<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.<br>
</p>
<p>The points can be problematic, else SU wouldn't have gone from:</p>
<p>1) no arc suppression</p>
<p>2) capacitor arc suppression</p>
<p>3) diode arc suppression</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. </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.<br>
