L31swap fuel regulator
Hello fellow c4 owners. I’m buttoning up the final bits on my first engine swap and I’m having trouble finding good info on fuel regulators. I have a cammed L31 with ported 062 heads and 30lbs injectors. I plan to get a tune and adjustable fuel regulator. However sense this is my first swap I’m in pretty unknown territory right now. I’ve looked on forms here and it seems like the BBK regulators won’t clear the stock TPIS. I found a holly regulator for $200 but is that the best yall have found? Hoping for some direction and advise. Thanks yall!

I'm not 100% sure it would fit, but take a look at the Aeromotive compact regulator. I'm using part# 13136 on my LS swapped 84. I don't have any complaints about it. It's ethanol compatible and is really small. It also can support up to 1000hp.
