Ok this is easy for most people but me. I installed new fuel line from my tank to the front of the engine but i cut out the old stuff last year and not 100% sure if my flow goes on the left or right. Keep in mind its a old grumman step van, also i was not getting any fuel to squirt out of shrader valve when i stuck a nail in it, thats why i thought maybe its backwards.
please help bring the heap back to life
