John Deere lx 279 Kawasaki 17 H.P. Fuel Pump question

I have a John Deere lx 279 with a 17 h.p. Kawasaki engine. The fuel pump is squirting gas out of the weep hole. It's still running good, but raw gas on the exhaust is not good.



I have been looking for a replacement fuel pump and they are crazy high. This mower is old and not worth a lot. Any ideas where I could find the best deal on a fuel pump. My research says it is Kawasaki Part # 99916-2164.



I appreciate any help.



Thanks
