Just to temper JS's advice a wee bit..... if you opt for the mechanical
pump, choose it wisely. I have experienced fuel pump float at high rpm....
The pump lever can't follow the pump cam and fuel volume will go down. One
very good thing about mechanical pumps is that when the motor stops, the
pump stops. Electric pumps "should" have some kind of Murphy device to shut
them off in the abscence of oil pressure or rpm..... (think 'can't get out
of the wreck and the fuel pump is still running'....). I like the safety of
the mechanical pump but the consistency of a good electric is hard to
ignore.

Yours is relatively mild compared to some of the grenades I've tried.....
and most of them lived quite well with mechanicals. Watch real close to see
if you're nosing over downtrack or through the traps.
