Symptoms
Hard hot starts, stumbling or dying under load. Several Bring a Trailer sellers list a replaced fuel pump and filter in recent work on 2.6 Raiders and Monteros.
The fix, step by step
- Start by replacing the fuel filter and any perished rubber fuel hose, then check fuel delivery.
- If the original pump is weak, replace it with the correct part.
- TimmyTheGreaseMonkey has a video on converting a Dodge Raider or first-generation Montero to an electric fuel pump, and another on his 'must-have upgrades' for these trucks.
