started tear down for paint
Where is the ac drier? I was thinking there would be plenty free space over towards the pass. headlight-ish area, but that may be a little far.
one end goes to the sender which goes into the engine, the other end from the same SS hose, where does it go?
does it go into the cabin and plugged to the back of the gauge?
if yes, then braided line must be sealed when going through the front
firewall, don't want any water drippin' inside the cabin.

that would be stupeed!
is it this way you had in mind fitting a braided line under dashboard re-routing the braided line?

The only thing going through the firewall will be wires.

The stainless hoses do not connect up to the gauge, they just connect the engine to the sender. The sender is mounted to the end of the hose; wiring runs from the sender to the back of the gauge.
Ideally, I would remove the lower oil pan and drill a hole in the side of the pan for the oil temperature sender. I wouldn't remote mount the oil temperature sender because if you do, then you are going to get cooler temperature than if you were taking the reading out of the pan.
The thread pitch on the oil test port is M12x1.5.

you just press the hat onto light bulb.
our clusters have orange illumination, it will look weird if you have three 52mm gauges with other than orange backlit color.
ask your nearest radioschack dealer if they can sell you 3 rubber hats?
I am curious if you're ever going to need that adapter for oel pressure sender?

should be close enough for me
Adapter screwed in the engine block. SS line attached to the end of the adapter and finally the sender to the other end of the SS line. Electric wires attached to the sender. Wires go through the firewall and attched to the gauge. Bingo, you have a reading

thanks man

One end goes into the sender and the other end goes into the adapter at the engine test port

Adaptor material I don't think really matters. Steel for durability (like if you expect to remove the line frequently), aluminum for looks or weight savings (as if it would be noticeable though...).

AC drier is basically next to the power steering pump on the driver's side.

I spent some time trying to find a good way to route the flexible line without using this scheme. I thought about running the flexible line inside a soft copper tube, and bending the copper to route the line away from the belt. I had no success beyond the tubing, and resorted to doing it the old fashioned "hot rod" way.
The good thing is any leak would develop slowly, allowing ample time to repair the leak.
If any of you use these methods to add an oil pressure gauge, be sure to replace the port gasket, as they are prone to leaking.
I do like the idea of remotely mounting the sender if you are using an electrical gauge. This would keep it away from the belt, as some of the senders are a little large.




fishing for an innocent net surfer. I have reported to admins
The Best of Mercedes & AMG




don't want any excessive length looking bad in da bay.
Been browsing SAABO's engine pictures.
It begins to worry me about the chunkiness of oel pressure sender + adapter.
When the belt is fitted there's very tight place to fit the sender if it can be fitted?
I bet it will poke out a lot near the belt route.
Check these engine pictures from different angles and tell me there is a problem or there are no problems fitting chunky sender?

Remember, the sender will not be mounted to the test port directly!! The sender will be mounted to the far end of the hose, the near end of the hose will be secured into the test port.
NHmercracer - definitely old skewl to use a mechanical gauge! I think I would use a mechanical gauge for vacuum or boost, but hot oil right into the interior of the car? Brave!

Another note - if one uses AN fittings (ie, the -3 or -4 hoses I mentioned), they do not need thread sealant, as they fitting is tapered.
Dennis, I suggest you download a Goodridge, Aeroquip or Earl's catalogue from their respective websites. Lots to be learned about which fittings and such are available.




-4 male to M12x1.5 male adaptor - 9919BFGERL (plugs into the test port)
45* -4 female to -4 female adaptor - 939204ERL (plugs into the adaptor above)
-4 hose, 12" (~30cm) pre-fabricated hose, with -4 female fittings on both ends - 64191909ERL (plugs into the adaptor above, and then into the adaptor below)
-4 male to 1/8" NPT female gauge adaptor - 968704ERL (sender plugs into one end)
Note, however, that metric gauge adaptors are quite hard to come by in North America, so I spec'd out a part for the far more common (and cheaper!) 1/8" NPT senders. Also, the hose length would still need to be verified. I'd actually measure it prior to purchasing.
Add in some cable ties to keep everything secure, and done. At least for the mechanical assembly - still need to run wiring from the sender to the inside of the car.
Guessing that the cost of these parts would be about C$60-70, based on prior experience.

You could eliminate the 45* fitting and the pre-fabricated hose by building your own hose, I've done this before. Then you would just put a 45* fitting on the end of the hose. However, the smaller the length of hose, the harder it is to cut the hose nicely - so for the smaller fittings, I've always preferred to use off the shelf hoses.

30 -0+ 30 amp
60 -0+ 60 amp
100 -0+ 100 amp
150 -0+ 150 amp
which one is suitable for C43?
a gauge with 100 or 150 amp scale?
this is a 150 amp gauge

A voltage gauge is ample sufficient (and probably cheaper too)...
maybe it will be difficult to install the oil pressure gauge sender, so if I ditch this oel pressure gauge and replace it with something else like an amp gauge instead, donnoe what to buy yet?

the others I'm gonna get are volts and oel temp gauge.
3rd one is still a ?








-4 does not equal M12x1.5. The latter is metric of course, the 'dash' sizes are AN threads, which stands for Aeronautical/Navy or something like that, it's a military specification dating back to the Second World War. It has a tapered fitting on the ends and it meant to carry fluid. Just about all of the aftermarket hoses you see from Earl's or Goodridge or Aeroquip, the braided stainless hoses, are AN sizes.
how many bots are screwing this cubby compartment in place?
is it 2 in front of the gear selector where original screws for ashtray is bolted?

Well your way is looking quite nice right now, as indeed, no one makes (or even wants to custom fab) a hose with m12 x 1.5.
-4 male to M12x1.5 male adaptor - 9919BFGERL (plugs into the test port)
45* -4 female to -4 female adaptor - 939204ERL (plugs into the adaptor above)

One more question for you, how does the 45 degree attach to the hose? Aren't they both a female end?
Sorry SAABO I now realise we have hijacked your thread.
Pliz forgive us.

It's always time consuming to figure out exactly what is needed, but when it does come together, it's always very nice too!
