Isx 2250 fuel rail pressure

[imalumberjack]

if I am looking at this correctly the pictures are of lift pump fittings? There are three fuel pumps on that engine; an electric pump that actuates when you turn key on to start, a mechanical pump (your pics) and a high pressure pump. The fuel rail is on the high pressure side. You want do some cleaning and cure the leaks. YOU MUST check the high pressure pump for ceramic plungers!!!!!!!!!
