Fuel volume drop after regulator?

It seems more attention to mounting and plumbing is what is needed. Just my opinion. Like belly buttons ..... everybody got one!

The old holleys were it years ago. I remember having to put the big springs, big line, 2 pumps mandatory and that was with a Holley carb! It seemed like you had to take them apart and clean them thoroughly each season at a minimum. The regulators were something you cussed at and hit with a screwdriver handle more than adjusted! LOL.

I drove a SSAS in early 80s. We always did the burnout with one pump on then turned the other one on to stage. Dumb me forgot one. I made it part way through low gear before it about quit running!

There are some real good fuel systems out there that just weren't around back in the day. Mounting and all that has to be good, but the fast Q jet cars typically have well prepared systems that might look like overkill and maybe are just enough.

This doesn't mean that a car can't run with a Q jet and a Big Block with a holley blue, etc. , but when you are racing stock, the usually calculations don't always apply. You have to give the car what it wants, even if it is different than every body else's.

We run a magnafuel pump and a product engineering Qjet bypass regulator and am very happy with it. Just a 327 stocker Stickshift combo in E/Stick. I would not go smaller than what we have, even if it seems like it is too much to the casual observer. It doesn't flood, I can tune it, it doesn't flat out. The pump has proven to be very reliable too.
