the lift pump is inside the fuel tank

its accessed by removing the back seat cushion and removing the access panel in the bulkhead

this will reveal the fuel pump module which includes the level sensor

Customer: replied 1 year ago.
I have cleaned the tank and found no pump now l would like to know if the high pressure pump is coded and the low pressure one
Customer: replied 1 year ago.
I just want to know if the high pressure injector pump and the low pressure one are coded and nead computer to set up
Expert:  Matt replied 1 year ago.


Ok only the injectors are coded so you can swap the pump with impunity

however on some versions of the pump the (rotary type) then you need the diagnostic tool to set the timing up , so no coding is required just some specialist tools to set it up
