You all are close to the problem, but it's so obvious that it often is  
forgotten. After 20 years of use, the diaphragm in the fuel pump has quit  working. 
The parts can be had from your dealer. The kit comes with everything  you 
need to replace it: new diaphragm and gasket. All together it's a fifteen  minute 
job.

Michael  T,

You may wish to check out the Yamaha parts website  at:;
http://www.yamaha-motor.com/outboard/parts/home.aspx

Put in the  following:
Step 1: Product Line = Outboard
Step 2: Year = (your motor's year)
Step 3: Model = (your  motor's model or select one of the 8hp)

I tried a 1988 8hp long shaft  as a guess and found the attached image of the 
gas tank & filter (#22)  (it is probably at the very bottom of the email)
