Has any W211 E55 owners installed a meth pump inside the front passenger fender, beneath the washer pump (like post 79 in this thread https://mbworld.org/forums/w211-amg/...ethanol-4.html)?

I ask because when I tried a test fit the pump would bulge out the fender. I know others have - non E55s - but curious if any E55s have does this pump fender install. Thanks ahead for any response.

My water injection pump is near the front bumper

mm....most likely what I will now do. Is yours passenger or driver side, closer to bumper? You by chance have pic?

I mounted mine close to the washer tank in my 05 E55. If you remove your fender liner there is a spot big enough for the pump where the liner meets the plastic floor tray.

That is the same place I put mine. It tucks away nicely there.

Scoto and boostedfe3, when you mounted it at your location...did you mount it horizontally or vertically? I having a hard time visualizing it.

scoto

I could get a photo for you this weekend. when you remove the liner you will see the spot.

If you do, that would be much appreciated!!!

Hulk

I got a pic
I will find it
I put it near the front bumper for easy access in case you need to change pump etc

Hulk

Best I can do
I had more but changed phone

Mine is below the washer tank near the bottom of the liner. I may have a pic somewhere.

Thanks. I took a look under there tonight and I have room to install my meth pump there too. A lot easier then under fender. Thanks again.

Hulk

Yup much easier

Quick question for ya Hulk. With your pump mounted by the bumper, where is your tank located? I assumed the windshield tank sits lower than where your pump is installed so you are using a different tank. What tank are you using to feed the pump?

Hulk

Washer tank, It's the same level and that's fine

nanayaw6

Got it. Thank you sir!

Does anyone know if the Aquamist level sensor will fit into factory washer fluid tank?

You can drill a hole and fit the aquamist sensor, but you also have the factory sensor in the washer fluid tank.

I was going to omit the aquamist level sensor completely since there's a factory sensor, but I believe the HFS may use their sensor as one of the failsafes in the controller. If anyone knows if you can run without it I will gladly omit having to have it installed.

Hulk

That's what I thought when I saw your post, but I think there are 2 other fail safes so ask Jeff what he thinks if you don't use the fluid level.

jmb614

Thats a good point. My thought was that if there isn't a signal coming from the level sensor the controller may not inject. I'll shoot him an email.
