I did the same thing on one of the company's earliest CUCV purchases, an
M1010 amb, after getting some good advice from our diesel rebuilder to not
bother toying with the manual pump if it's suspect. Strange thing is, after
installing the electric pump - and solving the hard-to-start problem - I
*then* discovered that the reason it was hard to start in the first place
was due to a cracked steel line where it leaves the frame-rail on the
pass.side around the wheel-well.
The rebuilder fellow told me not to leave the old hulk of the manual pump
cycling away on nothing but air for too long, and to replace the pump with a
blanking plate that GM evidently sells (seeing as though the latter 6.2's
and 6.5's supposedly all have the electric pump anyway.) You'd probably
want to remove the frustrating little steel piston that operates the pump
lever as well, just in case it somehow winds up somewhere it isn't supposed
to (though that may be impossible - better safe than sorry.)

(and you've just reminded me that I've forgotten to do exactly that on the
damn 1010)
