So i went to both pumps feeding engine via a T fitting ensuring they alway have fuel to cool ,.....more than enough as no way it will ever need more draw than whats being pumped. Ideally probably this winter im going to install two small hydromats for each pump on both sides....its going to required dropping the tank and a lot of work.https://www.holley.com/products/fuel_systems/hydramat/
So instead of the passenger feeding the driver's side they both just feed up to the engine? 2 of the stock pumps would give you like a 500LPH+ rate. Definitely won't run out of fuel like that lol. Would you not still have the canister issue at low fuel levels though, or I guess each pump would only pull 1/2 as much and have twice as long to feed the engine...

I'm going to have to look into setting it up like that.
