About this part
22100-17580 is supplied as a remanufactured replacement fuel injection pump. Cross-reference numbers: 22100-17580, 096000-8570. Application recorded for this part: Fits Toyota — 1HD.
Every injection event depends on this pump producing pressure at exactly the right moment. Because it also carries its own lubrication, poor supply pressure and fuel dilution do disproportionate damage — which is why the supply side should always be checked alongside the pump itself.
Look for extended cranking, especially hot, poor throttle response, smoke across the rev range, fluctuating idle speed, and a gradual rise in consumption that cannot be explained by duty cycle.
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.
Fitting notes: timing is everything here. Set the pump against the engine's timing marks rather than forcing anything, prime thoroughly before cranking, and check that the lift pump is delivering adequate supply pressure. Also replace the mounting seal and confirm there is no air left in the system before the first start.
How we build it: the unit is fully disassembled, cleaned and measured, not simply resealed. Wear items — seals, springs, and where clearance is out of specification the plunger and barrel or nozzle assemblies — are replaced rather than reused. Sealing faces and bores are re-machined back to original clearances, then the unit is calibrated and run on a bench with delivery, return flow, opening pressure and leakage recorded. Anything outside specification does not ship. Test sheets for your specific units are available on request. Covered by a 12-month warranty.
