I had asked for advice on this in the past-for those who may have a bad pump (Mine was a Lovett 1200) here is what it took to do the replacement:

Remove both inside exhaust manifolds on 6.2s. Remove alternator and cool fuel system on port engine.
Swear. Stand on head. Swear. Unscrew old pump. Replace with new pump.
Put Humpty Dumpty back together again.


Might be easier to just pull the engine.

My port side on my 32 has died. Had an exhaust manifold let go last weekend, so replacing both. I might have to take this on too while I have it apart. Sorry you had such a hard time, but thanks for the reminder while I have it somewhat apart.
