There is a giant thread here on relocating the sender with an extension. I run one on my daily 99 and just ordered another for my newer Z. If the sender ever goes again, you can replace it in less than 5 minutes. Search my handle and oil relocate and the thread will come up. Cost is about 100

Is it really that easy? If so, I'd probably just do that. Assuming you leave the throttle body, injector rails, etc. all attached and just lift off the manifold. Do you replace gaskets each time you remove the manifold?

Unless you are pro or have done it several times before it will take a lot longer than 30 minutes to do the job. You will need to remove all the air cleaner and mass air flow sensor and all other assorted electrical connections and tubes. Most people remove the throttle body for better access but it is only 3 or four bolts. The fuel rail can stay attached and you can usually reuse the same gaskets several times if they are in good shape. Don't forget to extend the vacuum line at the back of the manifold to make installation easier. I'm sure there are u-tube videos of this if you do a quick search. I suggest you take the time to view some of them.

Here's a good write up with pictures. It should be very helpful if you have never done this job.

A small coolant line runs thru the throttle body. The line is not needed unless you drive in really cold weather. Many people simply by pass it by connecting the ends or just plug the ends up with a screw while you work. If there is no pressure in the coolant system only a small amount will drain out even if you don't do anything but it can make a mess.

Years ago I relocated my OPS to the left cylinder bank and added a OP gauge before the sender. A friend told me to find a repro yard and by the OPS from a low milage C5 if the opportunity was available. I was able to do that and put it in a safe place. When my original finally when nuts, I could not find it so bought a bronze on at AutozZone. Eventually found the good one that I hid on myself and this week, the AZ one first showed low OP and then went to 80+. Dropped the OEM one back in and it shows about 2 lbs higher pressure than the aftermarket. Now I am back looking for another low mileage HM OPS. The relocation made it a dream, unscrew old,put in new and 3 minutes later your done.
