SLY To add to Clyde's post that vapour line can be used as a return line but I would alter it inside the tank! In the as-is state it could cause a lot of aeration as the baffle in there would cause the returning fuel to fall in a spray and drag air in with it. I would remove the little baffle (a small "C" shaped cover and add a tube to reach down to near the bottom of the tank and preferably away from the pick-up) I know it sounds easy and it will offer some challenge as space and routing without interference to the sender and the pump (we know you are using a mechanical one [still?] is tight) Did you remove the electric one or are you going to stage them in series? I am not sure if you will need a vented cap or not as the factory set-up is vented with the vapour canister set-up that Clyde had mentioned. Let us know if you find a vented cap that fits our cars as I am sure a few of the team will want/need this info sooner or later, therefore I would GUESS that a vented one will be necessary, if the canister line is blocked off at the rear and I wouldn't leave it open in the engine compartment myself! If you block off the line with a vacuum cap make sure you use a clamp on it, or better yet mechanically cap/remove it (weld/braze etc. off the tank of course) Harry
