For anyone who replaced their fuel pump... I would like your insight as to how you replaced the unit back into the tank. I thought I had it seated correctly, second time filling it up gas is shooting out the top. I did not use the crazy tool, and assume no else has either so what was the trick in making sure the gasket is seated? How many turns of dumb metal thing was tight enough? It does not appear at all to be threaded. Seems like a quarter to half turn would seal it then any more would unseat it. TIA.
