Does the Walbro pump have an internal check valve? If not and the pump is set higher than the pickup (which is probably the case for many of us) a check valve might be a good idea. Thoughts?

no clue on the walbro, but i used a mallory and i had to get a check valve from aeromotive for mine. other wise your priming the system every time you start it.
