DTMAP 12V Universal Electric Fuel Pump 5–9 PSI 30 GPH — Inline Replacement for Carburetors, 5/16" Barb

DTMAP 12V Universal Electric Fuel Pump is a low-pressure inline fuel pump that delivers 5–9 PSI and about 30 GPH (113 LPH) for carbureted gasoline and diesel transfer applications.

This compact 12V pump is built as a universal replacement for E8012S-style units and is engineered for steady, low-pressure fuel delivery to carburetor systems, small engines, ATVs, motorcycles, boats and light-duty vehicles. With 5/16" barb inlet/outlet (3/8" at the barb head), a nominal current draw of 1.0–2.0 A and a flow rating around 30 GPH, it’s intended for inline installations, fuel transfer tasks and as a booster in low-pressure fuel setups.

How does this pump perform in everyday use?

The pump maintains a consistent low-pressure output between 5 and 9 PSI and a flow of approximately 30 GPH, which keeps carbureted engines fed without the high pressures of EFI systems. It runs on standard 12V vehicle electrical systems and has a modest current draw, making it suitable for extended use in many accessory installations.

• Operating pressure: 5–9 PSI for carbureted systems.
• Flow rate: ~30 GPH (113 LPH) for steady fuel delivery.
• Current draw: about 1.0–2.0 A under normal load.
• 12V input compatible with most automotive and marine batteries.

Will this fit my engine and fuel lines?

This model is designed as a universal 12V inline pump and replaces OE number E8012S in many applications. The inlet and outlet use a 5/16" barb (barb head measures 3/8"), so you may need standard hose clamps or short adapters to match your existing fuel hose sizes.

• Barb inlet/outlet: 5/16" (barb head 3/8").
• Suitable for carbureted gasoline engines and diesel transfer roles (not for high-pressure EFI injection).
• Common fitment: cars, trucks, motorcycles, ATVs, boats and small engines.
• Replaces: OE E8012S-style pumps in many low-pressure systems.

How should I install and maintain this inline fuel pump?

Install the pump inline between the tank and carburetor following the vehicle’s fuel routing, ensuring correct flow direction and secure hose clamps on the 5/16" barbs. Mount it on vibration-dampening brackets or rubber isolators, keep wiring fused and routed away from heat sources, and periodically inspect hoses and clamps for leaks or wear.

• Mount with vibration isolation and correct flow orientation.
• Use inline fuse on the 12V power lead per vehicle wiring standards.
• Check hose clamps and hoses for tightness and degradation regularly.
• Not intended for high-pressure EFI systems—use for carbureted or transfer applications only.

What quality and warranty support does DTMAP provide?

The pump is manufactured under IATF 16949 quality standards for automotive suppliers and is backed by a limited 1-year or 30,000-kilometer warranty. That coverage gives you a standard level of protection against material or manufacturing defects when used in recommended applications.

• Built to IATF 16949 automotive manufacturing standards.
• Warranty: 1 year or 30,000 kilometers for eligible defects.
• Designed for durability in low-pressure fuel service and transfer roles.

Who is this for? This DTMAP 12V low-pressure electric fuel pump is best for hobbyists, mechanics and owners of carbureted vehicles who need a reliable inline replacement or booster pump. It’s also useful for small boats, ATVs and equipment requiring a steady 5–9 PSI supply or for portable fuel transfer tasks, provided the installation follows manufacturer and safety guidelines.
