I'm with you. I'm about to replace a pump in our 92 sedan, but did not recall all the details. However I just pulled two out of a junkyard, so I can give you the benefit of my re-learning. Both the hoses at the top of the unit are clamped in place and both can be removed by removing the clamps and then pushing the hoses off. I actually used the spoon-shaped handle for the lug wrench. This provided a smooth edge that didn't damage the hoses (though being in a yard, I wasn't that concerned really). I do not have a bung nut wrench to remove the retainer on the pumps. Instead I use an adjustable straight pipe wrench. It's fine to actually bang on the retainer of an empty tank in a junkyard, but I would not advise it on your tank with gas in it. The wrench can be fitted to the retainer tabs and turned with an adjustable wrench on its handle. By far the toughest part is getting the unit out of the tank, especially on sedans, where the top of the tank is further down below floor level. I found it possible to press the pump body tighter to the sender unit to help get the pump past the tank opening. The pickup "sock" extends at a right angle to the inlet though. It's rather long. It takes some twisting and patience to get past the pump, sender float and the pickup sock, but patience will out. Going back in will certainly be just as difficult.

Pump to filter hose, is that the other hose you asked about? Yes, you can do this without disconnecting the others, but you will have spillage. You can clamp the hose from the tank, but do not clamp the one going forward. It's hard plastic and can be broken. Not that much fuel will be lost coming from the front of the car, a can will catch it handily. However the flow from the back of the car...well that can be quite a bit if you don't block the line.

Good luck!
