Howdy folks. I know there are a few references out there on where to start with this one, i.e. TDIFAQ, and elsewhere.
I am going thrru them and trying to understand more about this problem. Most references say that a few tiny bubbles is normal. These bubbles are pretty big if you ask me and they seem to come in waves. I think I have found one potential cause for air leaking into the system. My question is twofold.
1) The filter is new i.e. <3000 miles. Just performed the water separator maintenance, no water at all. When I bought the car the PO had an in-line filter set up that had no water separator. I immediately changed it out for the factory specified filter, but I was not sucking air until I went back to the original factory setup. Why is this? I am happy to change the filter out, if folks still think this could be the issue.
2) What fuel line material should I use between the tank feed and the filter and how long should this hose be? I think the black rubber line the PO's mechanic used is too short here as it does not even go past the barb on the black feed hose from the tank. It is about an inch or two short of the barb. Would this be a likely cause/location for a leak?
Thanks!
p.s. I think this could resolve my DTC 01268 issue as well
