Is there such a thing as...
...a "self-contained" injection unit? I'm about to re-do my engine and was admiring the marine TPI injection units...all the electronics are contained on top of the motor, no return lines to hassle with, etc., etc.
Do they make something similar for an automobile? Would a marine unit work on a car?

I want to install an injection unit without having to run wiring harnesses, controllers, return lines, etc. all over the place.
Here's a unit I found on E-Stink:

The marine ECM's are pretty basic in that they don't use O2 sensors. I think they are speed/density units that use a table for fuel ratio. That table may be difficult to edit depending on the ECU they use. I used to look at the offshore boating forums (www.offshoreonly.com) for info on BB EFI. They are doing very impressive things with marine engines. Nothing is more punishing to an engine than to rum at WOT for an hour at a time.
The fuel injection pumps that are used are usually a self contained unit that includes a reservoir, pump, return line w/float shutoff all in one unit. I have a Mercury Marine pump like this but I cant figure out where to put it in my car (because of its size).

The bad news is that they are difficult to mount in the car, they need to be mounted in a place where they could not be hit in an accident and dump a bunch of gas and they are expensive to rebuild. Most of the offshore boat seem to be running Aeromotive and Holleys.
Yep...that could pose a problem. My boat is carbureted, so I haven't had the opportunity to look at a Mercruiser EFI close-up.

It looks like you can get a full setup for around $2500 with their discount for the Victor Jr. manifolds.
