Box stock clone fuel pump- where is the vacuum source?
 

I'm building a harbor frieght 6.5hp clone moor. I have a walpro fuel pump, where is the vacuum source? Thx JR

vacuum is sourced at the intake manifold, between the head and carb. you may have to drill and fit a hose nipple into the intake

Thanks! I put in a 1/4 npt hose barb- should be firing it up in a week or so.

Ya they don't come with one from the factory that I can think of. Were you able to easliy drill and tap for a nipple?
