Re: Oil pressure line through firewall
I just got thru with this but did not use the copper or plastic line covered with small vacumn hose for protection. I have never had a copper or plastic break in the 50+ years of rodding but I have heard of some as the newer copper tubing is just too cheap and thin.
I did use the hole thru the firewall grommet left of the accel pedal. For safety reasons, I just routed thru a newly made hole, above the speedometer cable (Z car here), I used a stainless wrapped hose with inverted flare end, installed a grommet around the hose then thru the fire wall hole I made, about 5/8" hole. I then used inverted flare fittings on both block and gauge. Now I know I will never pop a hot oil pressure line , in the interior, as long as I live.
As for the indention in the firewall, it was about at an 11 0'clock position, looking at the firewall from under the hood. Hope this helps.
You could also use the 1/8" compression BULKHEAD type fitting where the line does not pass thru the fire wall. I have seen this done very neatly. There are some photos on this site if you do a search on the subject.
Also notice in the AIM manual, page 30, show the interior cowl pad + where the oil line was suppose to go thru. No other markings that I can see. Also check page 9, you should see something that will give you some ideas. Hole #3 for the U17 option may be what you are looking for.
