unhook the LDA? iirc, the whole top just pops off and there was no difference in the bottom of the pumps between na and td.. but i could be wrong.
all i was stating, was that the pumps are identical with no boost applied..
Pretty sure that's right, the NA pump has a fixed stop pin inside while the TD pump has the "moveable stop" hanging down from the LDA. This has been gone over quite a bit
.
EDIT: Not sure about how they look but IIRC the NA pump can pump just as much fuel as a TD pump, it will just smoke more until boost comes up......or you could advance the go pedal more and more as boost rises and get very little smoke.
