C5 oil pressure sender quality
Is there a higher quality oil pressure sender than stock? I am taking the intake manifold off and am going to replace the sender while it is off.
And, What about the vacuum line. Is that old and should be replaced. Is that a part or just some rubber line?
What else should I do when the intake is off. I'll need new gaskets...........are some better?

I did this just the other day. There's no need to replace the line because it's old. What you want to do is lengthen it and you'll see why as you're removing the manifold. After you get the manifold off, pull the plastic line out of the elbow on the back of the intake. On the 'car' end, I cut mine about 4" above the wiring harness. I then inserted a short length of said plastic line into the elbow on the intake (long enough to make it bottom out in the elbow). I then bought some 5/32" line, cut it to about 6," slid one end onto the existing tube (car end again) and the other end to the elbow with piece of tubing sticking out.. I put a ty-wrap on both ends of the rubber hose, which was probably unnecessary as this is a vacuum line and not a pressure line. The beauty part of doing it this way is there is no stress on the original tube that goes into the harness and there are no tight bends. The excess hose winds up hidden behind the manifold.
If you have the rubber hose in hand you can do this whole job in 5 minutes.O'Reilly's stocks the vacuum tubing.
Regardless of anything else you read about doing this job, the hose you need is 5/32" (at least it was on my car.)

Ive had my car for 19 years. Had 3 or 4 OEM senders fail. I'm thinking GM sources the senders from the same company that machines LS7 heads!! I went aftermarket from O'Reilly, haven't had an issue since. Been so long, I can't remember the brand they sell. I do remember they had an El cheapo version, and a lifetime warrantied one. I got the El cheapo. 35,000 miles, at least 5 or 6 years, still good......

IMO, spend a little extra and relocate the oil pressure sender. Then pick up a replacement sender from an auto parts store that offers lifetime warranty, and just replace the sender as often as needed. Should only take a few minutes to replace a relocated sender.
