Engine failure

Some are. So I have to ask.

Anyhow, if so it may be linked to a problem in the fuel pump. Mine was
actually missing a connecting spring (from factory) that did not allow
it to maintain a fuel flow at idle settings. So for years I go around
with it a bit high on the idle and sometimes on rollout, just at the end
and starting to turn off, the engine would shake and I would hit the
electric pump to bring it back. I actually had it down to a fine art.
The problem was only found when the pump was pulled and sent out to have
a seal changed.

Without me having to go to the TCs and do a search, can somebody please tell
me what series of 172s were injected?

And again the models of 172s that have fuel pumps?

All of the 172's at my FBO are FI, but they are all 1999 and newer.
Probably doesn't answer your question too well. Always gets me when I
go to pull on carb heat during a descent and it's not there.

I think it's any of the "new" ones - 1996 and newer R and S models.

1996 and newer - R and S models have electric fuel pumps, certain
serial numbers of which also have a SB out against it for something to
do with a diaphragm issue and inspection thereof if memory serves.

Hawk XP is injected but it has a 195 hp Continental 10-360-K in it.

The newer 172's are fuel injected. They will have an engine driven fuel
pump and and electric one.

A lot of 0-300's in the older 172's have fuel pumps, I am not too sure why
though. Maybe because of the 6 cylinders?
