AnswerWhat do you mean by haywire? Without more information, all I can tell you to do right now is to replace the filter you are using with an AC/Delco filter. The oil pressure sending unit may be defective if you are getting erratic readings.

I mean that the water temp gauge needle goes way past the point to where it bottoms out and so does the battery volt gauge needle and the oil pressure gauge needle and the tach needle works when it wants to.

How do you i test the oil pressure gauge on a 1998 Chevy?

Take the wire loose from the oil sending unit and then turn the key on and ground the wire to the engine somewhere and the gauge in the truck should go all the way past the highest point. If it don't then the gauge in the dash is bad are the wire going to it ( The 1 you grounded ) is broken. If the gauge is reading low oil pressure, Then unscreew the oil sending unit on the engine just behind the distributor, were you took the wire loose from. Then install a OIL PRESSURE GAUGE into it's place. Then start the engine and read the pressure, Now compare the reading on the dash gauge to what you are reading on the oil gauge.


What should you do if you have an above-ground pool with a sand filter and the pressure gauge is only reading at 5 but you changed the sand in the filter and it still won't raise the pressure?

You may need a new pressure gauge. They are inexpensive and can be found at any place that sells pool products. OR That may be all that you are going to get out of the system you have.

Why after backwashing your pool does the gauge not go back down?

Your gauge could very well be bad, many pools that we took care of the gauge on the filter was bad, after backwashing the filter just check any of you lines going back to the pool and your should notice the pressure is a lot higher. A lot of people just check the flow by placing there hand at an outlet to check pressure than by walking over too the filter and reading the pressure, instead of buying a new pressure gauge.


The toilet's water pressure keeps going up and down with each flush...why?

This depends how you are perceiving this "pressure going up and down" . I've repaired and replaced toilets for years and couldn't imagine how I'd gauge pressure doing this. Maybe you are mistaking pressure for flow rate and something is plugged up somewhere in your toilet.
