Hi,
I have a MkII BT7, which is not particularly relevant here as it has an
AUF301 SU fuel pump which my manual says is from the "Later convertible
model MarkIII".
I have the pump in front of me as I type. It has a condenser (item 25 on
page DDD.13 if you've got the same hymn sheet as me).
So, when I take the car from positive to negative earth, what do I do to the
pump?
I've dug through my collated info on this topic and the collected wisdom is
a bit contradictory:-
1) Leave as is, but switch the leads around. Is that only for pumps
with diodes fitted instead of condensers?
2) Leave as is.
3) Replace condenser with a diode.
4) Replace condenser with Zener 20-28 volt diode.
5) Fit a diode, CSX1004, is what Burlen Fuels (the SU people in UK)
say. I suspect that they are just saying "Send money, NOW" but being polite.
Maybe a CZX1004 is a Zener???
What's to do here?
Thanks,
Simon.
