The “overview” info, as well as the picture, say it can be mounted near the tank

Like it shows in figure 2B on page 2 with the regulator near but after the throttle body. https://documents.holley.com/199r10575rev3.pdf


The regulator you have is the same in operation as a Corvette filter/regulator and works fine in stockish applications. When you go from needing not much fuel to a large amount of fuel it just doesn't react fast enough and it is too far away.

Well its currently set up like 2a... the regulator is just back near the tank/pump.

I don't see a way to do 2b.... that's going to require a fuel log and the return coming off near the front of the carb/TB and then looping and going back.....going to be really hard to do that, both mounting any regulator and plumbing
