What is it? Mine's leaking and I need a new one..

[jhorse]

Got a '95 250, 7.3- Great Truck! Have a leak on what looks like a sensor located on the firewall side of the filter housing at the bottom. Part screws in and has a red wire with yellow stripe on it. Looks like it will take a 25/26 mm socket to remove it. Local parts stores don't carry much diesel stuff and had no idea what it was.

sounds like the oil pressure sending unit...

It's the Restricted Fuel Filter Sensor

I got one from the ford dealer, about $60.00.

Not sure -- you may be able to find a part number for it and see if an auto parts store has it. No one around here but the dealer could find it.

Found the part number:

Fuel Filter Restricted sensor; on filter housing 94/95; on regulator block 96/97
(Ford) E8TZ-9S283-A
(International) 1809435c1
