Similar to the BP-4T kit, but with additional parts (fuel pump block-off, tank to Lock-off line with fittings, union to pass line through cover, hose splitters, barbed fittings). This is the kit you want if you're converting from gasoline and don't already have a regulator. All you should need is a tank bracket and you'll be set.
Remove that expensive and pesky Aisan regulator and replace it with reliable, readily available Impco style parts that will allow for cheaper replacement parts down the road. Also allows for conversion from gasoline to propane fuel system.
WARNING - PLEASE READ:
1. This is a universal kit. Expect to have to re-route hoses/cables, drill new holes, or re-locate brackets.
2. This kit will not work with trucks that have an electronic throttle body.
3. Installation should be performed by a trained and experienced technician.
4. Some small parts may be required to complete installation.
