Fast delivery and Helpful information

1A Auto is my goto source for parts and information. The delivery of parts is fast and accurate. No going to the parts store and finding out they don't have it in stock. The information video's are outstanding. They are clear and very helpful to review before ordering to find out if the task can be done or not without special tools. They are also helpful in describing the proper order for disassembly and reassembly. That saves me a lot of time. Great job on the videos.

Eneed up seeing I had another 10 pounds of oil pressure after installing this new pressure switch. I checked my pressure with a gauge and this new switch was within a couple pounds. Very happy with it

Customer Q&A
What is the difference between a oil pressure sending unit and and oil pressure switch? Both same the same, look alike and different price. I have an actual guage reading the psi for oil so which do I need?

May differ if you have a real gauge or just an oil light on the dash

oil pressure sending unit is for when you have a gauge it gives real time psi readings from idle thru acceleration. oil pressure switch is for when you only have a light, when oil psi drops below normal operating psi the switch is tripped activating the light to come on to warn of a problem.
