For the OBS Walbro fuel system, check out these videos. This first video is kind of outdated when describing the kit and you do NOT cut the rear of head lines. However everything else in this video is on point. As of right now, our website is 100% up to date. The bags you receive should be the same as what you see online. With the exception of 4 additional parts they now send in 2 bags. 1: front of head fittings and 2: extra's.
Here is a more updated OVERVIEW video of one of our kits installed.
Next, you should watch this video. It goes into detail on our fuel pump replacement fitting.
Here is the updated extra's bag they send out that include new "sleeves" for the factory rear of head lines.
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"
Marty's has 2 different fuel regulator setups. Both can be viewed here. The 3rd and most preferred mounting is in the 2nd video above, labelled overview.
Next you should watch this video to understand our wiring harness.
And last but not least, they have a key on power source under the hood option for your wiring harness.
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.
