I have a Series I with a Mazda rotary engine in it. I use a Holley electric
fuel pump and it works great. The directions that came with it said to mount
the pump close to the fuel tank and below the level of the fuel tank. I
couldn't find anywhere to put it that would be below the level of the tank ,
but instead mounted it just in front of the tank. I made a little bracket
that bolts through the floor of the trunk just in front of the spare tire.
The idea is fuel should gravity feed into the pump to avoid excess strain on
the pump, but mine has been in for several years now (and driven daily) so
it doesn't seem to be any problem where I have mounted it. Make sure you
install a filter before the pump to keep particles that are sure to be in
your tank from tearing up the pump. Keep the regulator. I don't know what
pressure the Zenith or Stromberg carbs run at, but my Mazda carb takes about
4.5 psi fuel pressure. My pump puts out about 8 psi. I tried it without the
regulator, but the fuel pressure just over-runs the float valves in the
carb. The car will run, but only at full throttle! I use one of those dial
type regulators, but they will only handle pressure up to about 10psi. I
have my pump wired with 16 gauge wire and a 10 amp fuse. I have it on a
seperate fuse, but I also have a custom wiring setup due to the engine swap.
You might want to use an in-line fuse.
Good luck,
Scott Rohr
