Marty T | Tractor fuel pump problem fixed with a 5¢ o-ring.. David Brown 990 @MartyT | Uploaded August 2020 | Updated October 2024, 16 hours ago.
The previous owner of the DB990 sold it because he was having trouble with air getting in to the fuel pump. I've solved the problem with a new o-ring on the hand pump intake fitting.
