I have a 85 12a rx I know the oil injection lines are important where is it possible to put them on a Holley directly in it or is there a better way ?

If that is a real racing beat carb,there will be a hose barb on the one of the float bowls or metering blocks,can't remember which one off hand

The way we used to do is, you fab up some longer lines. Remove the Carb. Drill 2 1/4 holes near the butterfly and feed the carb oil through there. And to manipulate the hard-plastic hose, just use a lighter and bend to shape. Hold down with some Plastic Ties and you're all set.

yes it's a RB carb, 465cfm for the stock port 12a.

the RB holley uses a barb fitting threaded into the site plug hole of the primary bowl. i used a vac fitting in the shape of an "F" at the omp to make the 2 lines into 1. then connect that one line to the barb fitting in the primary bowl.

Here's what I ended up doing. Drilled 2 1/4 inch holes near the back of the butterfly. Doing that made me keep the original length of the plastic oil lines, drilled two 1/4 inch holes at the bottom of the racing beat air cleaner then reinstalled the original lines through their.

^so where do u have the hose off that nipple in the fuel bowl going to?

It's connected to the fuel return line is that wrong ? The brass fitting is connected to vacuum advanced
