evening guys, right getting seriously annoyed now as im on the second walbro 255 pump and looks like ill be going for a third! first one lasted literally a year before starting to make some absolutely hideous noise which was certainly not normal, bought a new one all was ok until now, this one is now making a horrible noise aswell! its literally been on the car for 3-4months i know all the usual, dont let petrol run low etc which i never do. anyway if you look at the link you will see what i meen about the noise its making, its been very loud and abit jumpy and as of today its been making this noise! opinions would be great
