Looks like the pn#15029 seal kit is long gone. I can find the injector upper and lower o-rings, but can't track down the four o-rings for the two metal tubes or the other two o-rings for the hose fitting on the top of the fuel rail. Does anyone have a source or size? This is on a 99 150hp 2.5l.

Ensure any O-rings used are fuel-resistant (Viton/FKM or nitrile, not standard rubber) to withstand marine fuel and ethanol blen
