ok so the shop that installed mine, what do I replace it with? I have an advanced auto and a pep boys near by. please email or private/instant message me if possible.

yeah I knwo Im retarded for asking, but money is light and I dont wanna buy the wrong stuff

Here is how I installed my boost gauge.

The other pictures posted below is my setup for the Vacuum lines. I replaced the EGR hard plastic line with a rubber vacuum hose. I also attached the nylon line for the boost gauge using a brass union instead of HRC's way of compressing the brass compression fitting and then sticking the nylon tube into a rubber hose (the compressed fitting is supposed to keep the nylon tube from coming out of the vacuum hose under boost). HRC's design didn't seem to be very well thought out and the brass union definitely is more reliable - won't allow a boost spike. My design works nicely since the boost guage already comes with a compression fitting on one side and NPT threads on the other. Here's a quick diagram (sizes are approximate, I don't remember the exact sizes I used):


1/4" Hose Barb to 1/4" Male NPT --> 1/4" Female NPT Union --> 1/4" Male Compression Fitting (supplied with Autometer Boost Gauge)
