I have a 1996 29 ft. scarrab w/ 502 efi. two things, I have a bad injector that is spewing gas on the motor. I want to remove all the injectors and have them cleaned and recalibrated. I have the manual and it looks pretty straight forward. any unknowns will be appreciated. secondly, I want to eliminate the vst tank. Any diagrams available to repipe the fuel system available. While I am removing the injectors I would like to replace to 24 year old pressure reg. Again any unknowns or is it plug & play. I see there are adjustable pressure regs, is this recommended. I am a back yard mechanic so any help is greatly appreciated. I have owned this boat for 20 years and just love it, so I am hopeing to make these upgrades and use it for sometime longer.

Thanks in advance
