Re: Fuel supply questions

Using 3/8" lines has fared well for many of us. Also, minimizing the number
of fittings used will minimize the fuel's resistance to flow.

I think the MA3-SPA carb has an inlet pressure limitation of something like
6 PSI, so be careful with your mechanical pump. IMHO, lighten and simplicate
by ditching the mechanical pump. Then you'll get to save 50 bucks, too.

Thanks Sam . That is good news. Would that be a 5/16"feed or will 1/4" do
the job?
Jab are running a mech pump and an electric pump in series. Bad idea it
doubles the risk of a blockage by jammed valves and would cut off gravity
feed.
I was planning to keep the mech pump but run a gravity feed direct to the
carb with the pump in parallel. But would need a stop valve to prevent fuel
recirculating.
The Spruce listed Andair stop valve looks good but $50 seems a lot to pay?

The answer to question #1: Absolutely.

#2. Depends on what you mean by "cheap" and "OK".

Hi, can anyone advise on two fuel supply questions:
1. Is gravity feed enough to run the 0-200 with no fuel pump?
2. What is a cheap but OK fuel check valve. Spruce list the Andair
rabge
for about $50. Are there any OK alternatives?
Thanks,
Peter
