[TR] Electric Fuel Pump (was Re: 2018 Kastner Cup)

[Geo Hahn]

Dave -

The pump says 2.5 - 4 psi.  I suspect it is on the low end of that range
(did not measure this one but have measured similar).  Have had no problem
with either the SUs or Stranglebergs.

As you probably know - it takes a pitifully small amount of pumping to
adequately supply those carbs.

One thing I have found with these pumps is that they cannot be installed
in-line (that is in the regular fuel delivery but not powered).  Fuel will
get through the idle pump but in hard driving (say 70+ mph or a fast
mountain climb) you can get starvation.  They could be installed in a
bypass mode I suppose, though I did not do that.
