<p>Are the factory settings per SU the same as those in the shop
manual (Bentley, in my case)?</p>

<div>We install and sell probably about 50 to 75 SU fuel pump
a year with almost 0 returns. The only time when we had an
issue with the SU pumps is when they first came out with the
Positive Ground pumps.</div>
<div> </div>
<div>The reason for this is they went backwards in time about
50 years.</div>
<div> </div>
<div>Originally the pumps only had a set of points and no
condensor. Then they installed a condensor in the early 50s
to solve the pitting points and sticking problems they were
having. These pumps were used thru the early 80’s with very
few issues other than failures due to age. Sometime in the
late 80’s or early 90’s there was a demand for originallity
for a Positive Ground pump at the time the had changed from
a condensor to a diode in across the points. So the answer
to a Positive Ground pump was to remove the diode. This
returned the pump the original design and they started
having pump failures in the Positive ground pumps.</div>
<div> </div>
<div>Then somewhere in the late 90’s they started installing a
non polarity concious diode in all the pumps. Thus solving
the problem with pump failure due to the points. </div>
<div> </div>
<div>The one issue that we did find with the pumps in the late
90’s up until about 2005 was that the diaphgrams / points
adjustments were incorrect. So we would always pull all of
our pumps apart and re adjust the points to the factory
settings as per SU.</div>
