Possible Briggs oil sump/pump
Wondering if someone out there could help me identify what I believe to be a briggs oil pump. Its mounted on a steel plate(like one of those that separates a lower gas tank from an oil sump; with what looks like an oil pump on it for one of the older briggs F series engines. It has a what looks like a bronze L shaped pump, soldered on at 3 points. The pump has a round "tower" like 2 inches high by probably 1/2 inch wide with a spring and solid steel pin that acts like a piston... The lower part is a square made of a filter mesh around the base; on the top of this part is a small, long cotter pin holding a b.b. in place. I'm guessing its probably for an FB or FC; any ideas? I'll try and remember to get photos when i'm at the shop. Thanks, James in Wisconsin

Re: Possible Briggs oil sump/pump
Sounds kind of like the one used in the old Jacobsen four stroke.

Re: Possible Briggs oil sump/pump
If I remember correctly the FB oil pump is a small trough with a piece of steel that stick up and and had a spring underneath and it is actuated by the cam gear. I have only had my engine apart once, this is how i recall it being. FI engines use a sort of L shaped oil pump but they are fasted to the base with screws not soddered.

Re: Possible Briggs oil sump/pump
James, got your email thanks. Yep, sure looks like an FB pump to me. If I remember correctly the FC and FE style were the same, a tall skinny trough with no pump and a long dipper on the rod. My FB had the tower broken right off on the pump and it looked the it blew a rod at one time because it broke the leading edges out of the trough. I converted it to the much better FH style system which is better for running long periods at shows and you cant tell unless you open the engine up.
