Hey Chris! Welcome to
I have an older version Ricks tank with a 5th gen pump. So far so good as long as I have a 1/4 tank or more (only on long roadcourse sweepers is an issue). That is with no baffling around the pump. So I can only offer what I've read/heard on the others
.
-I have heard good things about the Phantom stuff. Lynda Jacobs runs one that Randy Johnson installed in here '66 vert. She definitely drives here car hard. I know of a few others too with good results.
-the Tank's Inc stuff, I've heard mixed results. Seems like a lot of hot rodders use them, not sure how many are being tracked/autox'd.
-I've never talked to someone using the Caprice tank, only saw pics of it...I don't care how it looks like a big ole saggy diaper hanging under the car. I think to get it to fit, you have to cut a little bit of clearance.
Good call with the Corvette FR, lots of guys run that with great success.
