I can't find any information on the procedure used to change the filter on this model. I used to have the smaller model Racor that had the oil filter style scew on filter and the thumb
wheel primer on the top. I know how to work this one, but the 500FG looks much different.
This one has a large metal T handle looking thing on the top. What is this for? Is this a prime
pump, is there an integrated primer
pump on this model?
Does the bowl unscrew from the bottom, the filter drop out the new filter pushed up and then the bowl screwed back on? OR
Does the top come off, the filter pulled out from the top and the new filter droped down into the unit?
Is there a bleed nut on this model?
I am sure that I can figure out how to get it unassembled by just trying things, but I would rather have some up front knowledge so I don't make too much of a mess.
