Q: Hello,

Is my honda engine GC190 ( 5.2 hp) will match to the General pump model tp2530J34UIL.

That being the case, I would suggest that you give the folks at General Pump a call, toll free, at (888) 474-5487 to see if that part number will match up properly with your engine, or they may be able to suggest one that will.
