Thanks for the quick replies, guys.
The gauges look identical, both are full sweep needles 0-30psi. The only difference is how they are hooked up, is that right? It sounds like the mechanical is easier to hook up and more reliable, it's also $135.00 Cheaper than it's electric(not digital) counterpart. Do I understand this right, or am I still confused??
Is the electric one the one that T's into the map sensor?
Any more help or opinions would help a lot.
Thanks
