FS110a how to upgrade to pump version
 

I have purchased 2 of OS 110 alpha with out the pumps. Yhis was prior to the pumped version comming out.

What I would like to know is how to upgrade it to the pumped version and if this is possible.

I have looked at the OS web site but the parts listing doesn't specifically list a Pump.

Can I purchase just the pump? and what is the part number?
Or do I need the pump and a new Carby. If so what are the part numbers.

I would also like to do this for a Alpha 72 for a another project.

Thanks

To convert the non-pumped engine to the pumped version, you'll need:

OSMG2511 44982000 CARB 61P FS110A-P US$144.99
OSMG4157 44907030 COVER PLATE FS110A-P US$23.99
OSMG6501 44969430 INT MANIFOLD FS110A-P US$25.99
OSMG2200 72508100 PUMP PD-08 FS200S-P US$89.99

These parts can be ordered through any hobby retailer who sells O.S. Max engines and accessories.

Thanks Bax.

I had suspected I may need the pumped carby as well as the pump.
