Walbro fuel pumps hold pressure/check valve?
anyone know if the Walbro fuel pumps hold pressure after being primed?
do the Walbro pumps have a internal check valve?

Yes they have a check valve, mine does bleed off after awhile But I am not sure if its the check valve leaking back or the malpassi regulator that has a bleed in it..

My cosmo fuel pump doesnt hold pressure, is this normal? Should I run a check valve to keep the lines primed?
