That is where mine is located, in the baggage bulkhead.  It's never a problem, at run up, or in the air.

Colyn,
 
For the 300 series only.  A stuck pressure switch, hmmmm.  In these complex airplanes few will have a dedicated breaker for the pump relays and it can be a problem when pulling any multi-use breaker.  If one thinks about it long enough, a fuse for the relay power placed after the pump breaker will suffice with the added benefit that pulling the pump breaker removes all electricity from the entire hydro-electric mish-mash, thus resolving any power related problem.  Then again, some have probably followed the Lancair instructions to place the pump breaker on the baggage bulkhead - failing to remember John Denver's reach behind experience.  
 
Blue skies,
