Better yet...just stick a magnet in the housing and see if you get any metal. If it's present, besides the inj pump, you will also need to replace the lift pump...that's where the metal came from.
those are usually the rusted metal flakes, the shinny ones are alum. from the injection pump. here is the run down on what it will cost to fix it at your local gm shop.
injection pump 1798.00 + 6.1 hours
lift pump 162.96 1.0 hour
fuel filter housing (complete) 213.00 1.0 hour
drop tank clean lines 150.00 to have tank boiled + 5.0 labor
injection pump gasket 2.00
intake gaskets 35.00
15 gallons of diesel + stanadyne performance formula (20.00) added to fuel to get warranty on pump
fuel injection nozzels are 80 - 120 depending on how much your parts guy likes you
glow plugs are about 30.00 each pull the turbo and knock it all out at once,
turbo remove heat shield, 4 15mm mounting bolts to manifold, 8mm band clamp bolt ( losen up exhaust at flange makes it easy to install) air outlet hose and braket. soak the manifold bolts the night before in heat riser penitrate to make removal easy.
when you pull the fuel return lies off be very carefule with the clamps they are 3.00 each, put a dab of greese in the ends of the return lines and push them back on with the clamps in place or you will be hatin life
on another note we just droped a brand new 6.5 in a 95 1 ton, her bill was 13,000 and some change

have a nice day
