Hi all, Just though I would pass some info on to the group. This weekend I disassembled the Fuel Flow meter on my car. I thought that maybe by cleaning it (and snooping around inside it) I could get it to work properly. Well, it still doesn't work but here's what I found: There are three fuel connections, Inlet, Outlet, and a Return line (to the tank?). Inside the housing is a (flexible?) diaphragm which divides the housing vertically in half. One side is where the fuel inlet/outlet is, on the back side is a cupped metal disk (thin sheet stock) that is held in place by the diaphragm onto housing ribs. The diaphragm appears to seal the halves from each other. There are two passages that lead to the 'electronics'(?) area where the wires come out. There are NO moving parts visible. The bottom of the 'electronics' area has what looks like a metal plug that may be removable by a special spanner wrench. I tried to remove it, but only succeeded in chipping off a piece of the housing. I gave up on it, not wanting to break it. The diaphragm was misshapen and the metal disc was loose and flopping around inside. I reshaped it and reinstalled the disc. (You could see where it had been.) There are numbers and what looks like German writing on the outside of the main housing as well as numbers on the 'electronics' area as follows: ---------------------------------- Main Housing: ^ (arrows pointing up) ^ PFEIL NACH OBEN FLECHE EN HAUT FLOSCAN 254 4011757 'Electronics Area': Chrysler logo 4222798 40110 0204 That's all folks. I may try to open that 'plug' someday. I will have to make a wrench for it. Dan Wing Imp1983@xxxxxxx '83 Imp, beige, wire wheels, factory/dealer carb conversion
