Goatman makes mention of using a Vacuum and Pressure guage he bought from Kragen to measure pressure: http://www.benzworld.org/forums/w140...?highlight=psi
I can't find it on their sight. Got one from Autozone a while back and it does not read up to 70 psi (only reads to 10 psi). Diagnosing a few air leaks off of central locking pump.
Anyone got a link or model they recommend for working with the two vacuum pumps?

Car burns a quart every 600 miles which apparently is the norm and has been the case since I got it at 145,000. Many tricks to these. Ask. I've learned the hard way.
