How does the engine look?
  Do you have any guesses on why did it caught fire?

  No question at all about why it caught fire -- those damn plastic ends on
  the MSD fuel pumps snapped off & fuel was being hosed into the cowling
  post
  crash.  The hottest part of the fire was right at the fuel pumps.
  Terry was
  trying to go around when he lost it - thus both pumps were on and
  running at
  impact.

  I really think those MSD fuel pumps should not be used by anyone
  because of
  the plastic elements.  As you'll remember, I dropped one & the plastic
  shattered on that one too.

  Rotor 1 is shot.  The p-port got torn loose and shoved into the rotor
  chamber while the engine was still turning.  I expect to find the apex
  seals
  shattered & the chamber shot.

  I cant get the damn e-shaft nut off so it will b a while before I get
  around
  to tearing it down.

  I don't know why we have to crash to find out stuff like this fuel pump.
  I was advocating these things until this happened. I sent a copy of this
  email to MSD.

  This P-port was one of our early epoxy bonded in versions. That was the
  first and last one done like that. New ones are stainless steel welded
  in.
  It will take a direct axial heavy impact to shove one of those into the
  rotor housing.

  Here's an all metal alternative

  I don't think that is high pressure EFI. I think that is
  throttle body injection at 15 psi.

  What you are looking for is a true roller vane pump that will lift
  a head of fuel. Important for low wing airplanes.

 The Bosch Cis efi fuel pumps are all steel with threaded bosses for the
 fuel lines. They are well tested millions made. Some even have a check
 valve in the outlet. Roller vane.
    Very high quality. I mentioned this on this web site many years ago.
 No one paid any attention.

You guys really should be using the pump recommended by the maker of the
injection system (Tracy Crook) - the Walbro 394 or equavelent.  They are
inexpensive, all metal, have threaded fittings for any type of adapter, have
a built-in spring loaded check valve, and weigh only a pound.  They have
worked well for me for 500 hrs.  It turns out that they also made the
perfect solution for a pump for my smoke system.  So my plane flies with 3
of them.

Available via many suppliers, here is an example:

I got my pumps from Tracy, and they wer the MSD plastic pumps.

As far as I can tell the old Walbro are gone.
There are other roller vane pumps on the market.
