Thanks for all the replies guys, much appreciated.
The pump has 4 pressure fittings on the back, I'm not sure if its the hanno mod or not - maybe Jeff can chime in on that one. I'm not running a check valve anywhere, should I be? The documentation I have with the motor lists it as the 61-RF and it uses the PA-102 pump (I guess thats the RF-P?). Thanks again for helping me figure this out!
No check valve...
Yes it's a standard RF-P (non Hanno)...The PA-102 pump has the four nipple arrangement and uses the Type 86 carburetor...The o-rings which I listed above will be the correct ones... (remember they are silicone o-rings so no petroleum based products around them at all!!)
Replace all those o-rings shown and you should see a vast improvement...I would not worry about changing anything on the pipe length until you have the carb o-rings swapped out...It's not running right so you can't tune the engine in it's present state...
