AUTOKAY 6V Universal Inline Electric Fuel Pump for Carbureted Engines — 5–8 PSI, 5/16" Fittings

If you're restoring or maintaining a carbureted vehicle that runs on a 6-volt electrical system, this AUTOKAY electric fuel pump provides a straightforward replacement or emergency spare. It’s designed for inline installation with 5/16" inlet and outlet fittings and supports both positive- and negative-ground setups. The unit works with unleaded and alcohol-blended fuels and is offered as a current production part rather than old-stock components.

Will this pump fit my Buick or other classic 6V carbureted cars?

Yes — the AUTOKAY pump is a universal inline model intended for carbureted engines that use a 6-volt system. It fits many older Buicks and other classic vehicles when the fuel delivery requirements and hose sizes match.

• Compatible with carbureted models on 6V electrical systems.
• Recommended for Buick models from the late 1920s through early 1930s when specifications match.
• Uses 5/16" inlet and outlet hose connections for common classic fuel lines.
• Works in both positive and negative ground setups.

How much pressure and flow can I expect from this pump?

The pump produces around 5–8 PSI, suitable for most gravity- or carburetor-fed systems that require low to moderate fuel pressure. It’s intended to assist or replace mechanical pumps in systems that don’t demand high-pressure fuel injection performance.

• Rated output: approximately 5–8 PSI, appropriate for carbureted engines.
• Designed for steady low-pressure delivery rather than high-pressure injection use.
• Works as a primary pump or an auxiliary/assist pump depending on your setup.
• Compatible with ethanol-blended and unleaded gasoline formulations.

Is installation difficult and what’s included in the kit?

Installation is straightforward because this is an inline-style pump — you splice it into the fuel line between the tank and carburetor. The kit ships complete with the pump and basic mounting and connection parts shown in the product images, making it suitable for mechanics and hobbyists alike.

• Simple inline design: cut existing line and insert pump between tank and carburetor.
• Includes one pump assembly and necessary hardware as pictured in the listing.
• Electrical terminals ready for 6V connection; works with positive or negative ground vehicles.
• Lightweight and compact for flexible mounting locations near the fuel line.

Who is this for: This AUTOKAY 6V inline electric fuel pump is intended for owners and restorers of classic cars with 6-volt electrical systems that use carburetors — especially those seeking a modern, reliable replacement for an aged mechanical pump or an emergency standby unit. It suits hobbyists, restoration shops, and anyone maintaining a vintage Buick or related model that requires low-pressure fuel delivery. Avoid using this unit on modern high-pressure fuel injection systems; confirm hose size (5/16") and pressure needs before purchase.
