I have an '84 GTI that has been modified for Auto X SMF which has a fuel starvation problem on high speed corners when there is less than a 1/4 of a tank. I had the tank replaced when the car was restored but I didn't use a stock tank VW part. Did VW have a baffle? What do you recommend...Holley makes a fuel supply part https://www.holley.com/products/fuel_systems/hydramat/hydramats/. Somewhat expensive. IS there a baffle?
