will a oil guage work the same as a water guage for pressure?
Hit up Grainger in Phx on washingot by Kachina. I bought one and it was liquid filled and stainless steel. I got it under my work account and paid pennis on the dollar for it. If you need a discount call me. I can will call one on a cash ticket and all you gotta do is pay and pick up/Let meknow brotha
