FYI.... I have been having some fuel related issues and posted several times... Rodbolt and seabob and others have been kind enough to help me out. My problem originally started out as a simple low pressure pump that was leaking gas out of the back side vacuum port. So I replaced the "leaker".The dealer had one, then a week later, got me the other 2 , and I replaced those also.,, as advised. THATS when a different fuel related problem started ... So to make a long story and alot of torturous trouble shooting hours later....Because with 3 new fuel pumps, I had to have a problem else where. RIGHT ???? Well the problem turns out to be the 3 new MALLORY brand pumps that I saved 15 bucks each on over the OEM Yamaha cost. !!!!! They each Failed and stopped pumping fuel into the VST all within a few days of each other....Driving me crazy one at a time !!!!!. The MAllory pumps were a great deal !!!!!!!!!
