Nissan Navara fuel pump relay location?

[supershifty]

Hi all, sorry to have to ask this on the AFF The Nissan forums are freaking useless.

I'm trying to help a mate out. He's got a '91 Navara D21 2.4 2wd carb. I suspect the electric fuel pump (yes, it's electric) in the tank has failed. Before I decide to pull the tank out (ugh!) I'm trying to verify the electrics are ok. We don't have a manual or wiring diagram. I know SFA about Nissans.

All the fuses check out ok, but commonsense tells me that there will be a relay somewhere between the pump and the fuse? When I turn the ignition key to the run position I don't hear any relay click, nor the pump prime.

Any ideas where the relay is located? I'm praying there is one and it's failed!

Cheers!
