I re-read the whole thread and I was wondering if you tried to blow air from the pump to the engine bay? The line from front to back is mostly metal with rubber hoses on each end, so maybe there is an internally collapsed rubber hose in the loop? Seems unlikely the metal line would be a problem since it runs inside the car and is unlikely to get crushed. The engine supply line runs along the driver side sill under the carpet and feeds the cold start valve and injectors. The fuel flows through the injectors, is regulated by the FPR and excess fuel goes back to the tank via the return line. The return line goes underneath the engine, then back to the tank on the passenger side. I'd imagine both supply and return have to be without obstruction for fuel to flow. It may be a good time to replumb all the rubber hose in the system, so make sure you buy some that can handle at least 30psi of pressure.

Looks like amazon sells 25' of 1/4" hose that can handle 50psi for $22, but that may be a lot more hose than you need.
