About this part
WLTL13800A is supplied as a remanufactured replacement fuel injection pump. Cross-reference numbers: WLTL13800A, 104640-0991, 104640-0992, 104740-0992, NP-VE4, 10F2150LNP2097. Application recorded for this part: VE.
This unit sets both quantity and timing for every cylinder. Modern engines depend on that timing being accurate to well under a degree, so internal wear that would once have been tolerated now shows up as smoke, noise and failed emissions checks.
Typical indicators are progressively harder starting, particularly when hot, reduced power, smoke under load, erratic idle, and fuel dilution in the sump — the last one should always be investigated immediately.
Check supply pressure at the pump inlet and look for air in the clear line before assuming internal wear. Plenty of pumps get replaced for a blocked filter or a suction leak that costs a fraction to put right.
Key points: align to the timing marks rather than forcing the drive, prime before cranking, renew seals, confirm adequate supply pressure from the lift pump, and bleed the system fully. Skipping any of these is where most comebacks originate.
Rebuild process: full teardown and measurement first, then replacement of all wear components, machining back to specification where required, followed by calibration and bench testing. The difference between this and a cleaned used part is the measurement and test record — we hold every unit to the specification for the part number, not just to 'it runs'. Test sheets available on request, and every unit ships with a 12-month warranty.
