For peace of mind, rent (free) a fuel pressure test kit from your local auto supply store. It will (should) include a selection of threaded adapters to suit various applications; you want the M10x1. Install in place of the stock sender, start the motor and read the gauge. Remember that you also have a red low oil pressure warning light by your fuel gauge that would be lit if you were in trouble. Changing the sender is not easy as there is little room for wrench swing and the clearance on the bottom is usually too tight for a stubby 14mm wrench. The tool I made from 3/8" rod stock and a donor 14mm wrench though makes it easy. It's 15" tall with a 6" handle with about 7/8" between the wrench throat and the shaft.









If you have a set of 3/4" drive 12pt sockets, use the 1 - 11/16, a short piece of 3/16" or M6 fastener (cut the head off a bolt) and some grease. Use the grease to stick the rod in the sender body's slot, drop the socket over and turn to remove. If, when you put it all back together, you do not have a new copper washer, just put some sealant such as Permatex #2 on both sides; it will help keep the washer in place while you fish around for the hole.
