I am about to put the fourth fuel pump in my MK3 Golf (1.4 ABD Engine) in its 24 year history.

I pulled the last two failed pumps apart and found that tiny particles of something had jammed the impellers in both cases, but particles of what I couldn't say but I'd put a new canister filter on each time I put a new pump on?

It's got me guessing as the tank is plastic as I think are the fuel lines and I try not to run too low on petrol, the only thing I have doubts about is the system by which the tank is vented via a valve and a carbon filter and wonder if this is where the bits are coming from, and I'm not talking about a lot just one or two is all it takes to jam a pump?

Puzzled !!! any ideas or a similar experience welcomed.
