hey guys Im gettting a Boost leak from my MAF sensor, it is actually coming out from the sides, I was wondering if anyone has ever made a gasket for it, or it there is something Im missing. I have both screws in it but it still leaks

There should be a small piece of rubber that sits between the sensor and the housing. W/ a decent used seal in there i have seem them start to leak a very minor amount by about 20psi (when pressure testing a system). Hope that helps.

Then you pressurize the system up to a cpl PSI above your peak boost and listen...a little soapy water can come in handy here.

Cool, just making sure you know thats were it's coming from, because I have a boost leak and I'm having a hard time finding it.I think it's my Bov but not sure I was go to try a fogger to find it just haven't had the time. Has anyone used a fogger on here to find a leak?

sorry i can't help w/ the part number, or even if it can be purchased separately. I have heard that the 05-08 Mustang uses a very similar MAF sensor, maybe ford sells the gasket only, and could work?? I haven't tried to swap one or even looked at one in person, i just remember another tech commenting on it, so pursue that idea at your own risk!
