It is a carbureted engine. I still don't want to use oil pressure (at all)
as the means of detecting engine operation. Beyond that is the need, as
Nate pointed out, for running the pump initially to refill the carb after
sitting for a month or two.

My recolection was that when they were first used, the socket for these
relays in some cars was an add-on - not integral with the fuse box. My
trips to the wrecking yard so far have been futile - virtually all of the
relays are being stripped out of these cars (& sold on ebay?). I suspect
that they may be leaving the wrecking yard in jacket pockets.
I do now have a fuel pump relay Socket out of a Volvo, but no relay. From
what I've seen, there are a number of different relays that Volvo used - I
suspect that the later ones do not have the start timer built in. Anybody
know which Volvo relay(s) do have the start timer & ignition sense built in?
