Saw this recommendation on a spam can list:
"GFlex 655:
http://www.westsystem.com/specialty-epoxies/gflex-655-thickened-epoxy-adhesive/
Great product, easy to work with. Ive been using it for most
everything that needs to be held together kayaks, boats, plane parts,
etc. The price for a quart at a time isnt too brutal. And you can add
pigment, glass powder, etc. to it.
If one can just get the basic shape taped together it will work."
Sounds like a useful product for us builders

Still chasing this fluctuation and engine stumble down. I started a proces

Is it common to have this much fuel stain in your FAB? Wondering if somethi

Blue stain is in the aft side of the filter and high up, which leads me to b
elieve this is happening in-flight.

The thing that has me wondering is if the new pressure level is too high. I know
that you can buy those pumps in higher pressure versions, which would imply
that they are also made in lower pressure versions. I'm wondering which one your
needs required. I watched my pressure today on a flight and it was generally
24-26psi. You said yours was over 30. I'm not sure how significant the difference
is, but if the pressure was higher, I can at least comprehend that perhaps
the additional pressure could cause fuel to be leaked out somewhere. Maybe
that's where the blue stain came from and it's all recent? Anyway, I'm sure
you'll get to the bottom of it. And when you do, it will be educational for
us all, so thank you very much for sharing.

I had some fuel there prior to the fuel pump swap. I know that because the drain
line had a blue tint.
The low pressure pump runs 4-6 psi for carbureted engines.
The model number on mine is the correct model number for the IO-540. I confirmed
it from multiple online sources (Tempest, Lycoming, etc.). Also confirmed
the correct model number stamped on the pump prior to installing.
Frustrating......
While I'm waiting on AFP to get back to me with some ideas, I bought some fittings
and a vacuum pump to draw a vacuum on various parts of the fuel system in
search for a leak.
I'd love to find a cracked flare or something like that and put this to bed.

Also confirmed in AFP documentation that inlet pressures of 20-90 psi are good.

perhaps the additional pressure could cause fuel to be leaked out somewhere.
Maybe that's where the blue stain came from and it's all recent? Anyway, I'm
sure you'll get to the bottom of it. And when you do, it will be educational for
us all, so thank you very much for sharing.

Interesting...well above Lycoming's spec for the Precision RSA fuel
injection unit...but that may be an area that APF "improved" over the
certified product. I agree you have the correct part number which is
used on most 4 and 6 cylinder fuel injected Lycomings. It is supposed to
have an internal valve of some sort to limit the max pressure by
bypassing some of the output back into the inlet.

I always have a fuel stain in the FAB. I think it comes from priming the engine
before starting and the excess fuel runs down the intake pipes into the FAB.
It leaves a blue stain there; never had in trouble from it.
