Additional fuel filtration / injector replacement poll

2009 1-ton extended cab.

Don't plan on doing anything except add lubricity agent to the fuel and regular OEM filter changes.

I fuel from my bulk tank, and logic dictates that if I were put a high-efficiency filter anywhere... it would be at the pump. At least that's my thinking.

Good logic indeed. Add a good dessicant breather/filter on the vent also. 99% of my fuel comes from my storage tank these days. If I make a long trip I add my 90 gallon aux tank which usually gets me home.

FPPF Total Power in all fuel run through this tank. I buy Amoco Premier straight #2 non winterized whenever possible. I usually end up with a load of #2 winterized each year, but if I can I buy straight up and treat myself.

Hey bigchev what kind of turbo do you run and what brand of tranny do you have?

2002 Chevy Silverado LTCC, SB,

Added Racor RS60s filtration post OEM, at 20,000 miles.

Original injectors, 132,000 miles, they're not as quite as they used to be, but still run great.
Never had any kind of problems, starting, running etc. Love that truck.

ROI, supposedly the filtration is down to about 2 microns so I don't expect any problems from particle errosion. I'm sure this has already saved GM some money on replacement of the injectors, next year come July it will be my nickle if they go bad. I jus think its an investment in assurance of continued top performance. I've always maintained my vehicles like I was going to walk out of the house in the morning and drive straight to New York without haveing to check anything first.

Side note: By the way JBPLOCK, you said SWR said the wear was 6 to 7mm size, that's not millimeters obvously, you ment microns right?

UPDATE FOR 2010-Had to do 8 new injectors at 160,000 miles on my nickle, waited too long go get in on the warranty. Truck runs better than it did when new, actually idles smooth now, it never did before. I suspect I may have had a bad injector right from the start at idle and never knew it since it was my first diesel, I also suspect that by the time 20,000 miles went by without additional filtration it was on the way to failure before I got the additional filter installed.

I suspect the mileage will drop a little from the original, but there's no scientific way to blame it on the injectors because of the ULSD which was not available during the first couple of years of the truck's life. I still love it. I would recommend extra filtration to anyone who like me wants to keep the truck for a long time.

2006 K3500 - went 166,666 miles until requiring injector replacement. Bone stock, fuel filter changed every 10-15K miles. Fuel sourced anywhere/everywhere across the US and Canada, Howes, FPPF, other name brand fuel conditioners run about 50% of the time.

No added filters
215000 on original injectors
Loved it till all #### broke loose now not so much
I heard from a chevy mechanic that his friends lly went 1 million miles and motor never touched ?

2009 K3500 - Crew/Long SRW

285,000 miles on original injectors and going strong. No additional filtration, lift pump, etc. Fuel sourced at random pumps all over the US and Canada. Fuel additives run '...more often than not' but not one brand. Those used including Howes, Power Service, etc.

Due to constant towing, the total gallons of fuel run through this pump and injectors could easily be 80% more than typical - i.e. lifetime MPG is probably between 11 and 12mpg.

Go figure that one...

'01 LB7 in a 2500 HD P/U, nearing 440K miles.

OEM injectors lasted ~185K miles. On the 4th set now which I installed myself (along with new feed tubes to the injectors).

Added a 2nd filter as a primary, a Kennedy lift pump and a CAT UHE filter conversion on the OEM head somewhere between the 3rd and 4th set of injectors. 4th (current) set of injectors are still running after ~75K miles. While I smell a heavier odor to my exhaust now, balance rates are still within spec (worst is about -3.4, in Park, on cylinder #7), but it's not smoking at the tailpipe. Yet.

I use a Fleetguard FS1000 filter as my primary just after the tank (and before the lift pump), and use a CAT 364-5287 UHE filter before the HP pump. (In retrospect, I should've purchased another OEM filter head with the heater and used that with the primary as extremely cold weather leads to my primary clogging.)

Did it help? The benefits may be intangible, given that the replacement injectors for the LB7s are of lesser quality and just don't seem to last like the originals. But, any extra life I can squeeze of of them is a plus to me.

Purchased a 2020 LP5 and wondering if anyone knows if they have improved the fuel filtration on this versus the older ones. Noticed GM has located the fuel filter close to the fuel tank underneath the truck.

400400 miles on my stock 06 K3500 LBZ, original injectors, fuel from everywhere..fuel filter changed when I received a “change filter notice”..mostly ac delco filters. I’m keeping my fingers crossed.

[EdHale]

I change my fuel filter every 10,000 miles, have replaced 1 injector at approx 170,000 miles. Currently have 211,000 on the clock. Use Baldwin filters and have since the first filter change.
