the fuel pump is on a greddy turbo. today, i got my a/c freon removed and refilled because a great amount escaped during the installation. this is the first time i use a/c with the turbo. so, now the fuel pump whinning is very loud than it was before. i'm talking super loud like those dog whistle. when i turn off the a/c, the sound remains. is there something wrong here or is that normal when a/c is used???

 

dunno about the ac thing, but walbro pumps have always been loud

 

I've noticed pumps get louder as the pressure gets higher, is the car running ok? perhaps you have a block fuel line.

the car runs fine. got it tuned w/ hondata and everything was professional installed. i hope nothing bad happens because this turbo project is expense as it is. another thing is the a/c isnt even that cold. it feels like wind bleeze not a chilly breeze like before when i remember it. either something is wrong with the a/c or that asian auto shop jacked me on the freon. never will i go there again. they left greasy dirty hand prints inside and outside of the car. i should've known right away when oil were spill everywhere on the floor. anyone know if kragen or pep boys have free gauge testing to see what's my pressure?
