aeromotive a1000 pump, a13204 reg, -10 feed & return lines, -6 carb lines. just tapped into the bottom of the stock tank.
when it goes to "0", it means it's rich. the lower the number, the richer it is.
there could be a myriad of things causeing your lean condition. what does your regulator say? if it's still keeping enough pressure to the reg, then the problem is at the carb.

well, i have one of those Autometer with the cute little l.e.d. lights and at about 6000k it noses over and sputters. I have a Summit pump,supposed to max at 18 psi,3/8 line and Paxton boost referenced regulator set at 6.5 psi. The FP guage in car rises under boost but i dont watch it at redline.They put a PV in the secondary plate yesterday and it helped a little, but they swear my fuel system is too small, i suspect too, but i know people with less os system and their fine

im gonna check my rev limiter on the box. I ordered a new tank to sump it, and bid on a A1000 pump, then go from there

Thanks for the info.

I would be careful with a PV in the rear. It can get uncovered under acceleration.

i wonder why they would put one in then???? It was super rich, so they put a 3.5 PV and added the rear.

i don't see the point of adding a pv to the rear. it doesn't effect idle or cruise because the secondaries aren't open. for wot, you can just jet it down. it just doesn't make any sense.

I would agree with you because ever thing says if the pressure is up, the bowls have to be full. But it didn't work like that for me. I jetted up, and up, and up with the 650. Got richer and richer, but leaned out in the same spot everytime. I even saw as low as 10.2 I bought the A100 and problem solved, just like that. 350 bucks later, but problem solved. (when it leaned out, I was seeing 17psi.)

They told you to put in a PV in the rear because it can add more fuel to the main well. But like Brian said...It woks for a stock car or truck, but not cars that pull a G out of the hole, or 0-60 in under 3 seconds.

well as in your last post, mine was doing the same thing, as soon as it reached full boost about 6k rpm, it would go really lean.its not as bad now,and they swear its my my fuel lines/pump so i am going to copy your fuel system, already bid on a A1000 on Ebay
