35 PSI Boost Gauge Mounts To 6.5 Turbo Diesel

Black 7 Color 35 PSI Boost Gauge

The GMC Sierra 6.5L Diesel 35 PSI Boost Gauge was made for any turbo-charged 95-98 GMC Sierra Full Size Truck, giving you the ability to easily monitor your GMC’s turbo boost levels from 0 to 35 PSI through one gauge. Installing this Sierra boost gauge will help you guard against overboosting, which could potentially result in damage to your diesel engine. 95-98 Sierra stock levels run at about 7-12 PSI, but with a tuned diesel engine those boost pressure levels can go much higher, which is why the 35 PSI boost gauge is an optimal fit.

This adapter replaces a bolt on the intake manifold, allowing you to use the sensor to read your vehicle's boost pressure without the need for drilling or tapping.

Transmission Temp Gauge For Sierra Detroit Diesel

Black 7 Color Transmission Temperature Gauge

A GMC Sierra Trans Temp Gauge is essential for any 6.5L diesel and goes hand-in-hand with monitoring 95-98 Sierra 4L80-E transmissions, especially when these trucks are towing heavy loads. This gauge allows you to closely monitor the temperature of your transmission, ensuring that it does not overheat causing significant damage. Once you connect the included electronic transmission temperature sensor with 1/8-27 NPT male threads, this Sierra trans temp gauge will take extremely accurate readings from 80° to 260° Fahrenheit.

1500 EGT Gauge Installs To GMC Sierra

Black 7 Color 1500° F Pyrometer EGT Gauge

The 1500° F Pyrometer EGT Gauge is essential for anyone driving a 1995-1998 GMC Sierra Full Size Truck 2500HD/3500HD who is pushing for maximum output out of their 6.5L diesel engine. This GMC Sierra EGT gauge will ensure that your exhaust gas temperature is not running too hot which could result in failure, displaying readings from 0 to 1500° Fahrenheit. Installation of the included EGT Probe involves drilling and tapping the exhaust manifold to 1/8-27 NPT and then threading and tightening the Probe.

30 PSI Fuel Pressure Gauge Fits 6.5 Detroit Diesel

Black 7 Color 30 PSI Fuel Pressure Gauge

The 30 PSI Fuel Pressure Gauge for the GMC 6.5 diesel displays readings from 0 to 30 PSI. It’s the right gauge for any 95-98 Sierra Full Size Truck since they run on lower fuel pressure, with an average stock PSI range of 3 to 7 PSI. This gauge ensures your fuel pressure is running at peak levels, and that it is not too low which could result in damage to your fuel pump or injectors. A GMC Sierra fuel pressure gauge is vital to any 95-98 Sierra by helping drivers maintain their 6.5L diesel’s performance through consistent monitoring of pressure levels while driving.
