Converting non fuel injected 72 type 4 to fuel injection

[spaine]

I am looking for some guidance on this topic and am not finding much through searching.

I have a 72 type 4 buss and would like to go with fuel injection. I am looking at some complete kits off of 78 busses but I know there is a displacement difference. I also know that I will need to figure in a fuel return line to the tank. Otherwise, will it work? will I have to go with smaller injectors? Any other concerns?

Thank you.

It will work fine but you should adjust the AFR once you are done installing it. Locate the aircleaner stand off a junk bus and weld it in to hold the AFM/aircleaner securely in place.

Glad to hear this is doable. I'm going to move forward with this once I have sourced all of the components.

In another thread, I saw that someone had found what looked like a reproduction of the AFM stand. I am looking around for this but not finding it yet. Has anyone seen one of these available? I do not have access to junked busses in my area to pull one from.

You will also need to cut out the rectangular slot that the ECU anchors into.

Wasted Youth: Thanks, I'll see if I can find some pictures to detail what I need to cut. And as a side note, I spent many a years in Clovis - loved that valley oven fresh air!

Rustbus did a similar conversion and had this picture which shows the ECU cut out:

And it is this shot that shows the aircleaner bracket that I am looking for. I PM'ed Rustbus to see where he got it:

That's cool! I would like to do the same thing to my 1973 bus. I was very happy with the performance of my 1977 bus when I had it.

Yeah... great air quality!

I trust you already have the Temp Sensor II figured out?

[Bleyseng]

Temp 2 sensor is easy as you just drill and tap the tin hole on #3 cylinder like stock.

I'm adding FI to my '73.

That project is alongside working on rust in the window channels, but my comments start on page 3 of my build thread.
