JACK UP REAR OF CAR AND SUPPORT WITH JACK STANDS. STANDS SHOULD BE PLACED UNDER REAR DOORS AT FOLDED SHEET METAL, AKA ROCKER PANEL. MAKE SURE TO GIVE ENOUGH ROOM FOR REMOVAL OF TANK WITH FUEL TANK ON JACK. REMOVE THE HOSE CONNECTING TANK TO FILLER CAP TUBE. SIPHON OUT ALL THE FUEL YOU CAN. NEXT, SUPPORT TANK IN MIDDLE USING A PIECE OF PLYWOOD OR OTHER THIN MATERIAL TO DISTRIBUTE WEIGHT OVER A GREATER AREA OF TANK TO KEEP JACK FROM BENDING IT TOO BAD.RAISE JACK AND APPLY GENTLE PRESSURE ON TANK. 2 METAL STRAPS HOLD TANK IN PLACE. EACH HAS A NUT ON ONE END. RENOVE NUT, SLIGHTLY LOWER TANK WITH STRAPS BENT OUT OF WAY. NOW DISCONNECT ELECTRICAL PLUG FOR FUEL SENDING UNIT, USUALLY GREEN WITH A FEW WIRES.DISCONNECT ANY OTHER HOSES, PRESSURE HOSE AND RETURN HOSE AND VENT HOSE. PRESSURE HOSE AND RETURN HOSE MAY TAKE A SPECIAL TOOL. YOU CAN CHECK AHEAD OF TIME AT PART STORE. CAREFULLY LOWER TANK. WHERE LINES CAME FROM TANK THERE IS A ROUND FLANGE THAT HAS PLACES FOR A FLATHEAD SCREWDRIVER TO PUSH AGAINST TO ROTATE. USUALLY 4 STICKING UP. YOU WILL ALSO SEE THE FLANGE HAS RAMP LIKE PLACES GOING UNDER TABS ON TANK, THESE ALLOW THE FLANGE TO SORT OF SCREW INTO TANK AND SQUISH SEAL TO KEEP GAS FROM LEAKING OUT. ROTATE FLANGE COUNTER CLOCKWISE BT HAMMERING ON SCREWDRIVER AGAINST ONE OF THE 4 TABS OF THE FLANGE, GO AS FAR AS YOU CAN AND MOVE TO THE NEXT TAB IF IT GETS DIFFICULT TO ROTATE.REMOVE WHOLE SENDING UNIT WITH SEAL. DEPENDING ON WHAT YOU WERE SOLD AT PARTS HOUSE CHANGE OUT PARTS AND SEAL AND REINSTALL, SOUNDS HARDER THAN IT IS . WHEN YOU THINK ABOUT IT, IT'S ONLY 2 NUTS AND A COUPLE OF HOSES.

Newbie here! How to install fuel pump on 96 olds regency elite?

You might benefit from the 96 Regency Elite factory service manual purportedly available by a download for $22, if scrolling through pages or using CTRL F to hunt through a PDF is something you are comfortable with. I have no idea if it tells you to check for rust in the fuel tank. https://www.tradebit.com/filedetail.php/281883502-1996-oldsmobile-regency-service-and-repair-manual

The Haynes group is of course more familiar and there seems an aside mention of the 96 being covered in spite of the title. https://haynes.com/en-us/oldsmobile/regency/1997-1998

Regarding videos, I encounter such for the Olds Bravada and the Olds Aurora, both 96 models: https://www.youtube.com/watch?v=dO3QkeMTwP0

I have 1998 old regency starts up when engine cold but after engine get hot it wont start back up untill cooled off & shows low fuel pressure coming from fuel pump?

Your fuel pump is not supplying the correct fuel pressure, this could be due to a worn pump or a faulty fuel pressure regulator, Unfortunately due to the high pressures in these systems you will need to get someone with the correct testing equipment to test for you. When it is hot the low pressure means there is air in the fuel lines which evaporates in the lines when hot which is why it is not starting when hot.

My 1998 oldsmobile regency only goes 105 mph

is that a problem? I believe that is the top speed until the ecm cuts fuel to the engine. mainly because of the speed rating of the tires.
