Need help installing aftermarket gauges on my 1971 Pontiac LeMans Sport

[Btc89]

I bought some summit racing aftermarket gauges. A water temp, oil pressure and volt gauge and I need help hooking them up on my pontiac. I have a 1971 Pontiac LeMans Sport with a Big Block 350. If you need more info let me know. If anybody could help me that would be great. Here is the link to the gauge i bought. http://www.summitracing.com/parts/sum-g2973-v/overview/

I need help getting power to all the gauges and how to hook up the oil pressure gauge and the amp gauge. I think I can hookup the water gauge but I don't understand the directions that summit gave me. I have some fittings and a nylon tube and I have no clue where it goes.

The nylon tube is for your oil pressure and has to be routed where the oil pressure sender is above the oil filter. You have to buy a T adaptor so you can use both the sender and your gauge. You need power from any circuit in the fuse box that is life when the engine is running. For the ammeter you would use diagram C

Okay. How does the oil pressure gauge hook up with the nylon tube on the back of the gauge?

There is very clear diagram in step 7 section A. What part of that do you need help with?

I got the oil pressure nylon tube hooked up now I don't know where to hook the other end up at.

Did you read post #4 above? You do know where the oil filter is and can see the oil sender above it? The picture below shows the large sender used with a factory pressure gauge.

Yeah I see the oil sender. What do I do from there?

 

[melsg5]

If you want the factory light to work you remove the sender. Take the sender and the last fitting on the nylon line and take them to an autoparts store and ask for a "T" adaptor. You screw the adaptor back into the oil filter mount and screw the sender into one hole of the fitting and the fitting for the nylon line into the other hole.
