Wouldn't one want a pressure regulator somewhere between the fuel pump
and the carb? Maybe the carbs you're referring to have one built in to
them, such as a float

Please take note; this IS GOOD INFO FOR ALL FUEL PUMPS ELECTRIC! Typically
they are COOLED by the fuel that passes through them while they are running.
I have seen countless bulletins sent to auto technicians warning running
tanks dry during trouble
Phillip asked about fuel pumps running from crankcase pulsations.
I am flying a Renegade with a Rotax 582 two-cycle engine. It has a pulse
powered fuel pump mounted on the firewall. That engine burns 5 1/2 gallons per
hour at cruise, so the output of the pump would be more than adequate for a
Netters,
ON auto applications where there is multi-point fuel injection the fuel IS
constantly re-circulated back to the tank, through a return line that is BELOW
the fuel pickup for the fuel pump. The pump is only immersed in fuel completely
at high levels and is cooled by gas flowing through i
With all the problems with these things it is hard not to believe we are trying
to reinvent the wheel again. Motorcyle carbs like the mikuni and zenith are
intended for gravity feed but some bike designs with their gas tank shapes do
not feed well that way. So some have small electric fuel pum

Hi, I just thought someone might benefit from this-
The fuel pump used on 1000cc and 1100cc Yamaha Virago
motorcycles might be just what you need on a system
with float bowl carbs. They are one piece, self
contained with a pressure sensing diaphragm built in.
When the pressure required by the carb
For those needing to control the pressure of fuel pumps to
a low pressure carb check out the fuel pressure regulator
at Auto Zone. $20 and is adjustable from 1/2 to 5 1/2 pounds
approx. I have one on my KR and I believe it is the same
type used by Marty Roberts. My hangar neighbor has
a Zenair
I used a similar device and found that at wide open throttle the fuel flow was
not suffient and caused a lean condition at the highest rpm

Larry,
DO you have a part number or SKU.
At AutoZone, they can't do anything without a vehicle
application, SKU or Part Number.
