You may also require some adapter fittings from your fuel sending unit / tank or fuel cell the manufacturer should be able to provide this information for required adapter fittings.

I used the ultimate fuel kit, very happy with the entire kit. I like that I didn’t have to coder the Walbro fuel pump electrical lines, it came with the connection. They answered my questions immediately, even on weekends. Definitely recommend!
