I have air
leaks on my Ford
Lehman 120 so I am pulling everything apart and re-doing it. On paper it's fairly normal: Tank-algae X-Carter
electric pump-valve-Racor 900-valve-lift pump-CAV filters-injector
pump. The hoses were run very poorly startin well above the tank drooping well below it with poor spliced hoses for the return lines etc.
The
fuel in the
Racor looks great but when I pulled the CAV filters off there was
water and some trash. I am not sure how it got past the
Racor? is the 900 just to big? I read somewhere the turbine effect will not
work with this low a circulation 1.7 gph
I am thinking about removing the Algea X and the 2 valves(filter is 3-4' above the tank) I am thinking of ways to make the system simpler KISS, So I have a few questions:
Why wouldn't a 2 micron Racor 900
work without the CAV filters?eliminating them all together.
Why not eliminate the mechanical
lift pump? when the
diaphragm fails won't the
electric pump fill the
oil pan up with
diesel when you're trying to get home? A spare
electric pump would be easy to carry and replace.
What about replacing the CAV filters with one Raco 200R or similar filter?
I would like to simplify the whole thing of course I can just put it back the way it was. I hope I found the air leak, a oring was missing from the bolt that goes through the CAV filter.
Proposed setup Tank-Racor 900-electric pump-injector pump
or as above except with a Racor 200R after the
electric pump.
