For testing you could make a tank from PVC piping. It will handle the
pressure if any and also the temperature. You could also install a simple
oil filter in line.
I know you will find the tank... Of course it will be in the last place you
look. ;-)

Guys -
I don't know how it happened, but my Veteran's Day message became attached
to an email.
I can only blame it on Google.
Go figure, yet the words are still true.
