Sorry for not responding earlier but been off line for the last week.
Adam...I did not block off the stock breather. Intake is at front of case and exhaust is from top of valve cover. Performance wise I think it pulls harder in mid and high range,and oil stays cleaner longer. The yellowish color of new oil stays yellow longer, doesn't darken as quickly. Don't know if that translates to cleaner.
The gauge I used was a Stainless Steel-Case Liquid-Filled from McMaster-Carr. McMaster-Carr Type in 3850K3 in the search. Quite happy with it so far, about 3,000 miles. I have a SRM oil pump installed, hot idle is 14-20 and 60 at high revs. The liquid-filled is the way to go, needle is rock solid.
Leon...You are correct,tried to isolate vibration with rubber grommets .
I have a 1970 A65 with an oil pressure gauge and want to replace the hose. Do you know if this is the actual fitting required? For the purposes of comparison, or if I go to McMaster Carr instead, can you let me know what internal diameter and fittings are correct for this application? I have a Sunpro gauge.
PM sent to Eddie: For the rest of you, those line kits include 1/8" NPT fittings for the case and the gauge. The hose is 4AN, pretty much brake line. The kits are available from Summit, Pegasus, and on eBay. Search for Quickcar brand.
Thanks again David. FYI measuring mine, 36" will be fine. My OP gauge is mounted to the left of my (central) speedo, and with the connection at the right side of the engine case the extra few inches are ok.
OK gents, problem. I bought the recommended cheaper line (TK), only to find that neither fitting was the correct size. It was a case of sausage up an alleyway/hotdog down a hallway at each end. Unfortunately I don't have a micrometer to measure the fittings, so I'm hoping some eyeballing from you knowledgable chaps will help.
I have one cheap gauge around here, the male fitting measures 0.300", not sure what thread that is but the gauge came with an adapter to 1/8" pipe. I also have a Sunpro with an 1/8" NPT male, measures 0.38". Doesn't that kit come with proper male and female adapters? Did you change the adapter in your case?
Well I determined that both ends need to be 1/8, but I believe NPT is tapered, and these are not. I'll re-examine the adapters that came with the kit to see if they can be made to work. If not then McMaster Carr will be getting a call.
