Why Must You Choose a Good Quality Fuel Pump Test Bench?

Fuel pump is an essential component because it plays a very vital role of moving fuel from the car’s tank to the engine. Deep within that fuel pump is a little yet incredibly significant piece known as the fuel pump plunger. When it wears out, you simply replace it and this will give your fuel pump a new lease of life.

What is a Fuel Pump Plunger?

Fuel pump plunger supply is a rail that moves backwards and forwards within the body of the fuel pump to generate pressure in the pump chamber. It has a seal on the end that runs tightly in a bore to produce this pressure with little loss. During the intake stroke, it sucks fuel into the pump chamber.

After several years of usage the seal and bore gets worn and the fuel starts leaking back and thus reducing the efficiency of the pump. One of the easiest remedies that could be used is to change a bad plunger with a new one with the hope that the pump will function normally and that the pressure will also be normal. Original and high quality replacement plungers can be obtained from original equipment manufacturers such as Wunfa Group.

Fuel Pump Health Importance

A weak fuel pump is commonly responsible for a host of driveability and performance issues. Symptoms include:

       Having an issue with power loss under load

       Rough idle

       The check engine light is for a lean fuel condition

 Test Bench Verification

It would be a shot in the dark for Ries to replace the pump plungers without subjecting them to a comprehensive functional test. Wunfa Group employs Test Stands to check the functionality of rehabilitated pumps and other replacement parts such as plungers.

These test benches mimic real-world operational scenarios in the fuel system while recording the output parameters. It is thus possible to assess performance criteria such as fuel flow volume, pressure, voltage draw among others right at the bench. This is done to ensure that refurbished or repaired pumps meet the OE level of quality before they are released in the market.

Wunfa Group uses high precision components in conjunction with verification testing to supply quality fuel pump test bench parts that ensure peak engine efficiency. This is important for driveability because vehicles need the right fuel to operate optimally; for fuel economy because it determines the kind of fuel efficiency that a car will have and for future avoidable repair costs because using the wrong fuel damages vehicles and puts them at risk of expensive repairs in the future. Hence, common parts such as plungers, if well maintained, will go a long way in the fuel system.
