When I go for a test drive with the jet facing the windshield everything operates perfectly. No weak spray, no intermittent spray, it's just the gauge not reading flow. I checked the magnet it was clean as well. I'm running 50/50 meth

Check out my post about the aem flow sensor. Heat was causing the sensor to fail and I think all companies use the same flow sensor.

Hey guys I'm getting close to finishing up my build and have a NA long runner large plenium intake manifold that had been tapped for direct port meth injection. I was going to run the Hydramist V10 with a couple y connectors to distribute all 4, one into each runner with the JDM large water tank in the trunk. After talking to one tuner he says to just sell the Hydramist and do a Flex fuel sensor to run E85. I do have an E85 station close to me. I originally purchased standard an fittings for everything under the hood but now I'm changing to PTFE fittings and Teflon lined steel braided lines to be E85 compatible. Is methanol becoming obsolete with E85 being available? I'll be running AEM series 2 and the tuner says with the flex fuel sensor kit it can connect to the AEM were it can adjust the tune according to the E85 percentage.

What is the serial number of the HFS3?

Some history: The flow sensor is the item receiving constant improvement. It started life with a plastic body some ten year ago and evolved on metal body five years ago. That eliminated the engine temperature problem. Two years ago, a completely new internal design. I believe it was between the V1 and v2 version of the HFS3.

The latest flow sensor has an internal stainless disc filter.

Based on your answer of the serial number, I can look into this in more details.

It is not true for us...

The AEM sensor is sourced from GEM sensors:
http://www.gemssensors.com/Products/...ors/Turbo-Flow

It is 95% plastic, subject to high temperature instabilities. I believe another wmi company used it and later abandoned it after a years or twos later. It is not a reliable sensor for the automotive engine bay applications.

The aquamist sensor is solely designed and manufactured by us in house. We do not supply this sensor to any other wmi makers.

This discussion may belong to another thread. It is an opinion some holds dearly. E85 has its own unique set of problems.

Has gasoline become obsolete due to the advent of E85? Is cheddar cheese obsolete now that we have gouda? Different strokes for different folks but to answer your question, no. I run meth with my racegas tune and plan on doing the same with E85 just for the charge cooling effect.

It's definitely a sensor issue this morning when It was 52 degrees the gauge worked perfect this morning. Leaving the shop it was 90 degrees and even hotter under the hood the gauge didn't work at all

Does the flow sensor look like one of those?

While we are on the subject,

E10, E85 is relatively new compared to M10, M25, M100, WM10, WM20 etc. They just use a secondary delivery system. Went as far back 20th century.

I think MXX or MWXX will out last the EXX once the government subsidy is removed.

This is quite a warm location. all the hot air above the turbo is blowing towards the sensor. Can you relocate the sensor elsewhere? Near the right hand side.
If the line is too short, I can send you this fitting (6mm):

Yes ill need that fitting. My turbo is wrapped and has a heat shield so it stays pretty cool. Also it doesn't work even if the car just sits in the sun for the day. Only time it works is cold mornings.

It's been doing it for a few months off and on. I just haven't had time to diagnose it. Finally got around to it. This morning it was chilly and it did not work.

It appears temperature may not be the culprit. I have not heard one temperature related problem since the launch of the HFS3-v1.


It is possible some debris trapped inside the sensor tube. Are you good with mechanical parts? I suggest disassemble the sensor and give it a good clean. Do not use compressed air as it will destroy the bearing surface.

Yes I'm very mechanical. I will pull it apart today and give it a shot and let you know what's going on thanks Richard

All internal parts are replaceable. Do not over tighten the assembly, sealed are all o-ring based.

Before disassembly, blow gentle on both directions, it should be the same. Also shake it back and forth, it should shuttle freely.
