OP,

I used to be really worried about stuff like that when I got my first PSD. But, think of what they're designed for. They need to been worked at least somewhat. You basically want to do all your maintenance at the correct intervals, remember your payment/don't beat on it from every stop light, but have fun driving it. It likes getting to and maintaining 190-210 oil temp and 1,700-2,000 RPM for extended periods of time. In fact, it needs it, precisely for what Zeb mentioned. Let it run

Your best move would be to check and see if your auto insurance covers fuel contamination. Water and subsequent rust is your number one killer of these CP 4 pumps. If they cover it, drive it like you stole it. That chances of you having an issue are pretty slim but I understand your concern. 10k is a large amount of dough to fork over for a repair. Add that in with your monthly truck payment and yeah, it would hurt, bad.

Id Invest in a diesel site fuel filter kit before a disaster prevention kit.

Can you explain? I'm not familiar with how it works? Is it a filter that filters right out of the pump? Cause that's the only way to stop metal from entering fuel system...

I was understanding the "problem" is fuel lubricity, not filtering.

Precisely. And any filtering isn't going to help once a pump is grenading.... People don't get that the fuel used to lube the internals of the pump is directed to the injection cycle of the pump...


Fuel goes in, lubes cam and rollers, picks up metal, then goes directly to the piston to get pressurized and sent to injectors....

Bypass kit takes that lube fuel and tosses it back into tank. It only stops fuel system from being contaminated

While I don't have a HPFP to put my hands on I'm asking to gain the knowledge. I'm not trying to argue any particular point.



So the HPFP in stock form uses the same "lube" fuel to inject fuel into the cylinders.
Whereas using the Bypass kit the "lube" fuel is never introduced into the cylinders and has a secondary "clean" feed of fuel to the cylinders.



Is that the right principle of the bypass kit??


So that would leave us to using the OEM filters to capture any shavings/contamination that is "bypassed" to the fuel tank.


Is that correct?
