Off the subject of the sloshing compound, one needs to keep a very close eye
on a filter placed between the tank and the fuel pump. The filter in the tank
is quite course in comparison to modern day, high efficiency fuel filters and
do not clog often with the relative clean fuel available today. The in line
filter is a different story, it filter down to almost the submicron level and
can become clogged very easily. When they become clogged, they will cut off
flow to the fuel pump and cause it to stall in a current on condition. If the
power is left on to the pump while troubleshooting the problem it can easily
burn out th internal swampping resistor, removing what little arc suppression
is available on the early low pressure or high pressure (in the case of TFs).
The final result is points that burn prematurely with replacement points alos
burning much quicker than they should. If this should happen to one of
today's all electronic fuel pump that Burlen Fuel Systems has made available,
a burned out swamping resistor will stop the pump altogether.
Cheers,
Dave
