There is more than a bad production run.
Walbro did have an issue with a certain model 255 pump, but not all.
There quite a few variations in circulation.
There are also counterfeit pumps (even with Walbro stamps) out there that have less than a spectacular reputation.
Since you are in Canada, I suggest you contact Racetronix directly.

i have a walbro 255 and im having issues too. When i turn the key ON i have only 15 psi at the rail and it goes to zero in about ten seconds. if i turn the key like 3 times in a row il have 55-60 psi but it drops very fast. could this be a pump problem or possibly the regulator or internal fuel leak in tank?? And btw i have a 2000 z28 ls1

I am having issues with a walbro 255 I just put in my truck. Fuel pressure is dropping to zero when I excelerate, after running for a little wile. The pump is not hot and if I shut the truck off for a minute it runs normal. Anyone think it may be a problematic pump?
