I was thinking it might rise to level of 'regular maintenance'. In the old days you could tell what the 'dirt' was on the single fiter that needed replacement. Not anymore.....

suv1, what year or years were the machines the tanks had to be swapped out?

My tank has less than 4,000 miles of fuel run through it.

Having purchased a replacement fuel pump from them, I had sent an email to Quantum about a fuel regulator for a 2016 900ace - they returned with this one saying it came up when they entered my machine info?:

https://www.highflowfuel.com/i-28317648-quantum-fuel-pressure-regulator-300kpa-for-ski-doo-mx-z-600-2004-2020-replaces-513033643.html

I did not order it though. It looks different than the one you have in your picture. Good job on the cleaning and thanks for the info.
We tried one of those this winter, it fits in the pump head but only regulates to 48psi, the sled will run but it lacks power/speed..like a plugged filter

I have checked various manuals, but can't find the spec on fuel pressure for 900ace - would you happen to know it? I would like to send the info to the highflow people - given the same engine is used in multiple skidoos and seadoos, (and maybe those 3 wheeled motorcycles?) given the demand they might come up with a new one which is correct.

We should write them an email explaining the 300 kpa (44 psi) is for the E-TEC, and 300 kpa (58 psi) is for all the SDI and ACE sleds.

I've come to find out alot of these fuel pump failures is not the pump itself but just faulty or blocked regulators, be nice to find an aftermarket regulator that fits/works?
