The other day I received a few parts that I ordered recently. Included in that ground was the air/oil separator, plus some fittings and hose from Earl's performance. I came up with a solution to replace the breather hose supplied by Vans and the problem of routing the hose around the 90* oil filter adapter. I didn't want to use a plain 90* NPT fitting like the one that came on my engine. Not that there is anything wrong with the fitting, but to remove or install the fitting, the engine has to be removed from the mount (a big PITA).
From Earl's perfomance I ordered and aeroquip -12NPT to 3/4" barb 90* (full-flow) push-on hose fitting. I also ordered a 1/2" NPT to -12AN straight adapter. Earl's also sells hose for push-on fittings in large sizes so that is compatable with engine oil and combustion gasses.
I mounted the air/oil separator to the firewall backed up with a doubler to spread the load. I instlled the adapter fitting in the engine and then connected the separator to the engine with 3/4" hose and the aeroquip fitting. I still need to fine-tune the clock position of the separator and trim the hose a bit (can't forget to add the clamps). I think this solution will work out pretty good. The fittings weren't all that expensive, less than $25 for both and the hose was $6 a foot.
I ended up using a straight fitting at the oil return rather than a 90* to keep the hose clear of the battery box. If I change the clock position of the separator I might be able to change fittings.
