back under floorboard a bit. its there.
neighbors with a GC1723 AND a GC1725M (same setup) not home so couldn't grab pics. I did run down and try though.
since I was not able to get pics then do this. follow your fuel hose from injector pump back towards fuel tank.
you WILL find that filter assy.
trust me, its there. changed both recently. 1723 was 3 weeks ago.
unless you have specific spanner wrench a rag and large slip joint pliers are your best friend.
bleedingwise....meh. if its been running anytime within past 6 hours loosen the screw, watch the bowl fill, tighten the screw and start and run.
handled this many many (did I mention many) times on gc2400, gc1710, gc1723, gc1725 and MF1532.
