Great product. i would purchase this again!

Easy to use if you take your time and layout everything beforehand. For those who think these kits are pricey (like I did) I've bought others and you get what you pay for!

3.0

I have not fully installed this yet. So far so good.

Not fully installed, but lays out really well. Easy to read instructions. A fused fuel pump circuit would make this perfect. Not a big deal, but would not have to add a fuse to run a relay for the fuel pump.
