<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>

<P>It is not uncommon that a car´s service sheet also included the SU-pump
(clean the points every service), e.g. Lotus Eclat/Elite. However I never did
and I have had no problems. I used my car as a daily driver but it had to live
outside all year. Nowadays the car is pampered in a heated garage and is mainly
driven when the weather is suitable for open top driving except for long trips
abroad.<o:p></o:p></P>
<P>The pressure delivered by an SU-pump depends on where the pump is situated.
If it is fitted under the bonnet it should be a so called low-pressure or
suction pump delivering 1,8psi (e.g. some Austin-Healey Sprite/Mg Midget). You
can often recognise this pump by the 2BA screw (same size as the screws that
hold the coil housing to the pump body) on the coil housing for the earth spade.
If the pump is fitted near the petrol tank it should be a so-called pressure
pump delivering 2,7psi (e.g. MGB) or 3,8psi (Austin-Healey 3000, Jaguar 6-cyl.
cars MkII, E-type etc., Triumph Stag, Jensen-Healey a.o.). The high pressure
pumps can be recognised by a smaller 4BA screw for the earth spade. The pressure
is fixed and is controlled by the spring fitted under the diaphragm. All
pumps are identical as far as the coil housing, points system, diaphragm are
concerned. The differences are in the pump body but this has no effect on the
pressure, mainly on the variation of delivery pressure and flow rate. Some cars
have the h.p. pump fitted on the chassis open to the elements (e.g. MGB, A-H),
others have it protected in the boot (e.g. J-H).<o:p></o:p></P>
<P>There are three types of spring, the low pressure 1,8psi spring can be easily
recognised as the wire is rather thin and it has more coils, the 2,7 an3,8psi
springs have less coils and look identical to each other but the 3,8psi spring
is slightly thicker and should have a (faint) dab of red paint.<o:p></o:p></P>
<P>If the SU-pumps would have been so unreliable as some of you claim, they
would not have been used on such a large scale. Many millions of cars have had
them in the 1930´s through to the 1990´s, from the humble Morris Minor to Rolls
Royce.<o:p></o:p></P>
<P>Sure, the early ones did wear the points rather quickly because of
arcing/spark erosion, but this was counteracted by proper maintenance which was
usually every 1000 to 3000miles in the 30´s up to the 50´s. The wear was
significantly reduced by using a simple capacitor (very like the capacitor in
the points distributor), then a diode and lately Burlen fitting a transil. The
pumps are dual polarity except when a diode is fitted. <o:p></o:p></P>
<P>However spark erosion is not the main problem, that is electrolytic corrosion
due to lack of use and dampish conditions under the cover because of improper
ventilation like no tubes connected from the pump to a dry area of the car
(boot) or no rubber band or friction tape on the joint of the cover and coil
housing or damp storage.<o:p></o:p></P>
<P>I am not sure if the quality of the points you buy today is less than the old
ones. I have never used them. I still have NOS points to replace worn points,
but more often than once cleaning and repolishing the old points will
do.<o:p></o:p></P>

<BLOCKQUOTE style="MARGIN-BOTTOM: 5pt; MARGIN-TOP: 5pt">
<P>Not trying to reinvent the wheel, David, just get a fuel pump that
lasts. Others have had good service from points pumps like you, but I
haven't. I'm not doing anything unusual; if you get them installed and
they don't leak and they run that's about all you can do--there's no trick or
secret to installing them that I know of. Mine just keep failing, with
between a few hundred and up to 15K miles of service (this over about 140,000
miles I've put on my BJ8). I will say I have driven through some
serious downpours, so water entry into the switching compartment could be a
problem, but some of the failures didn't get drowned.<o:p></o:p></P>
<P>The points can be problematic, else SU wouldn't have gone
from:<o:p></o:p></P>
<P>1) no arc suppression<o:p></o:p></P>
<P>2) capacitor arc suppression<o:p></o:p></P>
<P>3) diode arc suppression<o:p></o:p></P>
<P>That is to say, SU wouldn't have gone to the expense and labor of
installing capacitors and diodes if there wasn't some issue with reliability
or longevity. I tried all three, with results as noted. I've
installed the out-of-the-box, rebuilt and adjusted them myself, installed SS
switching mechanism, used capacitors, diodes, TVSes, transistors and installed
SU electronic out-of-the box with predictable results. I do recall your
dad either writing or saying that they used to take the pumps out and service
them--cleaning the points and adjusting the mechanism I presume--at 15K mile
service when he worked at BMC (or was it BL, don't recall), so they aren't
typically bulletproof forever. <o:p></o:p></P>
<P>Maybe I pissed the SU gods off somehow; though both my sets of SU carbs
have been all but bulletproof, and the basic points-type in my BN2 has worked
for a few hundred miles.<o:p></o:p></P>
