Getting to the bottom of it!!

Right, got the front brakes finished yesterday, hard to test without the engine running. but towed her round the orchard and they stopped when jumped on.
Today i decided i couldnt wait any longer, the battery with little terminals still hasnt arrived so i hooked a standard one up with jump leads.
Everything seemed to work, lights, stereo etc. cranked her over, nothing at all. Turned ignition on, listened for the click from the relay, yeap she's clicking ok.
air filter out waft of easystart wife cranked her and she fire's!!!! yea!!!! Next, out with fuel pump, wired her direct to battery off the vehicle, nada, nothing, dead. So i guess i have found the problem. Anyone got any advice on what fuel pump to buy? where from? ebay link? Many thanks in advance you good people.

forgot to ask, are the electrical conections to the in tank pump submersed??
