Automotive inline fuel pump designed to restore reliable fuel delivery for 12V petrol and diesel systems, promising steady flow and easy fitting. Weekend mechanics and small workshops gain confidence from quicker starts and fewer fuel delivery headaches. Is the MAIL MORE Electric Fuel Pump the universal 12V solution your engine needs?

⚡ At a Glance
  • Flow Rate: Approximately 80–90 L/h at 12V with an output pressure of 4.5–7 PSI
  • Best for: Carburettor-equipped cars, vans, light trucks, lawnmowers and small generators
  • Not ideal for: High-pressure direct-injection or manufacturer-specific OEM fuel systems

Inline 12V self-priming pump with metal construction and a copper-wound coil. Supplied with mounting hardware and hoses for straightforward replacement jobs.


Reliable Starting and Steady Supply - thanks to self-priming 12V operation

Self-priming action draws fuel without manual priming and maintains output pressure in the 4.5–7 PSI range, delivering roughly 80–90 litres per hour at 12 volts. The unit runs at about 1.5 amps under typical conditions.

Faster cold starts and consistent fuel flow for carburettor systems, reducing misfires and hesitation during tuning and everyday use.

Longer Service Life - with metal body and pure copper wire coil

Metal gasoline pump houses a pure copper wire coil for stable electromagnetic performance, which the manufacturer states gives a lifespan four to five times longer than many comparable diesel engine pumps. Robust metal construction resists heat and vibration better than plastic alternatives.

Fewer replacements and greater durability in workshop or frequent-use scenarios, making the unit suitable for regular maintenance tasks.

Quick Fit Replacements - thanks to compact inline format and included kit

Compact inline layout with 8mm inlet/outlet diameter and a hose size of 5/16" suits standard fuel lines, and the supply includes two rubber fuel pipes, four clips and two fixing nuts and bolts. Small, lightweight profile allows fitting into tight engine bays.

Straightforward swap for failing inline pumps, ideal for roadside repairs or home garages without specialist tools.
