New regulator Hey guys, I fitted a new regulator, a aeromotive regulator x1 bypass regulator, the older aeromotive i had, had a -6an return port, so wanted to upgrade to a -8an return port, so fuel doesnt get overheated etc
since fitting new regulator, when on boost, the old one would boost ref 1;1 perfectly, 15 psi of boost and i get 15psi more fuel pressure, so the new one, doesnt seem to want to go any higher than 54psi, even tho iam at 15psi of boost, i know new regulator also had a higher fuel through put compared to the older version, my fuel pump is the same, it flows enough fuel for 1500bhp boosted hp
thoughts anyone?

Id send it back... It's not working as it should. I've had surprising luck with the MSD 1/2" return regulators. Ran 4 of them now and I've never had an issue. My 4303 defiantly heats up the fuel still. If I have around 2 gal or less my fuel and pump and fuel get damn hot. I make it a point to stay mostly full. I was also told to run a -12 return from aeromotive... That company's advice and prices VS performance are ridiculous. If I had listened to them I'd have $3k worth of fuel system.
I agree with the above, stay away from them.

As always...most of the heat comes from the hot fuel rails, not the pump. And it's daft to say the return line causes it lol
I'm sure it does. Was only stating that regardless of my -8 return, it still got hot. And without very much in the tank it gets continually hotter.

Are you deadhead plumbed or do you have the rails Y connected in with the regulator after the rails? Because if you are deadhead now the first thing I would do is go to a Y plumbing to get rid of hot fuel. Keeps the fuel moving past the rails all the time.
