Retz Posted October 27, 2015 Report Posted October 27, 2015 Hey guys. I found a leak the other day from my mechanical fuel pump on my M20K 252 (Continental TSIO360MB1B). It appears to be either coming from the outer gasket on the back side of the pump, or from the plug. See illustration. I can't find a part # for that gasket in the continental parts books. Any ideas? Part #s? Experience?
MB65E Posted October 27, 2015 Report Posted October 27, 2015 Might try a few accessory shops that overhaul the pumps. I'd be Leary of pulling the pump apart to change seals unless they were external. -Matt
Guest Posted October 27, 2015 Report Posted October 27, 2015 Its time to send the pump in for repair. The leak is coming from the un metered fuel pressure regulator. The bolt you're pointing to is the adjustment screw. Clarence
wpbarnar Posted October 27, 2015 Report Posted October 27, 2015 I experienced problems earlier this year with a similar pump installed in an M 20K with a TSIO360SB2N. If it is a case where the pump needs internal hard parts ( more than just seals ) you may end up dealing with T C M. Mine needed the metering rod which controls the mixture. Ended up having to purchase an overhauled pump from T C M as they would not sell that part to the overhaul shop. Cost me extra time shipping the pump around and waiting on the first shop. If time is important to you, you may want to ship the pump to TCM in Mobile Ala Their service was good but it came with a price. Bill
