air in secondary filter

[asgard Lurker Find all posts View Profile Close asgard]

I have fitted a fuel master secondary fuel filter to my d4d but I noted it has a air lock between the glass bowel and the filter tried everything to get rid of the air but to no avail. have had a mechanic at it and he said it's not an issue, anybody else had this problem and did you get the air out (appears to run fine)
