Una pompa del carburante si trova di solito nella maggior parte dei veicoli oggi. Esistono due tipi di pompe del carburante, il meccanico e l'EFI (Iniezione elettronica del carburante). I motori a carburatore richiedono un certo livello di pressione in modo che il flusso di carburante sia costante e nei momenti di emergenza, veloce. Mechanical fuel pumps are usually found outside the fuel tank, while EFI units are always located inside the tank.

How To Pick A Fuel Pump For Carb?
While pressure is key to the success of an engine’s performance, too much pressure will create a rich and rough ride, while under pressure will lead to misfires and a stall. That is why all modern vehicles using EFI connect the EFI to the vehicle’s computer system, or ECU (Electronic computer unit).
The advantages of an electric fuel pump are how it reduces fuel consumption through monitoring the flow and use of the fuel in line with the engine and the whole motor tune. Modern vehicles come with a “tune” that means they are programmed to perform within certain parameters. One of these parameters is fuel consumption that is regulated together with the other engine functions. Through proper regulation and monitoring, modern engines are more fuel-efficient than older models that do not have an ECU.
This article presents the top-rated Holley models, which are considered to be the leading fuel pumps in the aftermarket world. Apart from fuel pumps, Holley manufactures high-performance carburetors, manifolds, superchargers, water pumps, and throttle body fuel units for stock and performance racing applications. The Holley site is split between Holley Engineering and MSD Engineering. The MSD site is a re=search and development site dedicated to improving systems; the Holley site is a mass production facility dedicated to producing top-rated products. Each station in the production processed is manned (womanned) by a qualified engineer, as such, every Holley product is as close to perfection as you will get.
There are four types of Holley Pumps, the stock models and the performance models designated red (97GPH), blue (110GPH) and black (140GPH). The red models use a low flow rate that fits most stock and small performance upgrades; they don’t come with regulators. The blue and black models are for upgraded vehicles and provide a regulated high flow rate and higher psi level.
Some of the models will work with mixed gasoline or diesel fuels, when choosing a pump, make sure you use it for the designated fuel types.
