DTMAP 12V Universal Electric Fuel Pump — 5–9 PSI Low-Pressure 30 GPH Inline Pump for Carbureted Engines

This compact 12V pump is built as a drop-in solution for carbureted engines and low-pressure transfer needs. Designed to replace OE E8012S and to suit a wide range of vehicles and equipment, it pairs straightforward plumbing with steady flow to reduce vapor lock and maintain consistent fuel delivery. The unit's replaceable barb fittings and rugged construction make it practical for DIY mechanics and professional installers alike.

How does this pump fit into my vehicle's fuel system?

The DTMAP pump is an inline, low-pressure electric fuel pump intended for carbureted systems or as an external transfer pump. It installs between the fuel tank and carburetor or can be used as an auxiliary booster. Use appropriate fuel-rated hose and clamps for a secure connection.

• Inline configuration: fits between tank and carburetor or fuel filter.
• Barb size: 5/16" hose inner diameter with 3/8" barb-head section for a snug seal.
• Voltage: designed for standard 12V systems in cars, trucks, ATVs and boats.
• Replaces OE part E8012S for many older carbureted setups.

What performance can I expect from this 5–9 PSI, 30 GPH pump?

Expect a steady low-pressure output useful for carburetors and fuel transfer duties rather than high-pressure EFI systems. The rated flow of 30 GPH (113 LPH) supplies enough fuel for most small to mid-size engines running carburetors and helps prevent vapor lock under typical conditions.

• Pressure range: 5–9 PSI for carburetor compatibility.
• Flow rate: 30 GPH (113 LPH) steady delivery under normal load.
• Current draw: approximately 1.0–2.0 A, minimal electrical load.
• Suitable for gasoline and diesel transfer tasks (not a high-pressure EFI pump).

How do I install and maintain the DTMAP electric fuel pump safely?

Installation is straightforward with basic tools: mount the unit securely, run fuel-rated hose to the inlet and outlet, and wire it to the 12V supply with an inline fuse. Routine checks of hose clamps and electrical connections will keep the pump reliable and reduce the risk of leaks or failure.

• Mount: vibration-isolating bracket or secure clamp in protected location.
• Plumbing: use 5/16" fuel hose and proper clamps for the barb fittings.
• Electrical: 12V connection with inline fuse and correct polarity.
• Maintenance: inspect hoses, fittings, and mounting annually or with each service.

Who is this for? The DTMAP 12V Universal Electric Fuel Pump suits DIY mechanics, restoration projects, and owners of carbureted cars, trucks, motorcycles, ATVs, and small boats that require a reliable low-pressure inline pump. It is also useful as an external fuel-transfer pump for diesel and gasoline where high-pressure EFI capability isn't needed. Choose this pump if you need a compact, replaceable-barb inline unit that meets IATF 16949 quality standards and includes a one-year or 30,000-kilometer warranty for peace of mind.
