85 5kt fuel pump

[DGraber460@aol.com]

Just acquired a really clean 5kt. I'm much happier with it than I expected to 
be. It drives great. What should max boost register? It only goes to 1.2.
The fuel pump is buzzing loud enough that it will get some attention soon 
(probably tonight).
There are 2 noises coming from the area of the fuel tank. One is the buzzing 
I'm familiar with for fuel pumps and is constant. The other is louder and 
intermittent. Is that a normal failure mode of the pump, or is there 
something else in there I should know about before diving in?
