FITMENT NOTE -- PLEASE READ BEFORE PURCHASE
The Delphi MF0184 is a 3-LINE mechanical fuel pump (fuel inlet, fuel outlet, and a vapor return line). It is designed for Cadillac 472 / 500 engines on models equipped with factory Air Conditioning, which use the 3-line setup.
QUICK CHECK -- look at the pump currently on your engine:
• Current pump has 3 lines/ports → the MF0184 fits.
• Current pump has 2 lines/ports (no vapor return) → the MF0184 will NOT connect to your fuel lines. Do not order.
Engine swap or bare motor with no VIN? The line count on your existing pump is all you need to confirm fitment.
Unsure? Message us BEFORE purchasing with your year, make, model, engine size, and A/C status. Orders placed with vehicle details attached ship same-day with no verification delay.
