View Product Fuel Pump Assemblies Bosch supplied the industrys first fuel injection system with a high pressure electric fuel pump in 1967. Since then, Bosch has stood at the forefront of fuel system technology, providing fuel pumps to virtually all vehicle manufacturers. Bosch Fuel Injectors Catalogue Full Load SavingCompared to conventional fuel pumps, Bosch Pumps deliver 30 higher efficiency and the precise fuel supply required for a partial or full load saving fuel and reducing CO2 emissions. View Product High-Pressure Pump (HPP) The high-pressure pump is responsible for compressing the fuel supplied by the electric fuel pump to the pressure required for high-pressure injection up to 20 MPa (200 bar).

Making this early truck injector unique is its Multec 2 connector. Just about the time we get comfortable with a certain injector, a new version debuts and we have to learn a new set of parameters. However, for performance engine builders, EFI swappers, and inveterate engine tinkerers, this ever-expanding range of fuel injectors offers both opportunity and confusion. ![]() Or, you could just listen to your brother-in-law he knows everything, right. We will focus on all the important injector fitment specs such as overall length, O-ring sizes, and electrical connectors. Weve even delved into adapters that will allow you to install a late model injector, for example, in an earlier truck engine, as well as info on the confusing array of electrical connectors. The connector part of this story would not be too bad if the industry could stick to one name but with multiple names for each connector it can get perplexing. Its like having a friend whos name is Bob on odd days and Fred on even days. From left to right: original Bosch Jetronic EV1, the tall LS1 style followed by the early LS truck injector, and on the far right the late LS3 EV6 style. The one missing version is the late truck injector that is the same height as the early truck LS piece but using the EV6 electrical connector. If there is sufficient demand, we can easily create a Part II and add that material along with descriptions of the differences between high and low impedance injectors and why thats important and how to calculate flow rate with different fuel pressures. Combined with the accompanying images, the chart is probably the easiest way to differentiate and make sense of all the different GM injectors. We placed this Holley LS1 LS2 fuel rail to a cathedral port TrailBlazer SS intake manifold using Z-shaped aluminum mount adapters. Aeromotive does not recommend mixing and matching fuel rails due to the possibility of a high-pressure fuel leak. Well begin with the earliest Bosch style multi-point injectors that first appeared in the GM TPI engines around 1985. These injectors are physically the largest and tallest of all the GM injectors. These units are becoming less popular now mainly because they dont deliver the high flow rates now demanded by todays more powerful engines. The earliest reference is the Jetronic the Bosch name for its early fuel injection system. ![]() Right away, this becomes mystifying with three different ways to describe this electrical connector. This injector was used all the way up into the mid-2000 model-year in certain vehicles. This unit is much slimmer and slightly shorter than the early Bosch injectors, taking up much less real estate. These early injectors were used in the passenger car LS1 applications and while appearing more modern, retain the EV1 or MinitimerJetronic connector. Unfortunately, GM didnt carry this injector over to the trucks, choosing instead to go with an entirely different injector.
