Nitrous Express solves another problem! Installing a nitrous system on a late model EFI vehicle can be a hassle if you do not have one of the new NX high flow Fuel Taps. These high flow adaptors make the chore of tapping factory fuel systems safe and easy. No cutting or drilling just a quick, easy install that takes only minutes and each high flow adaptor has dual outlets for multiple uses. Works on 3/8 and 10mm fuel lines.
