Ossablt Posted June 29, 2013 Share Posted June 29, 2013 Picked up a B30 with a EN331, missing some parts. Wondering if some one could send me some pictures of the engine, fuel pump, air compressor and brackets, air cleaner. Anyone know where I might find these parts?

Maddog13407 Posted June 29, 2013 Share Posted June 29, 2013 most B30's had juice brakes so they didn't have an air compressor and 99% of everyone I have seen had a small oil bath air cleaner on top of the carb similar to an old Ford truck. I have seen a few with air compressors but they were belt driven and mounted to the top of the head as the 331 didn't have an opening in the backside of the timin case like the 401's did. they also didn't have the external air cleaner and the tube thru the firewall like most B models did. I have seen someone put a 401 in a B20 with juice brake. they simly took the air compressor off, removed the drive pulley and replaced the air compressor so the oil would run thru it.

Ossablt Posted June 30, 2013 Author Share Posted June 30, 2013 This one does have air brakes, but compressor and brackets are gone. Generator is also missing. Where does the fuel pump mount on the 331?

Maddog13407 Posted June 30, 2013 Share Posted June 30, 2013 should mount right to the side of the block, its a generic lever driven AC pump driven off the camshaft. here is a picture with the belt driven air compressor and the bracket that bolts across the head. also shows what the air cleaner should be like.

Ossablt Posted July 1, 2013 Author Share Posted July 1, 2013 I can't see any place that the fuel pump was mounted on the block. There is a block off plate, but it appears to have been on there a while. Not sure if that is where the fuel pump would have been.

Maddog13407 Posted July 1, 2013 Share Posted July 1, 2013 that block off plate is where the original fuel pump would have been mounted to with the sediment bowl. I assume someone probably added an electric fuel pump on it and took off the cam driven one. the original fuel line would have ran up the left hand side of the frame, to the fuel pump, then stuck up beind the water pump, curved around and bolted to the right side of the head under one of those 3/8's bolts then curved into the carb. the one in the pic I showed is cobbed and not original.
