I thought they were standard on all school buses. I have a Racor 900FG, but its current replacement is the 900FH. There are plenty of Chinese knock-offs of them on eBay, but I'm not altogether convinced that they're going to be cheaper in the long run . . .
Whatever you get, it's going to be better than blowing the tips off the injector nozzles and possibly trashing the engine.
