My boost gage problem
 

I just got my boost gage from Summit, It doesn't read at zero. Is this going to be problem, like I think its going to be? I emailed Summit, but I have not received a reply. That was about 2 weeks ago. What should I do?

no sure but on mine there is an index screw in the back .to set it to 0.

also call the tech line or autometer directly i had a problem with my fuel gauge and autometer sent the proper adjusting screw out for me.

I didn't count on it being adjustable. As you can see in the pic, I never opened it, I guess its time!

I have had bad luck with Autometer Boost gauges myself. The one I have now after 4 replacements still reads 2 psi off. When it shows 6 psi I am at 8 psi. When I am at 10 psi it shows backwards it shows 8 psi. I give up with the silly thing. I keep it to show the vacuum because it seems to be always correct. I run a PMS unit and I have a remote mechanics 5" pressure gauge and they show the same psi but the Autometer is always off.

yeah i think i had to turn the housing to zero it if i remember right it was a long time ago it was the fuel pressyre gauge that had a zeroing screw

Well I finally opened it. It is not adjustable in any way that I can tell. I never did hear back from Sumit. I guess I will pay the shipping and sent it to Autometer for warrenty.

You might try hooking up some pressure to it or a vacuum pump. It might actually read right, but the zero might be off. Before I would send it off, make sure that it truly is off.

is there a light bulb plug in the back?
 

i had the same gauge and i put my finger in the back and pushed on the spring inside. it moves the needles rest point......

Just an idea before it goes back!

Wow someone had some time on there hands to look through the arcives!

Thanks I will try it.

There is a big cap screw on top you loosen to zero it. I had to do it on mine. It was obviously sealed up on a day with lower air pressure than the day you took that picture :) Check your weatherstation and try to zero it on a day with "average" barometric pressure in your area.
