[Syty] Fuel Pump

[bullyhart at aol.com]

I was getting about 10 volts at my pump, with the stock wiring and 90,000 miles.  I made my own relay system to get proper voltage to my fuel pump.  The Racetronix harness is nice and easy to install, but I chose to do my own relay setup.  Either way, I also recommend going with a quality relay to power the pump when replacing it.

Part of the voltage supply problem at the pump is that
# of junctions/switches the power has to go through
before reaching the terminals at the pump. Look at any
SyTy schematic. There is a major voltage drop through
the park/neutral safety switch, the Oil pressure
switch and the ignition cylinder.
A common fix is to not rely on the marginal stock
wiring and use it only to trigger a relay supplying
fresh juice right off the alternator. This helps
insure you get whats at your alternator is AT the
pump. not -3V.

Best of luck getting it swapped, and go for the
Walbro.
It is designed to outperform the undersized stock pump
in every aspect.
