Aim is right.
I got mine from Harbor freight for $19. Make sure you have good sockets and extensions, because the bolts on the starter were a real bitch to get off. I ended up having to use a breaker barr for the top bolt to the starter. Hit it with lots of penetrating oil and you should be fine.

Thanks AIM, I've done starters before, believe me, I've smashed my finger enough times to learn my lesson.

I should have elaborated more. AIM is correct, don't make a gasket soley out of RTV, But IIRC, even the haynes manual also suggests putting a liberal amount of RTV at each corner of the oil pan where it dips down. I did as well.

Okay, I prolonged the life of the oil pump by using thicker oil, but now, even with the thicker oil, I am losing oil pressure once again... Yay... Meh, it was just a temporary fix I was hoping would pro-long just a little longer than a 2 months, but whatever. I'd like some opinions though. I'm losing oil pressure, but I've got no ticks, knocks, or anything else. I have a brand new oil pressure sending unit, and when the truck does have oil pressure, it's never over 40 psi. Even when it looses oil pressure, the engine runs smooth. In fact, the engine runs great all the time. So do you think I need a new oil pump?
Okay, so i need to know a few things. I am mechanically inclined, I've removed tranny pans before, done the alternators, belts, intakes, brakes, u-joints, etc. Never removed an oil pan before, never replaced an oil pump on a motor in a vehicle before. In fact, never replaced an oil pump on an engine that would ever run again.
So guys, besides the oil pump itself, and the obvious oil pan gasket, oil and filter, what else to do I need?
Anything else I should replace while I'm in there?
Do I have to remove anything to get the oil pan off?
Do I need a new oil pump screen?
Do I need new bolts for the oil pump itself or are they torque to yield?
Do I have to prime the oil pump after I have it all together?
Any o-ring seals or anything else I need for the replacement? Do I need to lube up any seals before re-installing everything?
Anyone done this before? How long does it take?

So what is your oil pressure guage reading? Middle of the guage when cold at any rpm and towards the low end of normal at a warm idle? Mine does this too so I'm interested to hear if replacing the oil pump brings the pressure to the middle of the guage at all times like it used to be.
Can't afford everything quite yet. Will probably happen later this week. When I do it, I'l let you know the results.
And thanks dhvaughan, I will do the rtv at the edges, and will do it lightly.

Cold and warm, Idle and WOT, the gauge never reads over 40. Usually around 20 at idle in gear. WOT just barely brushes 40 psi.
