EVIL ENERGY Fuel Filter Regulator 58 PSI fit for LS Swap EFI Conversion C5

Worked perfect for my Ls swap! Definitely recommend.

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.

Just what I needed

First one the locking tabs for outlet blew apart as soon as I went to put the fitting in, literally all 4 just broke and fell right into filter. Returned it got another one, once I fixed both outlet o rings and got them in their respective grooves the terminal for the ground strap on the filter housing snapped right off by breathing on it. Had to solder it back on myself to avoid sending another one back and getting a third. If it works once on the car the way it has been going it’ll probably catch fire. 😂

So darling very well.

it is what I ordered

Nice kit. Works well so far. Was easy to Install.

Easy to install, good product for the price. For my application I did have to get a different quick connect fitting.

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

no surprise

Quality seems to be good and was easy to set up and mount. Running the new lines was some work but all good

When I built my first LS engine, I bought a proper Wix brand filter/regulator. I needed another one for setting up junkyard engines on a stand to run them. This was a cheaper option. One of the fittings came damaged, but the seller was quick to offer a partial refund to make it right. The large single fitting would not accept the adapter initially. It would not lock in. I had to bend the little internal spring fingers to allow it snap in. It does indeed regulate right at 58 psi, so that was good. But you can tell the build quality is not as good as a Wix, or an OEM unit, so I do not know if I would use this on a beloved project vehicle. However, it does do what it is supposed to do for now.

Received the fuel filter kit to use for my tbss intake swap and the AN fitting are good quality, not so much for the corvette fuel filter that comes with it, the male fitting is loose inside the push connect send of the filter and the spring fingers don’t hold the fitting seated I managed to pop the fitting out with out using the tool. Very disappointed was hoping to complete my swap now it’s prolonged.
