How many issues can you find?
A new RV friend who will remain anonymous contacted me with a problem. His newly purchased RV would quit whenever he turned off the electric fuel pump. A quick ground run verified that both the engine driven and electric fuel pumps were fine.
Before meeting him at the plane, I asked him if he knew how the fuel lines were routed. He didn’t but contacted the builder (who will remain nameless but this is supposed to be his 14th build) he was told the fuel lines were run “in the coolest part of the engine compartment”.
After pulling off the cowling, this is what we found. How many issues with this installation can you point out?
(The owner paid to have the fueling issues corrected and is happily enjoying his new toy.)

PS. Do not even think of asking who owns the plane or who built it.
PPS. The owner of this airplane granted permission to post the pictures when I took them and I agreed not to post them until his issues were resolved. He is watching and learning from your comments.

Does he know the lower intercylinder baffles are installed on the top of the engine, or did he do that on purpose?

Ouch! I gave up looking after seeing a hand full of issues. It certainly would have me auditing the rest of the build due to the builder's decision making process. It would make you wonder if you could trust any of his decisions.

That's 1.
Those pictures were exactly as I found the engine, upon removing the cowling.
The baffles have been removed and installed correctly.

Way too obvious Bob. Come on. There are two engine lifting rings. Nobody needs two engine lifting rings.
(wow, what a mess.....)

Safety wire missing on the injector spider screws.
Also, do I see the dipstick tube tyrapped to the motor mount with a rubber hose spacer?

I'll add a couple more that we noticed.
#5: The oil pressure sensor is tie wrapped to the engine mount and doesn't have a ground. So, the builder soldered a wire to the case. (You can't really see that from the pictures.)
#6: The "fuel line" (that's a hint) from the fuel pump to the fuel servo was undersized.
