Any ideas? > =šp "gimme a nice electric fuel pump any day" Kooser Jake, AFAIK the spacer is identical as the Type 1, and my Haynes manual suggests that the pushrod should project 13mm (1/2") above the spacer (at top). To vary this, the manual suggests putting more or less gaskets under the spacer, but I guess I would rather grind the pushrod a bit instead.
