After all of the injector paranoia, I decided to get a secondary filter. I could not get a frame mounted filter since I also have a Supertank that fills all empty under frame spaces.

I found a kit at GCL diesel in Edmonton. Cost was $299 CDN installed. Was very impressed with the clean install and the modular nature of the Stanadyne system.

Would have liked a bigger filter but this seems to do the job. Also need to adjust a little to move filter away from PS filler cap.

Those are pretty slick units. You can get filter elements between 2 and 150 microns. I have a head I purchased from Caterpillar, that needs the top cap, or one of the many accessories that you can get for that head, such as primer pumps, fuel heaters, etc. Someday I plan on putting it ahead of the frame mounted Cat filter, to catch asteroids, boulders and small planets before the fuel hits the IR0749, with a 30 or 150 micron water catcher.

Hey if one is good, two is better!http://www.dieselplace.com/forum/smileys/Big Smile.gif These are great units.

Diesel Dad, more info please. Pre or post OEM, and how may microns. I'm trying to find more info, myself.

The filter is pre-OEM and is 5 micron altho you can get a variety of filters for the same head. Here is a link to the Stanadyne site that list lots of goodies for this system: Stanadyne (http://www.stanadyne.com/dsg/dsg_dffs.asp)

hasselbach.............I love your plumbing job! http://www.dieselplace.com/forum/smileys/Cool.gif I run those fuel lines on my race car. If people only knew how affordable and effective those lines are, once they're on, they're on; no clamps necessary.


BTW, are these pre filters really necessary? I mean now with the extended injector warranties, it seems like were only prolonging the visit to the dealer for warranty replacement.

Thanx, Diesel Dad. Will look into it some more. How much are the filter elements?

BECAUSE, the longer I can keep Mr. Goodwrench out from my hood, the better I feel... If I can prolong the replacement until after I trade the truck in, I'm a happy camper.http://www.dieselplace.com/forum/smileys/HiHi.gif

Regarding the Stanadyne elements, I called Stanadyne a few months back and they told me they were working on a frame rail FM100 kit for the Duramax. They were also planning to add a 10micron element to their line up. I'm currently using the FM100 with a 30micron as a prefilter (http://community.webshots.com/album/77018086bLHHHC) along with the MegaFilter but if the 10um became available I would switch. Also, Reliableindustries.com (http://www.reliableindustries.com/inv/stan/1_fm100.php) has good prices (have to call) on Stanadyne products.

Hey, Diesel Dad, went to the local dealer for Stanadyne stuff. Did some askin about the set up.... came up with more questions.....sorry. Did you get any electronics with the unit (water in fuel sensor, fuel heater) Also, the filter itself, is it a spin on, or does it use a locking cap style (push on and twist, to lock)
The Stanadyne dealer (also Racor) seems to recommend a Racor unit, over the Stanadyne. About the same dollars for both ($500 Cdn), then add WIF, and heater.
I do like your set up. Easily accessable, check and see if there is any water in the filter, ease of change, without crawling under the truck.

$500? Wow, is the exchange rate that much of a difference between Canada and US? I paid $160 for each of mine. Call Reliable Industries.


The only concern I would have mounting the lift pump high near the engine is that pumps work much better pushing rather than pulling liquids. I would be concerned about pulling vapors out of the fuel which is something we are trying to prevent.

Opps. Forgot to mention installed. Just also had a thought. If the second unit is before the OEM, then you really don't need a WIF sensor, or a heater.

DIESEL DAD: JUST PUT THIS UNIT ON (FRAME MOUNT). I SEE YOU PUT 5MICRON ON I WENT WITH 2MICRON. WHY NOT FILTER AS TIGHT AS YOU CAN, AM I MISSING SOMETHING? GOING TO HAVE TO CHANGE 2MI. A LITTLE MORE OFTEN I KNOW ,IS THAT THE ONLY DIFFERENCE?JUST TRYING TO LEARN, CAN ALWAYS GO UP TO 5MI. THANKS

Max Owner: no WIF or heater. Could add them later if needed (as well as a lift pump). The head is push-and-twist to change filters.

Bruce: it just came with a 5 micron filter. Could go smaller later. Just changed my OEM fuel filter after about 20K kilometres and it looked clean as new.

Frame mount: why would anyone want to mount a filter on the frame where it is a PITA to change and where it is susceptible to rocks, dirt and ice ? I don't get it on this one.

The guy at the place I was at, says the twist type are prone to falling off, if not properly installed. Said a few other semi negative things about the Stanadyne filter, but don't remember what they were. He recommends a Racor set up.
Like anything else, the more people you talk to, the more difference in opinion.

Well, on the other hand, not sure of the advantage of having a quart of diesel fuel directly over the left exhaust manifold, not to mention the amount of shaking that filter must receive being mounted directly to the engine.http://www.dieselplace.com/forum/smileys/Dead.gif


Diesel Dad, I thought your Stanadyne had a lift pump installed in the unit like mine? If not, I bet you will see that the filter is probably only 25 to 50% full due to the vacuum pulling air out of the fuel. Heck, my stock filter showed banding that equated to about 50% usage prior to the installation of lift pumps. Edited by: hasselbach

Diesel Dad: My filter is on the frame because it filters fuel as it is transfered from 50gal in bed tank down to oem tank.(transferflow system) Built steel box around it for safety. I only fuel up into in bed tank so fuel in oem tank should be pretty clean. Will know when I cut open filters next oil change.
