            I have the amber engine code and I erase it with the insite and it comes out when I'm loaded up a hill I change the sensor filters and still doing it in the rises I have a leak through the connections of the pump could this be the problem

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!!!!!!!!!
