Re: Oil Pressure Gauge Problems
First, why did you put a gauge on it? Was it for looks or did it make you suspect low pressure because of strange un explained noises? Knowing how some gauges are, it's pretty hard to find one that...

Tell me more of what parts combination you have.

I think your setting your self up for an oiling problem.
Here is why I feel this way. On the U model engines that get a better than oem pump is a good thing. Your aftermarket pump may...
