Installation Notes and Tips
Verify engine and fuel system configuration before ordering, especially on 1969 Ford Bronco single action pump applications and 1971-1973 Ford E-100 Econoline models with manual steering. The 1966-1967 Ford Mustang fitment excludes high performance applications, and the 1965 Ford LTD application uses a pump without a filter can. Confirm mounting surfaces are clean and inspect fuel lines and related components before installation.
