hey. something for an old carbed sube. I hope the "25" is enough...it seems to bury every other needle.
there is one discrepancy with the
link to read the guage (it seems an old school approach no big deal)
the very last one, in the right side. that very well could be modern air bypass. It is on most fuel injecteds going back even to the 1980s (My old subaru with the 1980s injected had one). It keeps vacuum from going high at idle...and appears very smooth when functioning...that is normal for that setup. If a carb, it goes way high. maybe even in stabs, until it finds a way to bypass gentle.
I may have to order one of these. Bargain.
