No, increasing the tank pressure did not help in my case. I have received
private responses that I should have thinned the primer, and I will try that
the next time I have a batch of parts ready.
BTW, thanks again to all those who responded by e-mail!

Bob,
I would be interested in knowing if increased pressure from the
tank end worked for that Alltrade HVLP top feed gun from Costco (I also have
purchased that gun but I have not tried to use it yet). Others have tried
the HVLP gun sold at Harbor Freight for priming parts also.
