Voltage regulator

[David A. Cooley]

Barry,
>From what I have seen of 3 different voltage boosters on the market, they
are simply a NiCad pack with some switching circuitry... under normal
conditions the NiCads are charging... under boost, they switch to being in
series with the battery feed to the fuel pump, adding the 3-4 volts
additional.  The big drawbacks are:
1. NiCads that don't get to totally discharge develop a memory... they only
discharge partially, so under extended demand they fail.
2. the life of the $150.00 fuel pump is shortened dramatically!

Best bet is look for a vehicle that uses a similar tank/pickup as yours but
with a higher volume pump and install it, or remove the in-tank pump,
extend the pickup line to the tank feed (put a hose where the pump was!)
and install a high volume aftermarket pump in line external to the tank...
About the same price as the booster, but infinitely more reliable!
