When fuel pressure is small, a scan tool will exhibit extended-time period fuel trim is considerably constructive on a regular basis and short-phrase fuel trim will get to maximum on acceleration (fuel trims max out at 25%). Nonetheless, a vacuum leak can produce equivalent fuel trim readings.

Port and Helix pumps are mostly Employed in maritime diesel engines on account of their simplicity, trustworthiness, and its power to be scaled up in proportion for the engine dimensions.[four] The pump is analogous to that of the radial piston-type pump, but as an alternative to a piston it's a machined plunger which has no seals.
