Fuel Pumps
Fuel Pumps – ASNU fuel systems and injectors are designed to be used in conjunction with standard grades of road-pump fuels, and certain race fuels with lubricant and corrosion packs (please enquire for details of tested and compatible race fuels) or vist the ASNU Shop.
The use of pure Ethanol, Methanol or other chemicals mixed in combination with standard pump gas or race fuels is not advised and will invalidate any warranty on all of our systems. Fuels with more than 50% ethanol, even with lubricants, will greatly accelerate wear and shorten system life as well as reducing the service life on any filters.
Our fuel pumps products are compatible with certain methanol blends containing an appropriate lubricant pack and E85 for race or drag events. When used with fuels that have Ethanol contents over 50% or fuels with a methanol content, the fuel system must be drained and flushed between events to prevent irreversible damage.
On a GDI system, the fuel is injected directly into the combustion chamber at a much higher pressure than manifold systems, up to 200 bar. These systems now require fuel pumps and injectors made of stainless steel and must be capable of performing at a much higher specification than ones seen on previous manifold injection systems. It delivers very precise quantities of fuel at extremely high pressures and in short periods of time, in some cases, for fractions of a millisecond.
