But what if you’re converting an older carbureted engine to EFI, or want sequential injection on an engine with an early bank to bank EFI system? Sometimes, you may be able to get an easy bolt-on solution from…

The relay board has an onboard fuel pump relay that will work for smaller fuel pumps. The Walbro GSL392, for example, will work fine at normal fuel pressures. We used one like this on our Chevy Nova project. But if you’re running a bigger fuel pump like an A1000, we recommend avoiding running the current…
