#85516, "Hissing from fmu???"




          

OK so i got the exhaust leak before the turbo fixed, and its like a night and day difference, i hit boost sooner/faster/smoother. but as i was heading home from my long cruise, i noticed my fuel pump was making this very quiet chirping sound on top of the usual droaning whine(my back seats are still out right now so its easier to hear) im not sure if anyone elses does that or if its a problem. but then, after i turned the car off, i heard this hissing noise... so i walked around my car a bunch of times and finally came to the conclusion it was my fmu. i have the basic Vortech 12:1 fmu. anyone ever have there fmu hiss before? its not like its a vac leak because the car was off. and i guess it could be bleeding off fuel pressure, but it would just be stock fuel pressure since i wasnt seeing boost when i turned the car off. i dunno anyone have this before or have any guess as to what it could be or if its a problem? thanks a lot
