DTMAP 12V Inline Fuel Pump 30 GPH Low-Pressure 5–9 PSI — 5/16" Barb for Carbureted Engines

DTMAP Universal 12V inline fuel pump is a low-pressure (5–9 PSI), 30 GPH electric replacement designed for carbureted gasoline and diesel transfer use.

This compact, serviceable fuel pump supplies a steady, low-pressure flow for carburetor engines and fuel-transfer tasks. With 5/16" barb inlet and outlet (3/8" at the barb head), 12V input, and a 30 gallons-per-hour (113 LPH) flow rating, it’s built to swap into many small engines and aftermarket fuel systems. The unit is rated for 1.0–2.0A draw and is manufactured to IATF 16949 standards, carrying a one-year or 30,000-kilometer warranty for added confidence.

How does this pump perform in everyday equipment?

The pump provides a consistent low-pressure output (5–9 PSI) and a steady 30 GPH flow, which helps maintain smooth engine running in carbureted applications and reliable fuel transfer. Its modest current draw keeps installation simple on 12V systems without stressing electrical circuits. The pump’s design minimizes vapor lock and reduces fuel surging when installed inline.

• Operate pressure: 5–9 PSI for carburetor-friendly delivery
• Flow rate: 30 GPH / 113 LPH for continuous supply
• Current draw: 1.0–2.0A compatible with standard 12V wiring
• Barbed 5/16" inlet/outlet (barb head 3/8") for common fuel tubing

Will this fit my vehicle or machine?

DTMAP engineered this as a universal inline pump for most 12V small engines and accessory fuel systems. It’s commonly used in lawn mowers, motorcycles, ATVs, boats, and older cars with carburetors, and can also serve as a low-pressure transfer pump for diesel. However, it is not a substitute for high-pressure EFI pumps used on modern fuel-injected engines.

• Replacement compatibility: Replaces OE E8012S
• Suitable for: carbureted gasoline engines and low-pressure diesel transfer
• Not for: high-pressure electronic fuel injection systems
• Universal fit: works with common 5/16" fuel line tubing

How do I install and maintain it?

Installation is straightforward: mount inline with correct fuel line orientation, secure the 5/16" hoses to the barbs, and connect to a fused 12V source. Periodic checks of hose clamps, electrical connections, and strainer condition keep the pump performing reliably. The pump housing and serviceable design allow replacement when wear occurs instead of complex overhaul.

• Mount inline between tank and carburetor or as a transfer pump
• Use clamps on 5/16" barbed fittings for leak-free sealing
• Wire to a fused 12V supply and check polarity before power-up
• Inspect hoses and electrical connections during routine maintenance

What quality and warranty protections are included?

Manufactured under IATF 16949 quality guidelines, this pump meets automotive-grade production controls for durability. DTMAP backs the unit with a one-year or 30,000-kilometer limited warranty, giving added reassurance for replacement projects and aftermarket installs.

• IATF 16949 production standard for consistent build quality
• One-year or 30,000-kilometer limited warranty included
• Robust low-pressure design to reduce early failure modes
• Serviceable mounting and electrical connections for ease of replacement

Who is this for: This DTMAP 12V universal inline fuel pump is aimed at DIY mechanics, small-engine technicians, and owners of carbureted vehicles or equipment who need a dependable low-pressure replacement. It’s well suited for those restoring classic cars, maintaining lawn and garden machines, outfitting boats and ATVs, or installing a simple fuel-transfer solution—anyone requiring a reliable, compact 12V fuel pump that replaces part E8012S.
