Hey,

Has anyone hook-up a Auto Meter Oil Pressure Gauge (Mechanical)to a hemi...If so can you help me with the install..a website with pictures on How to and where it hooks-up to...or a step by step walk though of it...

Thanks

 

eeeeeek. Mechanical??? I wouldn't use anything other than an electric sending unit. Much cleaner, more reliable and no mess like mechanicals if the line brakes or the fitting swells up and contracts. I wouldn't recommend any mechanical guages.

 

Mechanical is more accurate. They do not vary as the voltage changes or with a bad ground. I have never had a line leak or fail.
You need to make a T fitting to use the factory sending unit and the mechanical gauge. This will keep the PCM happy by seeing oil pressure thru the factory gauge.
