REFLECTOR:Franklin fuel pumps

[Donald Royer]

I agree. The problem occurs only when parts made by PZL and old parts (or
engines) made by Franklin USA are mixed. If your engine is a PZL engine you
will have no problem with the new vane type pump unless for some unlikely
reason your engine has had some old parts installed.
That is not just my opinion, Pete Askeland of Franklin Engines told me the
same thing.
