With this Temp gauge, i have a big block Mopar, can i run the temp tube under the intake manifold on top of the lifter valley pan. Will it pick up extra heat and make the gauge read higher than it really is? Or should i run it on top of the intake between

Asked by: Grumpy468
Thank you for reaching out to us. The 2399 temperature gauge features a copper tubing with a metal coiling around it. While it designed to handle engine compartment temperatures, it would always be recommended to be routed away from and not directly touching engine components.

can I get the water temp gauge in electrical in lieu of mechanical

Asked by: JimG
Hi Jim, thank you for the question. In the AutoGage series we offer only mechanical gauges, except in our mini console model 2391. Throughout the AutoMeter line we offer several 2-5/8" electric water temp gauges. However, nothing sold in a 3 gauge set. We sell the panels separately and you would have to purchase each gauge individually in the AutoMeter line.

Could I get this exact unit with orange needles? 

Asked by: Drewsky67
Thank you for your question. Unfortunately, these gauges cannot be customized so they are not available with orange needles.

I purchased a auto gauge # 2399. In the kit there are three rubber grommets. My question is how does the large solid grommet for the temp gauge go around the temp tubing & in the firewall when the grommet is solid?

Asked by: keta
Hi Keta, thank you for the question. The larger rubber grommet must be split or cut and then you can open it up to go around the mechanical temperature tubing.

On the 2399 gauge set will a Allstar Performance part # ALL 46110-36, braided steel line work on the oil pressure gauge. Does it connect right to the gauge or do I have to buy any fittings or adapters? If so, can you provide part numbers.

Asked by: keta
Hello Mike, thank you for your question. 2399 oil pressure gauge has a 1/8" NPT connector. If your braided steel line connects to a 1/8" fitting, yes you can use it. It looks like the line you mention will connect, however, you should double check to be sure.

Do either the 2-5/8" or 2-1/16" gauges come in a 4 or 5 gauge under dash console?

Asked by: Guitarman 387
Thank you for the question. There are no 4 or 5 gauge panels for simple under dash mount. Only single, dual, and triple. We do offer 2 x dual panels separately which you can add gauges to if you'd like to run 4. The 2 gauge panels are 2237 (2-1/16") or 3232 (2-5/8").

2-5/8" is the hole size, correct? What is the diameter of the outside (chrome bezel) of the 2399 gauges?
