DTMAP 12V Inline Fuel Pump 35 GPH (132 LPH) 5–9 PSI Low-Pressure 5/16" Barb for Carbureted Engines and Diesel Transfer

DTMAP Universal 12V inline fuel pump supplies low-pressure, steady fuel flow (35 GPH / 132 LPH) for carbureted gasoline engines and diesel transfer applications.

This compact electric pump is built to fit a wide range of 12V systems where low pressure and reliable flow are required. With a 5–9 PSI operating range, 35 GPH output, and 5/16" barb inlet/outlet (3/8" at the barb head), it serves as a drop-in solution for carbureted cars, trucks, motorcycles, lawn and marine motors, and as a transfer pump for diesel equipment. The unit draws just 1.0–2.0A and is manufactured under IATF 16949 standards, backed by a 1-year or 30,000 km warranty.

How does this pump perform in everyday vehicles?

The DTMAP pump provides consistent low-pressure delivery that keeps carburetors fed without over-pressurizing. Its steady 35 GPH flow helps prevent vapor lock and reduces fuel surge under normal driving and idle conditions. The pump is not designed for high-pressure electronic fuel injection systems.

• Operates at 12V with 5–9 PSI output to suit carbureted plumbing
• Flow rate of 35 GPH (132 LPH) for steady delivery
• Low current draw (1.0–2.0A) for efficient operation

Can I use it with diesel and non-car systems?

Yes — the pump can handle both gasoline and diesel for low-pressure tasks, such as fuel transfer or as an external booster on diesel equipment. It should not be used in place of a high-pressure EFI pump. For small engines, boats, ATVs, and equipment with carburetors or gravity feed systems, it is a versatile option.

• Compatible with gasoline and diesel for low-pressure applications
• Suitable for motorcycles, ATVs, marine outboards, lawn motors, and generators
• Not suitable for high-pressure direct injection EFI systems

What are the physical and installation details I should know?

The pump features 5/16" inlet and outlet barbs (3/8" where the barb head flares) for common fuel hose sizes, making hose attachment simple with clamps. It is lightweight and compact for easy inline placement close to the tank or between the tank and carburetor. Wiring requires a 12V supply and basic relay/fuse protection as part of a safe installation.

• Barbed 5/16" inlet/outlet (3/8" at barb head) for standard fuel lines
• Compact inline design for underbody, engine bay, or near-tank mounting
• Install with fuse or inline relay and secure mounting to limit vibration

What durability and warranty coverage does it offer?

Built under IATF 16949 quality controls, the pump is engineered for reliable service life in typical low-pressure fuel duties. Expect consistent performance when installed and maintained correctly, and take advantage of the included 1-year or 30,000-kilometer warranty for added confidence. Replacement or warranty service terms apply per the seller’s policy.

• Manufactured to IATF 16949 standards for quality assurance
• Backed by a 1-year or 30,000 km warranty
• Designed for steady, long-term low-pressure operation when maintained

Who is this for? Mechanics, hobbyists, and vehicle owners who operate carbureted engines or need a dependable low-pressure transfer pump will find this DTMAP unit useful. It’s aimed at people restoring classic cars, maintaining small engines, outfitting boats or ATVs, and anyone needing a compact 12V inline pump that delivers steady flow without the complexity of high-pressure EFI equipment.
