Bubba, sorry, don't own a Bijur, I've got the import clone just like you!
I'm wondering where that filter goes?
Is it just before the pump or just after?
If it is the latter, I'd be tempted to find myself an outboard filter and just put it inline between the one shot and your outgoing oil line. If you do that, there is likely a cheap and larger (more surface area) filter you could find that would be a long time clogging up.
Just an idea. All that Bijur stuff is darned expensive!
