I have a 632,, year unknown,, Ford industrial 2 27 4E engine. I lost oil pressure and managed to stop before ruining the engine. I am getting the crank ground, doing a valve job and new rings. The cylinders are in excellent shape. I am trying to find a new oil pump for this engine. Bobcat online does not show a oil pump,, gives an old part number that doesn't work. This is a external oil pump. Has anyone utilized a oil pump from a pinto, fiesta or other ford 1.6 liter engine. I have found a pump on line,, if it's right but it is $170 plus shipping which seems steep. Thanks
