RE: DA-50-R
Hi WLJ,
The two easy ways to dot are, cut the pulse hose and insert a tee fitting, giving you a connection for your B&B pump. The second is to remove the aluminum pump cover on the carb with the pulse fitting. Drill and tap it for a 10-32 pressure fitting. This will give you a connection for the pump. I guess you can also tap the insulator for another fitting provided that there is enough material for threads.
