I have a perry pump I plan on putting on a ST-90K. I am doing this because I want to put the fuel takl over the CG of the pusher Jet I am building. I started to set it up according to the instructions I got on the Perry web site. It shows a back fill line set up on the fuel system. It wants you to install a T fitting between the pump and carb and run that line back to the line that feeds the carb right at the tank. I thought this was not right so I called Perry for some help. He told me that diagram on the web is for a car setup. He told me to use a 3 line setup on the tank and run that line from the carb back to the fill line at the tank. This made more since to me and this is how I have set it up. I was hoping to hear back from some of you on how this setup works

The "Loop" system works very well for it supplies fuel to the carb that is basically not under pressure. The advantage is that a regular carb will still work pretty much the same as it did in the old suction manner.

Thanks for the feed back. So the loop back to the fill line is the correct way to install the back feed line.

The "Loop" set-up is actually the most trouble free way to install a Perry pump

If you look at that setup in his diagram the loop setup feeds the extra fuel from the carb back into the feed to the pump. I thougt that was a mistake so I called Perry just to ask that question. He said that diagram was for RC Cars and not RC Airplanes. Perry said the loop on airplanes goes back from the carb and into the fill line for the tank. This made more since to me so that is how I have set mine up. I was hoping to hear from someone else who is successfully running the perry pump with a 90 two stroke and see how thiers was setup

I always set up a three line tank and the return was the third line.

They used to have a line diagram and it showed it better.

OK it looks like a three line tank with the fill line having a "T" fitting in it with one line going to the tank to fill it and another line going to the carb over flow "T" fitting. This would give the Tank a fill line, a out put to the pump/carb and an over flow to provide static pressue. No pressue being used from the muffler. I hope I have explaned myself correctly.

Jim, take a look at the Walbro carb adapter you can get from ken Lambert. If you placed a pumper carb it should work good...as long as you use the right kit in carb. Capt,n

Say jstanton, I would be interested in how your Super Tiger 90 performs as I'm considering purchasing one myself.

Fact is, I would be interested in comments from anyone on the Super Tiger 90.

Thanks,
