Default Fuel Water Separator update

Hey fellows,

I met a BBer in an 86 the other week in our campground. He was showing some of his coach upgrades. One thing he showed was a different type of fuel water separator. Check this out and let me know what ya'll think. He said that it could not loose it's prime at all. I think it was something that Parliament add for him.

Last year I let Florida Detroit Diesel/Allison service my bus right after we bought it and they mentioned to me a filter upgrade they could install that were in Prevost busses. This one may be it because they mentioned you had good visual indication of the filter. The part number in your thread is for the element only though, see attachment for the complete filter. There is an internal check valve at the inlet, so that's the reason it will hold prime. Filter element FS19763 is rated for 7 micron particulates. You can get the complete filter in various configurations depending on the application. I did a quick search and the complete filter unit is pricey. The Racor filter is a good unit and by changing the filter element quickly I have never lost prime.

My mechanic suggested changing mine out for a simpler filter too.
For some folks, that may be the right filter.

For me, nothing compares to the Racor.
On my last trip, I could see my Racor need to be changed by the dash gage. In a RV park and in 5 minutes I had it changed. Yeah Rick S helped a little.
If you happen to get a bad load of fuel, you will be glad you have the Racor.

My mechanic had trouble loosing prime on mine, I know why.
The is an O ring around the twist handle and seal on the Cap. One grain of sand can cause a problem and cause a vacuum leak. Take the time to clean and lubricate these two seals and fill to the top with ATF and you will not have a problem. Filter choices at 2 micron, 20 micron and 30 micron.

While I certainly don't think I would trash a Racor to get one of these. (But if you do I will buy your Racor)

For the Cummins guys it might be a good solution as mine only has the one standard spin on filter with no provision for WIF or any visual indication. (you can drain it from the bottom but that's it.)
But then there is that $400 price tag thingy ....
It does look like a great setup!

Was out looking at the bus for another project scheduled for today and I looked at the Racor while there. I never noticed it before, but I believe BB installed a check valve in the fuel supply line on the inlet side of the Racor filter to preclude drain back to the tank. See the component in between the two 90 degree fittings, don't know what else it would be without removing it. So unless you are sucking air from a o-ring seal on the cover handle as Mallie indicated and if this component is a check valve, then no need to upgrade filters just to gain that function.

Just put a Racor 1000 in front of that little filter and check valve mount--I did before i started running mine--

Had Racors on the previous two coaches, but I really like the Davco that is in this coach. Easy to see when it needs changed, easy to change, and if I remember correctly filters are $10 or so at NAPA. And remember, the secondary spin-on filter is eliminated, so just one to buy and change. Coincidentally, just yesterday in Abilene I changed it, after running 7000 miles on the old one. Certainly not worth taking a good Raycor off for, but if buying fresh I would go with the Davco.

I don't remember who it was, but an expert lecturer at WOG a few years ago informed us that a 2 micron main filter left nothing for the secondary to do. He suggested using a 20 micron Racor and a tighter secondary filter.

That would be true with a 2 micron primary filter element. From what I have read, Detroit Diesel specifies a 30 micron element at the primary Racor filter and 10 micron at the secondary spin on filter location. This is the filter configuration I use.
