What’s the part number for the quick disconnect?
I removed the medium filter with needle nose plier s and mangled the black piece you push against. Thanks in advance

I replaced 10 micron, main fuel filter and vst filter —- should I replace this one and the “mystery” filters or just see how it runs. It had not been run in 4 years but ran great up to being stored.

  This filter should be replaced every 100hrs according to Yamaha’s recommendation. If you changed the VST filter, change this one too.
