Hi Ken,
 
  
 
The write-up linked from this page: https://c320.org/filemgmt/viewcat.php?cid=5
 
Direct link: https://c320.org/filemgmt/visit.php?lid=192
 
  
 
The Yanmar part number for the replacement pump is 129301-52020. You also need a new gasket (Yanmar 121520-01851).
 
  
 
You an get after-market parts for about $40 and Yanmar OEM parts for about $120. Given that the pump has been working fine for almost 30 years and I don’t intend to replace it again, I bought the OEM part.
 
  
 
I also replaced the bolts that attach the fuel lines (Yanmar 105582-59150). That’s definitely not normally necessary, but in my case, I discovered that the cause of an ongoing tiny fuel leak was where one of the bolts had been overtightened and damaged the threads so replacing both for $10 seemed worth it while I was doing this project. Either way, you should replace the 8mm copper washers (2 on each side).
 
  
 
Hope that helps,
 
  
 
Ade.

Hi, what replacement pump did you use and can you post a link to Troy's write up.

I just wanted to send a quick note of thanks to Troy Dunn for writing up and posting the instructions for replacing the lift pump on the Yanmar 3GM30F. I replaced mine yesterday. It turned out to be a straightforward procedure, but I was glad to have reviewed Troy's write-up ahead of time. Removing the remains of the old gasket was time consuming but otherwise the replacement was quick and easy.
 
  
 
Thanks again,
 
  
 
Ade.
