Size of fuel hose for Perkins 4-236
One of my springtime projects is going to be to replace the fuel hoses on the twin Perkins 4-236's of the Gulfstar. They look a little dry and cracked, and I am sure that the port engine overheating that time was not good for the hose.
I would like to go ahead and order sufficient hose length online before starting anything, but am not certain about the fuel hose size for that engine. Does anyone happen to know? The ID, primarily.
Thanks for any help.
