Precision Fuel Delivery for LS Engine Performance

Its robust design maintains consistent pressure under wide throttle openings, preventing lean conditions during spirited acceleration or sustained high load. This level of supply stability is essential for EFI setups, where precise volumetric fuel delivery directly influences combustion efficiency and power output. By matching pump capacity to LS engine demands, the system delivers smooth throttle response from idle through peak rpm.

Tank straps, gaskets and filler neck hardware align with factory holes to reduce trial and error installation, saving hours in the shop. The sending unit is calibrated to the original vehicle fuel gauge, restoring accurate fuel level readings in the dash. With this precise fitment the entire fuel system can be dropped in place and bolted down in minutes.
