it will be interesting to see if members opt for the cp3 over andrew's filtration kits.
What Timk said...That would depend on the all-in price.
Agreed but from what I have read the cp3 has little chance of failure. Possibly more peace of mind than just containing the swarf.What Timk said...
Though I think that if you don't have plans beyond stage 2 then the stock pump and andrew's kit will cover most folks
Stage 3 or higher? get the CP3.
If you can sell the old HPFP and fuel pump for about the same price as CP3 and adapter, then it's only the labor cost which I'd consider cheap insurance.Agreed but from what I have read the cp3 has little chance of failure. Possibly more peace of mind than just containing the swarf.
Timing belt change would really be dependent on if you are near your next change IMO. I had just changed mine 20,000 miles ago, so I didn't change it. But, it can't hurt of course. And yes, timing belt tools will be needed. Lock the crank and camshaft. No more having to lock the HPFP, thoughPerfect! Plug and play makes it even easier.
Are you guys doing the timing belt when you're going in there anyways, even if it's not time? Does install require the timing belt tools?
.Are any software updates needed when the CP3 is used? My guess is no, but I'm curious.
The kit was originally designed to work 100% with all the factory equipment. Let's move this discussion over to here:Just a question, but does installing this CP3 pump, have any bad or good effect on our damn emissions components, for those that still have them?
The CP3 has been around for quite a while and it has been used in many (bigger) diesel engines. The biggest difference between the CP3 and our CP4.1 is that the CP3 has 3 pistons instead of one. Therefore, it can pump more fuel with shorter piston strokes. This has several advantages and at the top of that list is reliability. It has been a rock solid performer in many engines running on crappy American diesel fuel. It also pumps more fuel with less engine power, plus the pumping strokes do not have to be as precisely timed with fuel injections. It appears to be (pretty much) "immune to the hand grenade failures".Sorry for the ignorance, but what is CP3 pump and is it immune to hand grenadine failures like the stock HPFP....
I looked at Andrews experimentation thread.... still who makes it, what was the original application and why does VW not use it?
