Interesting thoughts.

I also feel that residual rubber particles remaining in the pump body from the deterioated o-rings is a contributing factor. You can have everything sparkling clean before removal and rinse the valve holder numerous times before reinstalling but will still have contaminated fuel that remains inside the lower portion of the valve.

When restarted those particles end up at the inj.

Iin an attempt to avoid this I've suggested more recently that once the DV's are back together a few ounces of fuel be pumped out before the hard lines are reconnected to the inj's.
