Dodge Repair Questions? Ask a Mechanic for Answers ASAP
Hi there. Thank you for posting your question.
Fuse 39 (20A) feeds the power side of the relay that supplies power to the in-tank fuel pump. PTC 1 (7.5A) feeds the control side of that same relay (see attached graphic for fuse location). Ground to the relay is provided by the PCM.
Let me know if you have any other questions.
