Thread: think my walbro 255 went out. suggestions?

anyone else get aggravated at the fact that they dont keep full pressure in the fuel system, not sure if its a walbro thing or what, but everything is tight from the fuel pump to the fuel rail and everything, new o rings, and everything, still has to build pressure on start up if i leave the car sitting for a while. maybe becuase they dont have a check valve or something, it just aggravates me personally

I think there is a check valve somewhere in between the engine bay and the tank that goes bad sometimes.

I do this. I put a small bit of rtv where i cut it just to make sure it seals.
