leaky fuel pump

[Chillitt]

pulled the injector pump off ferrets truck today(deep joy.. not cold at all.. ) here is a picture of the underside, should there be a bolt in the threaded hole? is this why it leaks? or are we clutching at straws? also if its not that, the is an oval plate on the back of the pump, if we pull that to replace the seal, will any expensive springy bits leap out, never to be seen again? ta.

That threaded hole looks a bit too clean like something was in there recently!
Have a look here for reference...http://www.toyotasurf.asn.au/techsite/fuelpump.htm

My repair manual doesn't give an illustration of the underside, and I aint going outside to have a look at mine in this tornado we're having at the moment!!

I have an old pump body here and just had a look. There are three holes the same size. Two toward other end of pump and all look to have had a plug or something in there at sometime. Close inspection reveals they are blind holes so nothing can leak from them. Probably mounting points for body during machining or maybe for bolting pump to something during transport.
