Aquamist HFS-6 install into 97' LGT with 04' wrx swap: Pics Inside

morrocco88 · 02-10-2010, 12:17 PM

I'm almost finished with my latest build/version of my car and have added the HFS-6 to my list of upgrades. I want to document the install from start to finish so other people can se how it all works in one convenient thread. This will also allow me to ask questions along the way if neened and hopefully get them answered.

The car: 97' LGT with 04' wrx swap, built 2.1 stroker motor with 9.0:1 CR, fully ported heads with 264 cams, Blouch DOM 2.5R, v8 sti 6 speed with full drivetrain swap, FMIC. I wanted to run E85, but the closest station is 100 miles away. The HFS-6 will allow me to take advantage of the higher compression and run the boost and timing this combo deserves.

This is it on the dyno getting tuned for it's last homebrew setup including an EJ20G motor and piggyback ECU.

After much research and debate, I settled on the HFS-6. While researching tanks and install locations I finally decided to bite the bullet and get the Howerton Engineering twin tank enclosure. I bought the kit and tank system as a package deal fron Jeff and now that I'm installing I'm glad I did. Jeff has the customer service model to follow IMO. Answered all my questions and had great service after the sale. The best part is it came all pre assembled in the eclosure and leak tested before it shipped out. This makes the install at least 50% easier and the final install is so much simpler and clean.

I started with removing the factory cardboard piece and traced it against somethin a little thicker, cut it out and installed it in the car. I cut a door out of this one big piece to allow access to the spare tire. I then screwed the main outer piece to the floor of the car being very careful of the gas tank below. Once this was done i had a nice base for my tank enclosure and flat surface for the trunk carpet.

I took the cover off the tank enclosure and screwed the base of it to the floor.

As you can see this is the what it looks like when you get it and remove the cover. The pump and tanks are mounted and plumbed, the wiring with the relay is done ect. All you have to do is run the water line to the pump, run power/ground for the pump, and the Blue harness up to the control unit and the trunk section is done! Very nice Jeff!

I ran the water line out of the trunk and decided to run it along the door sill. I also made sure to put masking tape over the end of the line to prevent dirt/debris from getting inside. I lifted the plastic cover for the hard fuel lines and was shocked to see a spare/empty clip, so I snapped the water line right in and it fit perfectly! I did this the whole length of the car up to the front!

On that same side of the the car, up under the dash is the rubber boot where a main wiring harness goes through. I figured this would be a great place to go. I used a piece of coat hanger to poke through the rubber boot and taped the water line to it. This allowed me to pull it through with a bit of a struggle. The end result was a nice tight fit around the line keeping water and air out of the cabin.

Here you can see where it came out inside the fender area.

I was shocked again to see empty clip space on the plastic holders for the wiring harness, so I cliped the water line into it for a really nice install. It's almost if the factory knew i would install this someday!

From there I mounted the Flow Contol Module where the battery used to be (I re-located it to the trunk a while back to make space for a water/meth kit not knowing it installs in the trunk).

The water line will come through a hole in the fender with a rubber grommet to prevent chafing on the line, and hook into the FCM. I also ran the Blue harness from the pump along the water line to the dash area. I ran power and ground from the pump to the battery in the trunk. That is as far as I got, which is almost there thanks to the Howerton twin tank setup.

More to come, so stay tuned!

Please post a detailed install of where all the wires go as I am completely stuck on that part. Everything is ran to the DDS3v10 box but only the pump wires are attached. I'm stuck at where this black plug goes from the 40amp relay for the pump and where the Flow Sensor Module wires go.

So far everything you've done looks great!
