I am in the process of putting on a Raptor 150. The problem is they do not address what to do with the return line from the fuel injectors. From the factory, the line goes to the top of the "in" side of the filter housing. There is a banjo type fitting with another fitting on the top for the return line. The raptor comes with a new fitting for their fuel line from the pump, but has no place for the injector return line. I have called Pure Flow about this and it is the first time they have ever had this problem. They have two suggestions: 1. cut off the end of the metal injector return line and put on a piece of rubber line to "t" it into the return line off the injection pump. 2. Move the fittings from the "in" side to the "out" side of the filter housing if it will reach. They claim to have sold several of these with no calls or questions, so I was wondering what some of you have done to correct this before I try it.

P.S. They claim their air dog system corrects this issue because it has the filter with the pump and bypasses the factory filter. This is where they are getting the "t" and rubber line idea from, but they do it with certain fittings that only work with the air dog system.

Thanks,
Chuck

Most people adapt the line somehow and T into the return to the tank, similar to option 1. I wouldn't run the injector return line to the p-pump without filtering it again, it accumulates a lot of soot.

If you have the pump with the filters, just get rid of the factory filter altogether. It will clean up under the hood a bunch, and will out-flow the stock filter by a long shot.
