how much alky line pressure should there be?

[dboosted1]

I bought a used smc alky system with a pressure gauge on the line. How many psi should I be seeing with the button pressed and on a pump speed of 10? thanks

Not sure if this is really "apples to apples" 'cause I use the "Ford" pump, but I can peg my 100 psi gauge with DUAL nozzles at a SMC setting of 8 or above. Also not sure how many replies you'll get as I don't think too many people have inline gauges like you and me! I could be wrong, though.
