After driving for a while (over 30 minutes usually, and not hard driving) there is a nasty whine coming from the back of the car. It is a constant pitch regardless of speed, and can be heard inside and outside. I'm 99% sure it's the fuel pump.

It's been doing it since I bought the car nearly 2 months ago, no other issues. I have been told that it's an uprated fuel pump (possibly a Walboro but not 100% sure).

Should I be worried, or is it pretty normal? Will it eventually give up and should I fit a new one as a preventative measure?

 

noises mean problems so replace before it dies on you in the middle of nowere..

 

If its been doing it since you got it, and its an uprated Walbro or similar, I wouldnt worry too much as the whining noise is quite common with these.

I have a Walbro 255lph one on my classic and you can hear it whining away from the rear of the car

 

Ive a walbro and i only hear it when it primes when i switch on the ignition, silent the rest of the time

 

na i have a walbro 255 in my classic and i would say its pretty loud when i first got it it i thought no way theres something wrong as you can hear it outside the car so i replaced it with a brand new walbro 255 and sounds exactly the same no change car runs mint !!

 

My walbros quiet as a whistle, can be heard on full woot and priming only.
