Lets start a discussion topic

Simple proactive discussion
1.  What are the basic needs / requirements
2.  What are the concerns
3.  What will make a product better than the rest

Low profile rails
an style fittings
fits normal and rotated turbo setups
fits TMIC and FMIC setups
lines/rails equal length from dirstro block
parallel system
works with stock FPR or comes with after market one
fitting for pressure gauge
does not leak? lol
quality parts that don't rust

those are all great questions and ill address them all individually and if need to expand them individually


Low profile rail - why do you need them low profile  - as long as its not interfering with any physical part it should not matter providing its its mounted securely

an style fittings  -  It will be universal so not everyone is required to use AN fitting.  AN fitting is not necessary better as there are more junctions for possible leak it just looks better.

fits normal and rotated turbo setups - I can confirm it will fitmost setup but if you have an abnormal turbo and mounted in a cutom location then you will need custom parts.  No pint mfg for to fit all and cost o much that the rest have to pay extra for.

fits TMIC and FMIC setups - i dont think it matters but prove me wrong

lines/rails equal length from dirstro block - the way most fuel systems woks is it controls the back pressure so as long as your pump can deliver the amount used it does not matter how the fuel rails get the fuel, as long as its not in series.

parallel system - thats the main idea

works with stock FPR or comes with after market one - of course

fitting for pressure gauge - YES or provision for it

does not leak? of course

quality parts that don't rust  of course

Low profile rails are require for rotated setups. when the turbo is cocked sideways the intake tends to hit tall rails like the perrin ones. also by AN style.. I just ment lines that screw on.. again the perrin rails are hoses with clams and are pure fail imo.

I know what you mean that is taken care off on the LProfile (in an alternate way but may lose a function- optional feed method)

Do you know the stock hoses are clamped on - Why do you think clamp on hoses are bad ?  Experience or aesthetics

no experience other than the stock line that clamps leaking. I just feel safer with screw on AN style fittings. and yea aestherics =)

Ive not had any leaks on my 05 and 80k miles
and the ones that have leaks are a specific location that it was difficult to reach to tighten the clamp.

Even if i use AN fittings on all the rails and distributor -  the join from the OEM out and in line is still hose clamped.

To answer your needs
i will be providing the rails alone for parallel fuel feed and some extra features. And i will provide the types of fittings so the end user can choose the type of fittings - AN or Fuel Barb

There are about 12 fittings and each is about $5-6  for the AN type and $2-3 for the Fuel Hose Barb.

Here's the final pre production version goin into a car next week

Image = http://www.ixizconcept.com/ixizfrail/ixizFrail_AN.jpg

Shown are AN fittings
When offered there will be multi options with different connectors or no connectors

The rails will be about $140 a set
the connectors i will see what i can do in bulk  because the connectors were about $100 for the one in the pic
fuel hose a $5/foot (requires 4-5 feet) and another 2 feet for the equalizer tube.

Just my brainstorm from things i've learned on other platforms.  Take it as you will, it's just me thinking outloud:

1.) High pressure hose professionally crimped to fittings, a'la Eaton Weatherhead or Parker style.  It leaves too much trust to the installer to properly assemble a barbed hose and fuel-injection clamp setup.  We've learned this lesson the hard way on other platforms.  This way, the fitting and hose are an integral unit that cannot be disassembled and installation is more straight forward.
2.) Do not use commercially available "Fuel Injection Hose".  Use something higher pressure, preferably with a bare minimum of 500psi continuous pressure capacity.  Pressure spikes so close to the rail can cause standard injection hose to flex elastically, which tends to exacerbate the load on the injector solenoid.  A more rigid hose would prevent any issue.
3.) Reduced angle T fittings from 90 degree to 45 to reduce impact of pressure spikes on flow laminarity.
4.) Consider a bracket or block to keep the feed and return lines fastened together, so they don't rub on each other.  Either that or abrasion-resistant sleeving over the hose.

all above good comments
My initial offerings are two tier - fuel rails only and fittings only
The assembly will be done by end user - liability issues.  and there is no standardization on how the lines are routed so precut lengths will not fit everyones preference.

Ive recorded pressure readings on the fuel system and the spikes are very tame - that ive recorded
The system employed in fuel system uses the return pressure control and not feed pressure.  I like to know more bout pressure spikes and if there is an article i like to look at it.

If i were to offer fuel hose it would be R9 and will include a sleeving

I plan on not having any NPT fittings

Version 2b of the latest with improved fittings that is easily installed and performs better than V1
Ive only got 2 test sets and its reserved as soon as its on the car and running it will be in production
