The fuel pump is located in the top of the fuel tank. It is accessed by removing the floor of the trunk, a couple of plywood boards covered with thin carpet. There is a large disc which covers the fuel pump, with a rubber gasket/grommet surrounding it. This is easily removed with the blade of a screwdriver or other simple lever. Disconnect the battery. Remove the wires from the pump and the fuel line fitting on top of the pump. There is a large hose clamp that secures the pump to the tank, which is removed with a 7mm socket. I prefer a deep-well socket with a universal joint and an extension to the ratchet wrench. Once the clamp is loose, you should be able to lift the pump out of the hole. The pump is in a bucket with a screen/filter on the bottom. There are actually two pumps: a small low-pressure feed pump that keeps the bucket full, and the larger Bosch fuel pump that feeds fuel to the engine. The smaller pump is the more likely one to fail. It is also far less expensive than the main pump. When you replace the pump assembly, make sure the wire to the feed pump are plugged in to the connector in the side of the fuel tank.

Where exactly is the fuel pump access panel located on a 1996 Saab 900 SE turbo?

If it has one it will be located directly above the center of the fuel tank. It may very well not have one, which in that case you will have to remove the fuel tank to replace the pump.


Will a 1987 Saab 900 motor fit a 1993 Saab 900?

Yes... sort of. Which engine are you trying to replace? Which engine do you have from a 1987? Turbo or non-turbo? In 1987 there were two non-turbo engines, both 2.0-liters, an 8-valve and a 16-valve. The fuel systems for those two engines are different. The non-turbo engine in a 1993 900 was 2.1-liters and had yet another fuel system variation. It could be done, but you would have to replace the entire fuel system and probably the ignition system to make it work correctly, and you would have a less powerful engine than was available in 1993.

Trouble with your 1984 Mercedes 300SD Turbo diesel engine choking on uphill stretch?

If it runs fine on the level but loses power on the hills, check the small fuel filter and if it is OK replace the big fuel filter. Do it yourself for about $10. A dirty filter keeps it from passing enough fuel for a hard pull.
