1 Fuel leak pressure regulator... Fri Dec 27, 2019 1:11 am

Hello!
Ive been doing a complete overhaul of my gas tank, did a test start tonight, everything that I had repaired and replaced inside the tank worked fine after a few moments of hesitation (engine has not run for a year)!
But... Behind the plenum chamber I saw a nasty fuel leak, in the first few minutes of engine running at idle, I saw a jet of fuel splashing (probably) out from the fuel return hose, close to the FPR.
I think the fule return hose is broken (and was the initial problem, not the indeed very poor condition of the parts inside the fuel tank) and I will replace both of the hoses to and from the FPR.
Would it make sense that the FPR at the beginning of engine startup will receive a fuel overpressure, and let it off through the fuel return hose? Or would it be more probable that the FPR itself could be broken or leaking?
Else everything looks and sounds ok, fuel return check valve is cleaned and is in good working order as far as I can determine.
If I replace the fuel hoses and the fuel leak is gone and engine is working ok, can I presume that the FPR is ok, or what do you think?
Thanx!
