Great kit ,very complete and relay has been working well. Can recommend. Jimmy, Making it work

### ⭐⭐⭐⭐⭐ Quality wiring & relay
*by C***R on October 5, 2024*

The wiring appears substantial enough, and the relay robust enough, to power the walbro 450 fuel pump without getting too warm like the previous setup did. The only thing not included in the kit that would be needed is dielectric grease and shrink wrap.
