Re: 1990+ Fuel Pump Theory Posted by Justin VanAbrahams [Email] (#32) [Profile/Gallery] (more from Justin VanAbrahams) on Wed, 16 Mar 2016 21:42:27 In Reply to: Re: 1990+ Fuel Pump Theory, Justin VanAbrahams [Profile/Gallery] , Wed, 16 Mar 2016 21:37:20 Members do not see ads below this line. - Help Keep This Site Online - Signup |
Whoa... is this a revelation or stupid?
Is it possible that return circuit is there to create a siphon effect through that vent to the tank? It just occurred to me the pump "bucket" doesn't have any major openings to let fuel from the tank in at all. That vent is - I think - the only way to get fuel from tank into the pump bucket. Does directing fuel from the pump outlet directly back into the bucket create a siphon that brings fresh fuel from the tank into the bucket?
