[QUOTE="scuba623, post: 18489, member: 1898"] Ok, an update. First thing is i found out that it is really a 453. I dont know if that makes a difference or not but the stickers were mostly gone and when i studied it for awhile i found that it is a 453 not a 463. Anyway, what i did today was check fuel pressure. What i found is i get very little fuel after the fuel transfer pump through the hose that connectors to the fuel injector pump.(these terms might be wrong so please correct me if they are). I disconnected the lines and cranked the engine over to check pressure. I would get better pressure by squeezing the fuel bulb than by cranking it over. I would also get very little pressure through the injector lines when i cranked it over. Some questions i would have are; what are the fuel pressure specs on a machine like this? And how much fuel should come out of the injection lines while im cranking it over? Lastly, is there an additive that i can add to the fuel to clean all the lines and injector pump? I am wondering if the plungers are getting sticky or stuck or something from sitting too long or is the best fix to just get a new pumps.Any ideas? Thanks for your time. [/QUOTE]
