Well I just put in the walbro 255 fuel pump and i got my ecu flashed for it by dyno flash. Now i hear a loud noise coming from under the car only when its running and i kno you here the pump inside the car i kno thats normal the noise under the car is like a high pitch noise is that normal ???? and when i was testing it around top rpms feels like its dying out is this due to the fuel pump not working properly ???? i kno i installed it right its a real easy install mainly plug and play but if anyone has suggestions let me kno i was thinking maybe spark plugs but some feedback will be helpful thanks everyone

 

bump???? anyone

 

Well...I don't know about your dying out problem...I don't have that...but the whine is rather loud and it's more noticable then I thought it would be so that's probably how it's supposed to be unless it's HIGHLY annoying.

 

Do you hear it outside of the car as well or just inside ? thanks bro

 

No...if I remember correctly you don't. I can't say 100% for sure though...my car is in storage right now

 

hmmm thats wierd sometimes i dont hear it and sometimes i do here outside. but inside the car it isnt that loud theres a little whine but sometimes i get out of the car iand its extremely loud whine

 

bump anyone else thanks ????

 

I think you may have misinsatled the pump - did you transfer over the white platic ring to the new pump ?

 

White plastic Ring can you help me out maybe i didnt see that thanks ??? if i recall i remember there is the rubber piece that came with the kit but i used the oem one thanks al

 

you mean the ring that clamps down and tightens it ????? if so yes i did take that out from the old one on to the new one

 

nope i think al means the white grommet that sits under the o-ring. Walbro's kinda sound like a hairdryer under your back seat

 

I have had no problems with my Walbro fuel pump.

 

where is this part on the old fuel pump thanks guys

 

when i did the install yesterday...after i pulled out the stock pump, the white grommet was still on the oulet nipple, and i popped it off. BTW be carefull pulling the pump out of the housing, i accidently pulled it out too much and popped off the wires

 

so let me ask you something on one side of the walbro looked like it was a vavle type of inlet is that where this o ring goes on ?? thanks
