C5GTO,

I have the Aeromotive 340 in-tank unit in my 1981 Mercury Zephyr wagon. I went for the larger pump because it has a 557.

The wagon has more than 15K street and track miles without any hiccups. And I am familiar with EFI fuel problems caused by uncovering the pickup.

The 24 hour Rolex course at Daytona did not cause any problems during the four track days I ran there last year.

The Cobra is another, older, story. The Aeromotive setups were not around 15 years ago or it would have one also. Starvation occurred in that car even on an interstate when negotiating curves at legal speeds.

The answer to that one was to construct a "box" about 8" on a side below the floor of the tank, putting a piece of perforated aluminum at its top. The pickup is located near the bottom of the box. It was the result of an old drag racer's trick of putting the pickup at the bottom rear of the tank; this box kinda moved that idea to a 3-D version. The pump itself is external.

The "box" has been run 38K miles on the street and many, many track days including Sebring and Daytona among others and nary a burp.

HTH,

Tom
