Owner reviews for fuel filter

I opted to go with a Black Market Performance fuel filter kit. With this kit, I now use a CAT 1R-0750 filter which costs about $30 IIRC and can be bought from any truck shop in the country. As other commenters have said - the fuel filter(s) and system is not a place to cheap out given the cost of replacing a diesel engine and given the general "gunky" nature of diesel fuel, in general. Besides completely replacing the front fuel filter itself with a filter that is easier to obtain, it filters down to something crazy low. I don't recall the exact micron level but I know it was markedly improved over factory.

the donaldson P551315 off amazon or through ryder are the cheapest absolute 2 micron filters, have been running them on mine for the last 100k. Like $13/piece Much cheaper and I believe just as high of quality filters as the airdog branded stuff, perhaps superior.

Def a must for the tsi engine.. what I found to make huge diff is spark plugs and fuel filter.. They say 40k for spark plugs. I do mine every 20k and APR even says if ur tuned do it every 12-15k. I found it to be overkill.. Every 20k for 50 bucks it's perfect to keep ur car running at top peak all the time

CAT fuel filter upgrade on a Duramax is a no brainer!

I would like to add a few things I learned when replacing my filter on my old buick. First off, I would spray it down with pb blaster several times and let it soak for a good hour or so. Then I would remove the line on the other side of the filter (I think it will be rubber/plastic and should come off easy once you push in the tabs, also make sure to relieve pressure from the system using the valve on the fuel rail before opening the system) . If you use a flare wrench on the rusty fuel line fitting you will surely round it. What you want to do is grab it with a knipex pliers wrench and hold tight. Then use another wrench and TURN ONLY THE FILTER. Do NOT turn the fitting or you will surely snap the line.

Third filter change for me and not a trace of metal was found in the fuel filter reservoir. I plan to drive the car to approximately 75-80K depending on what I'm at in late 2018.

First time I bought a Bosch fuel filter and saw made in Israel I checked for correct threading & good seating repeatedly before I powered the pump to fill it.

Last item on my service list to change was my fuel filter. The one on there was changed recently and for a genuine one. But for peace of mind and so I know when next due I changed it anyway and used the correct jubilee clamp.

ok so replaced the fuel filter, the fuel that came out the "dirty" side of the filter was black and had small particles in it

It was a pain in the ass gettin the lines off with pushing and pulling etc. I had a oem filter on there. Right now I just got one from autozone for the sake of being cheap. Duralast. With my discount was like 10$ Anyway its all back in there and snug. However the return line to the engine is clipped on and doesn't move if pulled unless released by pushing the clip in. But the line from the tank can just be pulled off. It's almost as if the clip isn't functional anymore. Both sides are pushed as far as they will go. I turned it on. Let it run for a few minutes. Didn't notice any leaks.. I can't see the line just "coming off". But it can come off without pushing in the clip if pulled hard enough..
