Very strange Rusty, it should work unless you have a very low range Facet
pump or have some restriction in return line.
You *have* replicated my system because I also "T" the transfer pump
into the EFI return line to feed tank. It has no problem
transferring fuel with this arrangement. Facet makes these pumps in
several different pressure ranges. I think mine is the 4-6 psi
model. I used 3/8" line in this portion of system. Did
you use something smaller?
Yep, still
trying to figure out how to fix my fuel transfer
system.
What's it look like
now?
Remember the recent caution about copying a system
100%, or it becomes a new system? Well, guilty as charged. My
system is just like Tracy's, except that I only have one return line to
my feed tank. I plumbed the wimpy facet transfer pump into
the same line that returns from the regulator. That means the facet pump
is trying to push against the return flow from the regulator, and it's not
doing too well.
Even
at it's best, on the ground, with no other pumps on, the facet is slow.
In the air, fighting against one EFI pump's return flow, it takes a long long
time to see fuel moving. With both EFI pumps on, I almost wonder if fuel
isn't going backwards into the non-feed tank anytime the facet wasn't on
because the check ball isn't perfect. I added a one way valve to
stop this, and to stop the fuel from leveling itself between tanks when
parked.
The
obvious solution is to "simply" (NOT) add another hose to the feed
tank. Even if I go through all that hassle, I'm still stuck with the
slow rate of transfer of the facet. It's probably still the best
option, but I'm going to investigate every other option before doing
this.
