Nissan TD42, SD33, QD32, RD28 (early)
Toyota 1HZ, 1HD-T, 1HD-FT.
Various Toyota, Mitsubishi, Mazda, and Isuzu fuel pumps use the same size of spring.
This is a medium-duty spring to suit most stock applications as well as mildly modified vehicles using aftermarket turbochargers running higher boost pressure, larger intercoolers, intake and exhaust upgrades.
The effective control range is 3-20psi at the lowest star wheel position and maximum travel.
There is no one-size-fits-all when it comes to fuel compensator components. The shape of the pin, the pre-tension placed on it from the spring, size of the turbo all play a part in how the vehicle will perform.
Please use an experienced diesel tuner to set the pump up correctly if you are not sure how or why to adjust the internal components in the diesel pump.
Custom and OEM fuel compensator pins are also available. See our range here – https://www.tillix.com.au/product/zexel-td42-compensator-fuel-pin/
