Hi Fergie,

I simply know it as the fuel filter sensor. It can be one of two types depending on the filter housing. It is designed to indicate a build up of water and sludge to set levels. Once the build up goes over these levels it can be drawn into the filter and subsequent locations thereafter. Water and IP/injectors do not mix well.

It pays to keep this sensor well maintained and include a partial drain of fluid from the base of the filter in your maintainence schedule just to check on water build up. On old sensors I have also noted that sludge/grunge has prevented the float trigger from moving thus rendering the sensor useless. Check it periodically.

Hope this helps.

Cheers

Phil

Hi Fergie,

I tried replying to your PM but kept getting an error message from the site server.

I ordered my new one (some year and a bit ago) via Nissan dealership here in NZ. Arrived from Japan within two weeks. I'll look out the receipt for the part number tomorrow then I'll see if I can find one online in some of our FLAPS here. May well be some replication between models of Nissan if not other marques as well.

Cheers,

Phil

Sorry Fergie,

I've looked through two folders of old receipts to no avail. Odd because I seem to have keep all other invoices and it was worrying to see how much had been spent! :roll:

Fuel Filter sensor element

The part number for the fuel filter (fuel/water seperater) element, per Nissan, is 16470-W1701. I am not sure where to get it at this time. Mine is broken (wire came off). I just empty the filter from time to time. No problems with my pump.

From this thread in Nov2007:

Nissan FAST lists two different Water In Fuel sensors: Image

Nissan FAST actually lists three Water-In-Fuel (WIF) sensor probes:

All Nos. turn into 16412-V0701, according to my dealer. So, though I ordered one of each, what I received was two of the V0701s.

Note that the WIF sensor probe does not come with the mating o-ring.
