Ever wonder what is inside that lil black box called the DPFE? I have and I decided to disect an old one today.

The "guts" are a circuit board encased in gel on the back side and an area that measures gas pressures on the hose side.

Just in case you ever wondered ....

I took my old 1 apart also. Don't have pics, but yeah it's not much to look at.
 












yeah.. about how nasty My DPFE was... haha
i dont have pictures either, but the two inlets for the hoses had corrosion on them, and had they had begun to break apart inside of the hoses.. im glad i replaced that thing..
btw.. i had the metal one, i think it was original too.. replaced at 191,000 miles :)
 






I had the metal one also, & it was all corroded, & had all this white gunk in it. Mine smelled too.
