Ford 5.0 OMC exhaust manifolds with O2 sensor?

[wilndadra]

I would love to convert my boat to fuel injection. Does anyone know if there are any risers out there that have a provision for an O2 sensor? I really like the FAST EZ EFI, but it needs an O2 sensor. TIA

or just go with a speed density efi setup and eliminate the need for an o2, just read barometric pressure via the map sensor..

Cool thanks Stackz!! I really like the brass fitting but i am not sure mine has a plug there. I will have to check when i get home. Thanks again!

I'm not sure but I think for those you drill/tap the manifold yourself.

if you look at the pics they have, it looks like they machined the surface flat before proceeding. cant think of any other reason to do that then you want a flat surface to drill into and seal against.

Thank you! I am in the process of converting a 351 OMC to fuel injection and was trying to figure out how to go about the o2 problem. Truth is I was going to just not have one.

windadra how you doing with your FI upgrade?
