I'm not trying to make a point about the MAS itself, just pointing out that it contains the fuel pump relay in some models.

I see yours is a 93 300E. Out of curiosity, I looked up your model at this site parts data base and saw that neither the 2.8l or 3.2l 93 300E have a MAS. I'm assuming this is not an over-sight. If it's not, that's good for you because you must then have an independent fuel pump relay which costs WAY less than a MAS unit.

I didn't read everything prior to this. Has your fuel pump relay been replaced?
