Thanks for the ideas! I got back with no issues at all, not a drop of diesel out.
Before the trip I cut off a mini-section of the above mentioned hoses, the `standard heater hose` (currently being used) + the thick wall heavy duty heater hose + the pneumatic hose as well and soaked them separately in #2 Diesel just to see if anything happens... but so far (in about 5 days) there`s no breaking down or discolored fuel visible in the jars.

Also, this allowed (necessitated?) the use of larger hose clamps, which are easier to create a good seal.

That`s a good thing to keep in mind! Mine got so dark (brown) there that I can`t see a thing going through. I`d like to replace it. A troublemaker air bubble might be still visible (& would be a bad thing to see there anyways... ) so for now I`ll stay away from tinkering around the injection pump.

What is the quality of the heater hose? My guess would be at least a few weeks. The hose will start to "sweat" long before it starts dripping good.

I don`t know about the quality of the hose. At least my blood pressure went down as I saw the jars with the experiment specimens.
I don`t have much curiosity of how long they withstand being immersed in (bio)diesel so I`ll get that hose super-junction replaced with the suggested quality of fuel hose, cut to proper length, in one piece.

Do you have a fuel pump at the tank?

I think I do have some help for the IP; having the fuel system pressurized by a leftover pump from the 4cyl setup, but I`m not quite sure yet. (Probably the `Red wagon build` thread mentions it?)
After disconnecting the hoses I left both ends open so I basically let it lose a few liters of fuel but later had no issues of air entering; I turned bleeder screw on filter, also kept idling for a while.

I also found a nice informative website to buy any type of hoses. I love it because you don`t have to get a minimum of 25, 50, 100 feet.
