Take a small hand held mirror and a flashlight and take a look. Shine the light at the mirror at the proper angle and you'll be able to light up under the deck. That's what I did checking the sending unit wire on my 18 and found the pick up and fuel line at the rear of the tank, filler at the front where the inspection plate was. If you measure back to where the fuel line comes out of the tank, you could cut for and install a new inspection plate. Then all you have to do is fish the new line in.
