Thanks Larry, your comments are consistent with my thinking. I will forgo the primer
bulb and utilize the facet for priming and for duplicity. I do have the
check valve manifold at the carbs. Also, the facet is in the 3 to 5 PSI range
required for the Rotax 582. Keep those videos coming.
Thanks,
Dee

Glad to be of assistance. Keep in mind that if you use two fuel lines the
check valve is going to have to be in the other line, not where the two
lines converge into one.
Good luck
Larry

Just a quick comment by way of a question... don't both the fct pump and
the pulce pump have check valves built in? If so, isn't adding
additional check valves just installing more failure points? if they
don't have built in check valves then I suppose that they are
necessary.... next,,, If there is a failure in one of the pumps,, Will
it be necessary to shut that that line and pump off? I'm guessing that
the answer to this question is dependent on the type of failure. Or am I
just over thinking this?

I think the space program goes for triple or quadruple redundancy and the
computers take a vote! :-)
My thought is that a good ole squeeze bulb would be a good addition to
the dual electric fuel pumps.. Accessible from the cockpit... Over the
years I have met more than one fellow who did the "squeeze" to stay in the
air and get to a safe landing...! Obviously, the dual electric pumps need
dual batteries, dual generators and dual regulators.. :-) Herb
---------------------------------------------------------------------------
--------------------------------------------------
Of course one of those puppy's weigh a bit more than my engine will haul. I
find that in most instances if given half a chance it is easier to outsmart
yourself than not.
I know for sure that I have gone through about 5 of those squeeze bulbs and
had nothing but trouble from every one. Of course the problem with the
bulbs is the additives that are added to the fuel supply by the refineries.
For my own plane, I have one line from each tank with a filter on the
pickup tube, going to a selector valve, to a facet pump ( with over 600
hours on it) to an inline filter, to the pulse pump, then on to the carbs.
Sometime more is less, but that is a decision that each one of us has to
make.

The attached link has an excellent article on fuel delivery systems and
components. Heavenbound Aviation is where I purchased the check valve
manifold that=99s located near the carbs. This can be seen in one
of the photos. This article addressed all the subjects we=99ve
been discussing. Yes Boyd, check valves are needed within the pump to
allow a diaphragm-type pump system to function. Also, if one of the
pumps fail, it can simply be replaced. Thanks for the opinions all . .
. I=99m now confident that I=99ll not need (nor install) a
primer bulb.

and the pulce pump have check valves built in? If so, isn't adding
additional check valves just installing more failure points? if they
don't have built in check valves then I suppose that they are
necessary.... next,,, If there is a failure in one of the pumps,,
Will it be necessary to shut that that line and pump off? I'm
guessing that the answer to this question is dependent on the type of
failure. Or am I just over thinking this?

the check valve is going to have to be in the other line, not where the
two lines converge into one.

>> Thanks Larry, your comments are consistent with my thinking. I will
forgo the primer bulb and utilize the facet for priming and for
duplicity. I do have the check valve manifold at the carbs. Also, the
facet is in the 3 to 5 PSI range required for the Rotax 582. Keep those
videos coming.
