After that you should watch this video that explains all the different front of head assemblies for our OBS kit. All kits now include fittings that go into the heads that require all of the teardown of the original video. 4x6 adapters to locate your regulator outside of the valley. Different 4x6 adapters to locate your regulator in the valley directly off your factory lines (preferred, easiest install.)

Here are the adapters you can use in place of the "front of head fittings"

If you experience an issue with your fuel system, please follow these 2 diagnostic videos before you call in. Make sure you check the power and ground at the pump and run this system on it’s own fuel supply. More than 80% of "fuel pump problems" are pre-pump issues.

    Disappointing
    Color: Black/Black/Black
    Overall the watch is ok. The price doesn't reflect the quality of the watch. This should be a $20.00 dollar watch. I purchased this partially because I thought the number would glow at night, they do not. The hour and minute hand barely glow at night. I decided to just keep it, rather than returning it, and now I wish I had just returned it. After 2 months, I got a scratch on the watch, what looks like cheap, plastic. I can't say I would recommend it for that reason, I'm a average field watch wearer, which means they have to be somewhat durable. This was disappointing.

    Great watch to have
    My husband has used this same watch for YEARS. He loves the basicness of it. It may not be the EXACT one, but pretty darn close. He loves the timex brand. He wears it everyday and is pretty hard on things. The only reason he needs to get a new one is because the bands break. For the money its a great deal.

    Timex quality and reliability 👍🏼👍🏼
    A really nice watch with a face big enough to easily see the numbers. One thing I like is the watch band is more comfortable than usual ones. Recommended
