In reply to: Ernie 's message, "Re: Racor Filter Change" on 12/ 26/ 09, 3:58pm

Thanks. I have two, so I run the Racor, then a primary and a secondary. I bought the part, and I am going to do the change out in a few days, and for the heck of it, I will change all 3 together so its easier to keep track of when it was done. Do you know if the generator pulls diesel through that Racor system also, or if the ONLY fuel filter the generator has is the one on the side of it?

The only thing I know about the generator fuel is that on mine, there is a smaller racor under the front bumper that supplies the generator. You can change that one, same procedure. The filter on the Perkins is a pain to refill and I have wound up priming the engine so it will fire.

Hi Stu,
Just be sure that you top off the spin-on filters on the back of the Detroit engine with VERY CLEAN fuel. Fill them to the point of almost overflowing- you can't afford to get any air or dirt in the system at that point. The Racor is a little more forgiving- it will purge air by itself if you get any in there. Like Ernie said, it still needs topped off with clean fuel too. Then genny should have a little, baby racor filter that is located up behind the right front bumper. I use 2 micron filters in the Racor's and 10 micron filters on the engine. On average, I change the Racor filters twice as often as the others. They are cheaper and easy to swap out while on the road.

Am I reading something wrong here? I always thought that the filters became finer the closer to the motor. So the larger (Racor) 10 micron filter would clear the bulk of contaminents and the smaller engine mounted filter at 2 microns, and very easy to clog, would be the final filtration stage.

I did place the little red O-ring on the T-Handle on the racor on the wrong side of the racor filter top once. Lost prime at a camp ground, very embarrising, made plenty of white smoke. Kind of like the time I didn't blow the leaves of the roof of the bus and they clogged the snorkel air intake and collapsed it.

Don't forget that some of the smaller racor filters for our generators need a free spacer installed in the filter body to insure proper filtration; a big racor factory oops as I recal.

Regards,
