What are my options? Does anyone offer a conversion kit other than Supertec?
I'm going to run a 2.4 MFI engine for a while. I don't want to weld up an MFI hot air bung in my factory heat exchangers. |

You also need the RPM transducer to activate the idle position solenoid on the MFI pump

If you can just hook up the hose, that'll be easiest for sure.
If you want to replicate the Supertec style manual lever to replace the bellows on the MFI pump, it's not technically difficult, but would require a bit of engineering and fabrication. I'd think McMaster Carr or similar probably has a lever and cable mechanism, and you'd have to make a cover plate and cable mount to replace the warmup bellows on the MFI pump. |
