If I may chime in here...

I have done exactly what you'all are talking about.

My local Bosch rep doesn't sell bushings. He sells a rebuilt
body(Cleaned and new bushing already pressed in and fitted to what
looked like a new input shaft, otherwise bare). This goes for $110. Then
the gasket/seal set was $27.

The lift pump is indeed a honed set, but even with worn bushings, the
lift pump is probably still in good shape. It more or less floats on the
main input shaft, so the wobble isn't directly transmitted to the vanes.
The plunger assembly as well isn't directly connected to the main input

And yes, you have to dismantle the entire pump to get at the bushings.
It took me a full week to dismantle, clean, and layout in order, all of
the parts. And another full week to put back together. Afternoons and

Now, having your local mechanic do all of this work and charge only $100
for labor would make me a bit nervous. These pumps have to be absolutely
clean when assembling. The internal parts have extremely close
tolerances. Unless he has a grade "a" clean room established, I'd be
careful here.

All in all, it is not a hard job to do, you just need to be meticulous
and have steady, very steady hands.
