DTMAP 12V Low-Pressure Inline Fuel Pump — 28 GPH (106 LPH), 5/16" Barb, 2–3.5 PSI for Carburetors and Fuel Transfer

DTMAP's 12V Universal Low-Pressure Inline Fuel Pump is a compact, 28 GPH electric pump engineered to supply steady fuel flow (2–3.5 PSI) to carbureted gasoline and diesel transfer applications. This inline fuel pump is designed as a simple, reliable way to move fuel in 12V systems where high-pressure electronic fuel injection is not required. It suits carburetor-fed engines, small equipment, and fuel-transfer tasks — offering a controlled 28 GPH (106 LPH) flow while drawing only 1–2 A. Built with universal 5/16" barb inlet and outlet dimensions (3/8" at the barb head) and manufactured under IATF 16949 standards, it targets durability and ease of installation for hobbyists and professional mechanics alike.

How does this pump perform in everyday equipment?

The DTMAP inline pump supplies a steady low pressure ideal for carbureted engines, lawn mowers, small boats, ATVs, and auxiliary fuel-transfer roles. Its consistent 2–3.5 PSI output minimizes vapor lock risk and provides reliable priming without over-pressurizing carburetor float bowls.

• Flow rate: 28 GPH (106 LPH) for continuous feed or transfer tasks.
• Operating current: 1–2 A keeps power draw minimal on 12V systems.
• Pressure range: 2–3.5 PSI suitable for carburetor and low-pressure diesel transfer.

Will it fit my vehicle or equipment?

This pump was designed with universal fitment in mind. The inlet and outlet accept 5/16" fuel hose (barb head measures 3/8"), and its 12V electrical requirement matches standard automotive and small-engine systems.

• Universal compatibility with most 12V engines and small equipment.
• Barbed fittings for secure hose attachment to 5/16" fuel line.
• Compact inline form factor for straightforward placement along existing fuel lines.

How is the pump best used — can it handle gasoline and diesel?

Use this pump primarily as a low-pressure electric fuel pump for carbureted gasoline engines or as a fuel transfer pump for diesel systems. It is not intended for high-pressure direct-injection EFI systems but performs well as a booster, inline replacement, or transfer unit.

• Compatible with gasoline for carbureted setups and diesel for transfer/auxiliary duties.
• Not rated for high-pressure EFI applications or pressurized injection rails.
• Common uses: booster pump, inline replacement, and portable transfer pump.

What quality and support come with the pump?

DTMAP manufactures this pump under IATF 16949 quality standards for automotive components and backs it with a one-year or 30,000-kilometer warranty. The unit’s modest electrical draw and sealed construction help extend service life when installed correctly and maintained.

• IATF 16949 production quality for automotive-grade consistency.
• Warranty: 1 year or 30,000 km for consumer confidence.
• Low current draw and sealed body to resist common environmental stresses.

Who is this for: This DTMAP pump is aimed at DIY mechanics, landscapers, marine hobbyists, and workshop technicians who need a dependable, low-pressure 12V fuel solution for carbureted engines, auxiliary fuel transfer, or light-duty booster duties. If you require a compact inline pump that’s easy to install, conserves electrical power, and provides steady low-pressure flow, this unit is a practical choice — just avoid using it on high-pressure EFI injection systems where higher-spec pumps are required.

FAQ

Q: Can this pump be used on EFI engines?

A: No. This DTMAP pump is low-pressure (2–3.5 PSI) and not suitable for high-pressure EFI injection systems.

Q: What hose size fits the inlet and outlet?

A: Use 5/16" fuel hose on the inlet and outlet; barb head measures 3/8" for secure attachment.
