Thanks Harry,
I doubt if the pump is pumping more fuel than it should. On the times
I
had
to shut off the fuel supply to stop the over flow, when I turned it back
on
it
took around 30 minutes for it to fill up to the top and start over flowing
again. As mentioned, this only happened the first two times I flew it,
when
it
didn't have the plastic lexan tube over the wire gauge. I've now replaced
it
with a new complete new cap. After finishing the repair on my wing tank,
I
took
her up for two one hour flights. It didn't overflow either of these
times,
and
the header tank remained full. I suspect the new cap solved the problem.Larry [EMAIL PROTECTED] wrote: > Larry, > > I doubt you hurt the fuel pump....But, the problem lies with pumping more > fuel into the tank than the overflow line will take care of.//... > > The fuel pump should have a restrictor in the outlet side , restricting the > max flow to about 6 gal /hr...there is a proper restrictor filling for the > pump....; and the overflow line needs to be cleaned out.
