Keep fuel moving from the tank to the carburetor with the US Motor Works Mechanical Fuel Pump (USMP07800). It installs as a direct-fit replacement for the listed classic applications, including the 1959-1965 Chevrolet Impala and Biscayne, the 1963-1966 Chevrolet Corvette, and the 1965-1969 Checker Marathon.

  • Engine-driven operation: a mechanical fuel pump is actuated by the engine to draw fuel from the tank and supply the carburetor — no wiring, relay, or electrical connections required.
  • Direct-fit replacement: intended to replace a worn or failed original mechanical fuel pump on the applications listed below.
  • Signs it may need replacing: hard starting, stalling, sputtering under load, or fuel seepage can indicate the original pump is failing.

Mechanically, the pump generates the fuel flow that keeps the carburetor supplied. If a failed fuel pump is the cause of your fuel-delivery trouble, this unit replaces it; diagnose the cause first, since filters, lines, and the carburetor can produce similar symptoms.

Fitment: 1959 & 1962-1965 Chevrolet Bel Air, 1959-1965 Chevrolet Biscayne, 1959-1965 Chevrolet Impala, 1963-1966 Chevrolet Corvette, 1965-1969 Checker Marathon, 1965 Chevrolet Chevy II, 1965 Chevrolet El Camino, and 1969 Checker Deluxe. See the Buyer's Guide tab for the full list.

Is this an electric or mechanical fuel pump?

It's a mechanical fuel pump, driven by the engine rather than an electric motor, so it needs no wiring or relay to operate.

What are signs my mechanical fuel pump may need replacing?

Hard starting, stalling, sputtering under load, or fuel seepage from the pump can be signs the original is failing. Diagnose the cause first, as these symptoms have other possible causes.

Will replacing the pump fix my fuel-delivery problem?

If a failed fuel pump is the cause, this replaces it. Fuel-delivery issues can also stem from filters, lines, or the carburetor, so confirm the diagnosis before ordering.
