Hi guys,

I am wondering about buying a fuel pressure gauge. It looks like there are 2 types of electrical gauges: 15 psi and 100 psi. Which one do I need?

Secondly, It looks like the electrical gauge is about $180. but the mechanical is only around $40. Is there a significant difference in the amount of labor required to install the mechanical one? I will not be doing the work myself so labor costs are important.

Any thoughts on this issue are welcomed. I am sure it has been covered before but I have read through a number of threads and still have these questions.
