Used for a TBSS intake swap onto a 5.3 LS stuffed into an s10. The price for the quality of the product is an absolute steal of a deal

Bought this for an ls swap, got it all hooked up and have been getting a system too lean code. Hooked up the gauge to find that this regulator is only outputting 46 psi, not 58 like stated. Went ahead and ordered the one I should have from summit. -edit the manufacturer reached out and refunded my order. I was just going to chalk it up as a loss, excellent customer service! Maybe I just received a defective unit which occasionally happens. Thanks for making things right, I will still order products from evil energy. Their fuel lines are unbeatable for the price.
