Q Catcher Posted February 22, 2018 Share Posted February 22, 2018 Has anyone gone to the trouble of fitting one of these (i.e. combined) gauges on a K-Series car? (I'm planning on fitting an oil pressure gauge, with the mechanical capillary, to get rid of the nuisance failures of the OE pressure sender, which I've somehow put up with all these years. But just before I do, has anyone fitted a combined one?) If so, is there a good point from which to take the temperature reading? And in any case, whether combined or not, what length of capillary have people used for the pressure side of things? The ordering options are apparently 7, 9 or 12 ft.

Member Jonathan Kay Posted February 22, 2018 Member Share Posted February 22, 2018 Have you found the general guidance and parts list for fitting a mechanical pressure gauge? I think there may be a blog or Guide somewhere... ?And, specifically on Racetech.Jonathan Link to comment Share on other sites More sharing options...
Silver Machine Posted February 22, 2018 Share Posted February 22, 2018 No experience of the combined gauge. Length of tubing to oil pressure gauge is determined by the route you take. On my K series I routed from oil pressure sender connection round the front of engine then up the drivers side and into dash. Each car is individual and may/will determin the route. Run a piece of rope on proposed route to get approximate length for your instalation. You can always loose a bit with slght loop at dash end if a bit to long. I would presume the temp bit is easy in that you connect the wire from oil temp sender to the back of the gauge. Think my oil temp sender is on the appolo tank. Hope some of this may help.

glasgow Posted February 22, 2018 Share Posted February 22, 2018 I have SPA digital combined oil pressure/temp gauge. It comes with all the wires needed. You don't need to do any measurement if you are going to put the 2 senders in the oil filter housing (via T shape connection). However, I wanted to move the senders away from this "vulnerable" place, so I connected them to the filter housing via a small hose. The 2 senders comes with their standard wires which are too long so you just loop them. I ordered all the items (including the hose) from Think Automotive, however, you can get them directly from SPA. Happy to send you the parts list if you wish.I have the gauge for 2 years now and very happy with it. A bit pricey but I never liked the idea of having oil tube inside the car.

alan c Posted February 24, 2018 Share Posted February 24, 2018 I cannot help with your specific installation but I have had the dual race tech gauge on my VX for many years now with no problems Link to comment Share on other sites More sharing options...
andymal Posted February 24, 2018 Share Posted February 24, 2018 I have a combined gauge on my K series and think it is Racetech (can't be sure as the car is at a different location). The temperature reading is taken from the bottom nearside of the bellhousing tank but may have been placed there as the most accessible place to tap with the engine and box in situ.

Area Representative Richard Price Posted February 24, 2018 Area Representative Share Posted February 24, 2018 Ahmed (Glasgow),is is your oil temperature sender in a remote hose? If so, is that hose a dead end? If it is a dead end, then it won't accurately show oil temperature.i have a sender in my dry sump tank (having previously had it in an apollo tank). I find that oil temperature lags coolant temperature significantly, but with road use, eventually gets close to coolant temperature. With track use, oil temperature exceeds coolant temperature.

Area Representative Richard Price Posted February 24, 2018 Area Representative Share Posted February 24, 2018 Q Catcher,of you're going to use a capillary oil temperature gauge, you'll need to ensure your measurement is taken where the oil is stored, or is actually flowing past the sender with good contact. If you have an Apollo tank or dry sump, it's much easier to do electrically using a standard sender and having a changeover switch for the standard temperature gauge.

glasgow Posted February 25, 2018 Share Posted February 25, 2018 Richard,Sorry, my reply above is wrong. I actually put the oil temp sender in the oil filter housing as suggested by Revilla in post #3 in the following thread:https://www.lotus7.club/forum/techtalk/location-oil-temp-sensor-k-rover-wet-sum-no-apolloand here is Revilla pic I used:The oil pressure sender is attached to a 300mm blind hose. Apology again Link to comment Share on other sites More sharing options...
Q Catcher Posted February 25, 2018 Author Share Posted February 25, 2018 Thanks, everyone, very helpful. I particularly like Revilla's solution, so thank you especially to Glasgow and Revilla. Link to comment Share on other sites More sharing options...
rj Posted February 25, 2018 Share Posted February 25, 2018 I've cut a thread in my sump pan. Am I the only one to do that? Link to comment Share on other sites More sharing options...
