Many times when installing an oil pressure gauge in a BMW or Mercedes there is simply nowhere to install the sender. There may be a blank plug, but the sending unit won't physically fit. In most cases there is a stock sending unit but no blank plugs. This is where our oil pressure relocation kit comes in.

Using our oil pressure relocation kit you are able to remotely install two pressure sending units in one port. Remote installation allows fitment of even the most bulky aftermarket senders. At the same time reduced engine vibrations allow for longer sender life.

Our kit uses a 12" hydraulic hose and M12x1.5 adaptor to properly tap into the BMW/Mercedes oil filter flange. The included hose is a stainless steel inner braid hydraulic hose capable of holding 10,000 psi and any heat the engine bay can deliver. The sending units are mounted on our custom CNC machined relocation block. This block is a simple Y shape and is threaded to accept the 1/8" NPT hose, an OEM BMW/Mercedes pressure sender, and a 1/8" NPT aftermarket sender. A built-in stainless steel ground screw assures the sending units are properly grounded. A built-in slot allows for solid mounting using a heavy duty zip-tie. Ground wire and terminal connectors are also included.

Worried about leaks?
Don't be. The relocation block and M12 adaptor have been precision machined and threaded. Using one wrap of Teflon tape on all threads will stop any and all oil leaks. As long as the kit is installed as intended there will never be any leaks! Each port is clearly labeled by engraving, so mixing thread sizes is nearly impossible.

Worried about mounting?
The kit has been designed in a universal fashion to allow fitment in all BMW/Mercedes models. The machined slot and included heavy duty cable ties will solidly mount the relocation block and senders anywhere the hose will reach. The senders can be routed downwards towards the oil pan, or upwards towards the intake manifold. Our only mounting location recommendation is that the block not be secured to electrical wires.
