I have the stock fuel filter setup on my bus, strainer then pump then filter. I've been reading about all-in-one systems from Racor and Davotek that have water separators, priming systems, and so on. should I change my setup to something modern, which one, and where do I plumb it, before or after the pump?
Thanks, Brian
I have an older Racor in place of the primary, before the pump. It has the filter element (30 micron) in the top housing, and the clear bowl at the bottom with drain valve to take the water out once in a while. It has a 110 v. heating element wrapped around the outside of the housing for preheating the fuel before starting. And an internal 12 v. element to heat the fuel while driving. I rarely use those features because I don't drive the old Courier 96 in the winter. I got the thing used and it came with the fancy electrical doodads. I still have the secondary 10 micron filter after the pump. The whole setup makes the bus run so much better, LOL, in my mind!

Brian, why would you want to change you can buy a lot of filters for the price of a fuel pro and they are not maintenance free.
I have one in the shop I would make you a deal on, if you have spin on filters save your money and spend it somewhere else.
I don't know what engine you have but you need the right flow I have seen people buy off the E place only to find out the filter didn't have enough flow for their engine.
On our new Freightliners with DD engines, Davco has made the 482 series just for that engine. When used, it increases the engine mounted fuel filter change interval to about 100,000 miles. Not only does the Davco get the water out, but because of the upside down design with the filter bowl on the top of the filter, there is no question when the filter needs replacing-eliminating premature filter element changing, or waiting too long and having a fuel starvation situation. It works where-as the filter gets more dirty, the fuel raises in the bowl. Finally when the fuel reaches the filter change line, you change the filter. It can come with heaters too. Because of its' design, it does not have a primer pump available. But with the hand screw plug at the top of the bowl, you can prime the engine with that-I have done it several times with trucks at the dealership. Davco is a great fuel/water separator filter. Good Luck, TomC
