAC

[Dave Head]

Check with BD-Power. I believe they have an aux lift pump to correct 
this - long time known issue.

After some calling around and troubleshooting, I've come across a common problem which is considered to be a design flaw. How bad, you ask? A local (Las Vegas) Diesel shop does 5-6 repairs a month on these. To the tune of $2800 each.

It is electric, and as it dies, the pressure to feed the injection pump is too low, Through this continued low pressure, the injection pump goes bad. That's the big expense. The "transfer pump" is only $190 at FLAPS. THe injection pump is the big expense.
