Apart from length, is there any difference in the spec of the hose ? such as high pressure from the fuel pump ?
I do not have the plans with me at work but I think it goes something like this:
VA-136 = 23" X 3/8" (fire-sleeved) IO fuel hose from engine fuel pump to servo
VA-139 = 16.5" X 3/8" (fire-sleeved) from FW connection to engine fuel pump (or maybe from servo to spider)
Same hose. I'll can double check when I get home unless someone beats me to it.
