This being the correct forum to ask questions in...thanks to a detailed explanation by Graham....thank you...I have several issues with our 04 XJ8I have to replace the fuel pump for starters and can find zero videos or instructions as to how it's done. Let's just start with this problem and thanks again for your helping comments in the past. I apologize for not understanding computer forums that well but take my age of 73 and hold it as my shield 🛡️
