Hi All,

   I didn't find as much as I'd hoped, but there was this:

 Subject:  [FlyRotary] Fram Oil Filter Pressures

 Greetings,

 I intended to use an HP1 racing filter, but thought it wouldn’t fit,
 so I picked up a shorter PH43 filter.   As it turns out, I was able to
 fit the larger filter by turning it about 45 degrees from vertical,
 but when I was considering the other filter, I asked Fram for the
 pressure rating.  Here’s their reply for both filters in case anyone
 is interested.

 Cheers,

 Rusty


 Fram’s reply:

 The PH43 has a burst pressure rating of 200 PSI.  The recommended
 operating pressure should not exceed 80 PSI.

 The HP1 has a burst pressure rating of 500 PSI.  The recommended
 operating pressure should not exceed 200 PSI.
