First of all-sorry for starting so many threads guys. I'm new to the AATV sport and bursting with questions. Maybe it's better to keep posting all my questions in one thread-dunno.

Anyway, my Hustler has had an electric fuel pump added (I assume its not factory equip). It's wired to the ignition switch so that whenever the key is on, it runs. I don't like that cause I can't work on amything else that requires key on without disconnecting the pump. I'm thinking about putting a switch on the dash to power pump on/off without key on.
Also wondering about how this engine (18HP twin cyl Briggs) handles electric pump as fuel supply without any regulator. I've not driven it a lot, but it seems to run Ok this way and has no issues so far.

Have any of you guys been down this road before? Love to pick everyone's brain and take advantage of previous experience.
