Question to anyone with an EG/DC chassis.

Currently doing a brake line tuck in an EG Chassis.

I'd like to know whether or not it matters how the brake lines are routed to the prop valve.

If you look at this pic below, it is routed one way (OEM I believe)

However, I went ahead and did some more research and noticed these are routed differently then above

My main concern are the four (4) lines coming into the prop valve. Two from the BMC and the two that go to the R/L brakes. Just want to make sure they can be routed either way or if it has to be done the same as OEM

kev someone asked me about where the lines went and such so here is an illustration. Just if someone else had the question of how does the factory have them.... or least thats how it was on the hatch and verified with the teg prop valve.

June, no prob

1. Flare Tool

you can use either a bubble flare kit or a single flare (AN) kit, depends on what fittings you use

Double Flare Kit

2. Tubing

3/16" tubing is what is to be used.

You can purchase them as straight line locally at your Autozone, NAPA, etc.

Can also be purchased as a 25ft or 50ft coil, depending on how much you need.

Coiled - Can be easily bent by hand however, the finishing product isnt beautiful as the lines do not easily straighten

Straight - recommended, as these allow for some nice bends.

3. Fittings

a. Inverted Flare Fittings - Used for the double flare kit. If you're on a budget and cant afford the AN fittings and would rather pick it up locally, best option to go with. They arent pretty but are similar/same to OEM

Note: These are meant for the BMC and Prop valve. if you plan on going through any part of your chassis, i recommed using bulkhead fittings with the required -an tube nuts and sleeves I listed below.

You can drill through and run the tubing as is, but this will be difficult. TRUST ME.

b. AN Fittings - You will need the following

PLEASE NOTE:
I did not list a quantity required for each fitting. This DEPENDS on you, the user/installer and how you prefer your lines to be routed.

4. Tools

a. Bending Tool

Tube bender you decide to use can allow for large radii or small radii bends.

I went to Harbor Freight and picked up this bad boy. This allowed for small bends in which I prefered.

b. tube cutter

You can use the mini, which i preffered

or the normal type

c. For double flare fitting, recommend using a flare nut wrench.

10-12mm to be exact

manufacturers i used in this example are subject to who you prefer. Can range from Fragola to Earl's to Aeroquip. Really depends on you.

Please let me know if there is anything else you guys would like to know or think I forgot to mention.

Hey, sorry for the late reply.

Quantity used is solely up to you, it really depends on how you plan on routing them. I wouldnt want to give you a number and you end up having less than more.

In my EK, i didnt do a brake tuck, however, I recently helped out a friend with theirs.

The rear lines are personal preference, my friend i helped opted to have them exit through the exhaust tunnel and connect the new lines to the existing lines from there. here are some pics

hey, i'd personally stick with the EK prop valve. The EM1 and EK hatchbacks are the same PV. if it's what came with your, use it. Personally i've never used an EG PV or seen/heard of someone using it in a different chassis

Looks sick.
the car its in is coming along beautifully, linked above my post.
