Does anyone know of a place that sells in Canada? I've searched around and found Whitbread Performance. I know Xman is in the UK, so im trying to find something local or a trustworthy seller to buy from.

whitbread is the way to go. I’ve dealt with him. I also bought 3 timing belt protector plate from him as well. Exact same design as original 2Micron timing belt protector plate but different color. Old one was black, this one is silver as bare color.

Canada based? That would be Stevenson tuning, he sells xman Cp3 pump kits.

Anyone have any longevity reviews on this setup? I just bought a 2014 Jetta with 107k and want to make provisions for when something stock craps out or if i can go no longer without scratching the itch. Currently just deleted and tuned both ways stg 2

Depends on who you ask.
Most people say that the CP4 design is junk.
Most people look a a CP3 conversion as a way to eliminate a time bomb.
From what I've seen, the most basic explanation to CP4 failure is fuel contamination, water, other contamination from various services and\or cracking the system open, or lack of lubricity.... (read bad fuel quality, lack of priming after a filter change, etc)
At the end of the day, they are a different design, and the CP4s are more "sensitive" to any type of contamination or lack of lubricity... the CP3s are more tolerant.

I had a CP4.1 in my Jetta that went to TDI heaven before its time. I never had any issues with it before it was taken from me ~182k
I've seen plenty of CP4s last, and I've read about many more that crapped out...... just about any outfit that takes apart failed units usually find rust (so water) or other contamination, and very few find twisted rollers, etc.

I got 209k on mine right now. Thinking i might just do the CP3 pump at my next Tbelt since im in there. Also, would a CP3 pump be a good upgrade when doing power upgrades, for example, CR170 turbo upgrade?

Just one datapoint for longevity. I had a CP3 HPFP installed on 11/8/2016 @139,848 miles. Now it's 2/8/2022 and I have 189,XXX miles, so 50K miles and 5 years and 3 months. Of course it's also true that the original pump was still good after 139,848 miles and 5 years and 7 months. So I can't say one is better than the other based on my experience, but I have felt better about things ever since I had the new pump installed.

I donated my old pump for a car that had a failure and just wanted to return the car during the buyback. I'm glad that wasn't me! I'm also very happy I'm still driving my car and I don't worry about the pump, although I'm planning to get a new Golf R in 2023. I may also keep my car for at least a while longer after the new purchase and let the new Golf R live its early life as a garage queen.

If you are diligent about your maintenance and inspect your fuel filter canister during religious filter changes, I would suggest you let it go until it shows signs of issues. We have better fuel quality up here then they do down there (as a generic statement).... now this doesn't mean that you can't potentially go to a shady station that hasn't been maintaining their tanks and potentially end up with contaminated fuel (or water, etc). Unfortunately, we don't have any control over that.

I have personally kept (and continue to do so) every single receipt from every single tank of diesel I've purchased over the last 12 years.
I also go out of my way to only fill up at a few "usual" stations, unless ofcourse I'm on some roadtrip and can't control that.
I also use a lubricity additive, which many people tell me is snake oil, etc..... (and not a good value)
In my perspective, it's much easier to absorb spending a few extra $s with every fillup, than to spring for a one time cost HPFP replacement or/retrofit that will run me $$$$s instead.

Even if you do a CP3 conversion, you're basically only making the pump more tolerant to crappy quality fuel/lubrication..... the injectors will still go to crap if you end up with junk fuel or any debris that the CP3 might tolerate..... so it's a bit of a fake security approach in my opinion.

Lastly, yes, the CP3 will outflow the CP4.1 as it has 3 pumping heads vs 1, so it will provide more fuel if you reach the limits of the 4.1 due to upgrades.

I always run some form of additive every fuel-up. It's clear that added lubricity will only help the fuel pump and system to function properly and last longer over time. I recently started using Hotshots EDT over the usual DieselKleen silver bottle I had been. Can I tell any difference? No. But it keeps me at ease knowing I'm doing SOMETHING. I always recommend it to anyone with a TDI

Fuel filters are done on every other oil change and I do those at 10,000km, so every 20,000km it gets changed with OEM filters. I also only use "name brand" stations and go out of my way to make sure I goto the same ones cause those I know are good. Plus i keep every receipt just incase. I was thinking of doing a CP3 upgrade before I do a CR170 turbo upgrade just incase I dont hit the max and cause stress on the pump.

I can't say its the exact cp4 revision pump but on the stock cr170 uk gtd's the cp4 pump handles it just fine even after a stage 2 tune.
Stick with the cp4 although CP3 is a solid choice for reliability.

I think mine is only twin piston.

GasBuddy is awesome for fuel receipts.

Pretty sure the 3 in CP3 is for the piston count. Our stock CP4.1 have one, and the 4.2 have two (and two outlets)
Would really like to hear how that unit was destroyed.

I find it fascinating that you upgraded from a modern CP4.1 "timebomb" to a "performance" CP3 from a late 90's 69hp Peugeot 206 that only had 1.4L of displacement.

CP3s can come from various models that make far less than we intend. I believe mine is from a Smart car, yet should flow enough for 300hp.
