Thanx all!
I'm reading these comments as if my life depends on it...
Can anyone recommend more reading material on the topic please?
Rich I see you mention: "if Tony Bingelis had devoted a full page in
"Firewall Forward""
Is that a book?
And is that good reading?

Adding a blast tube to direct fresh air onto the pumps helps.

HELPS?

ARRGH!

"HELPS" is not good enough.
In fact, going down the road of "helps"....
is a very dangerous and risky one.

A FIX is what is required.
Nothing less is acceptable.
Nothing less is defensible, IMO.

I have seen on the Great Plains Web site that they repeatedly
recommend
using a fuel pump.
They also recommend putting the fuel pump between the Gascolator and
the
Carb.
What happens if the fuel pump fails or loses power?
How much fuel pressure will the fuel pump add?
Won't the aditional fuel pressure possibly flood the carb?
How do I rig a return line to the fuel tank?
Why should a fuel pump be installed between the gascolator and carb?
Any Ideas?

Andre.........

An electric fuel pump shuts off when the fuel pressure rises to ~6
psig.
The
carb needle valve easily handles that much. If the fuel pump is
downstream
of the gascolator, the gascolator isn't pressurized. This reduces the
possibility of a gascolator failure which could dump your fuel in a
hurry.

It also means that the electric fuel pump is ahead of the firewall.
This
is
both good and bad. In the event of a fuel leak in the cockpit, the pump
won't be helping to fill the footwell with gas. The bad part is the
pump
is
exposed to engine heat. In the Sonerai, as in the RV's, I'd install the
electric pump at the tank outlet. Electric pumps push fuel much better
than
they pull it.

Just my opinion, tho.
