Just installed a new 255 Walbro Fuel pump and now I am getting a funny noise. It alsmost sounds like very light insect buzzing or the sound of Electricity. it is not really loud but is noticable and I am wondering if it is just normal sounds from the pump or if something is wrong. it really only whappens when I get on the throttle or when I let off it.

thats normal.

 

Very normal. Mine sounded like a turbine engine all summer when it gets hot after driving hard. Now that the weather is cooler, I do not hear it anymore.

I just hope despite the noise that it performs well over the long term. I don't know much about Walbro and their reliability compared to Denzo and OEM quality. I don't want it taking a dump after X amount of years.

I know the GMC Syclones and Typhoons are running them aftermarket and those vehicles have been around over 10 years. Anyone know?

 

Very normal to have a buzzing sound.

 

Normal

 

Mine is silent.

 

It is normal for the Walbro to have some sort of a whine to it.

 

thanxs guys, now if I could only sort out my BOV lol

 

your not driving hard e'nuff
