Twin feed line kit for the EVO8-9, no hacking required.
Twin feed line kit for the EVO8-9, no hacking required.
Hi guys,
Many of you have followed the build up of my RS, the original Bad Bish and of the new Project White car I built. Also as many of you know we offer a double pumper fuel system that consists of twin intake Walbro fuel pumps, easy installation, no cutting into anything including the wiring. The standard double pumper has two outlets that feed into a wye fitting and then runs to the front of the car through the stock 5/16" fuel feed line.
My RS was running out of fuel last year and I was getting a lean spot right around peak torque. I was fairly certain that the car had run out of fuel line with the single 5/16" line.
A few months ago John Shepherd asked me about running another fuel line as he is running pretty big power in his EVO on E85 and we knew it was going to run out of fuel too. He mentioned to me the factory vent line on the EVO and wondered if we could get it to somehow work.
I got to work on the RS and cut the vent line and then simply ran two seperate lines out of the double pumper, one to the factory feed line and one to the factory vent line. Then under the hood we ended up with two fuel lines about one foot from the fuel rail.
I then had to have a lot of parts made. We had new fuel rails built, adapter to go from the fuel rail to a -6 inlet, a custom CNC'd wye to go from the two 5/16" lines to a single 3/8" feed line.
The results were excellent. Where I had a lean spot at peak torque in my car on the dyno it nearly disapeared and the AFR's dropped 1 full point richer, so from 13.4:1 to 12.4:1. The rest of the fuel curve also got richer, this showed me that the problem was actually in the fuel line.
I just finally got all the parts together to offer for doing this.
The parts will be made available in the smallest package possible, which is what will be shown in the picture in this post. You MUST already have OUR double pumper and an upgraded fuel rail already.
Keep in mind, this is for cars really pushing the limits. My car ran 9.0 at 159 safely and made 684 whp on our dyno on our standard double pumper, single stock fuel line and 1200 cc injectors.
I am at the point now with the car that it is making over 700 whp and I am now out of fuel again, even with the twin lines, on the 1200 cc injectors.
What this does it increases the fuel flow to the rail so that 1600 cc injectors or sets of injetors in a twin rail set up will not run out of fuel. On a twin rail set up you could run one fuel line to each fuel rail like this, one Walbro feeding the primary injectors and one coming on to feed the secondary.
Here is a picture of the kit:

The pricing on the kit pictured is $270. This will get you twin lines to the front of the car. We will post installation instructions on our website and pictures. I don't want to post them here as of yet.
The fuel fittings we had made are all anodized so there will be no problems with ethanol, methanol or E85 etc. Clamps are all stainless steel, fuel filter is also stainless steel. The fuel line is also multi-fuel compatible so it will also hold up to E85 and such.
If you buy the double pumper and want this at the time you buy the double pumper the price will be discounted on the entire kit by $80.
Thanks for reading.

Are you using normal fuel hose and double clamps for the junction between the end of the stock fuel line (and the stock vent line) to feed the "Y" to the fuel rail?
Is that because it's a pain to find a fitting that replaces the stock fuel line fitting at the hard to soft line junction? Do you feel comfortable that that setup will hold 100+PSI of pressure?
Just trying to understand how the parts that are in the picture go together. Thanks for the reply.

No further instructions are being posted for reason like "home depot mod" comments.
Go and price the Gates Multi fuel line, SS Oetiker clamps, SS HP fuel clamps. the SS 10 micron filter, then have the wye CNC'd (it's not made by anyone in any industry now), get the fuel rail fitting CNC'd too and put the -6 swivel fitting in. Get back to me on the price to do that, home depot mod. Let the douche bags that come up with the write up on that also come up with the solution instead of once again copying someone else's hard work.
The cars have been out since 2003, 6 years. In 6 years, until we released our double pumper, the solution to fuel an EVO at high horsepower levels were fuel cells, braided SS lines and basically hacking up a good car.
The funny thing is the "home depot" comment pissed me off and the fact is I can bet money it came from someone with a 300 whp EVO that will never need this anyway.

Gates fuel line: $16 per foot (retail)
Oetiker SS clamps:$14.99 (per 100, retail)
SS 10 micron fuel filter: $16.99
Earls swivel fitting: $5.99
Stainless Y fitting: $24.95 (retail, each, can be bought in lots from eldon james for less, but 6 week lead time)
The fuel rail adapter depends on who you have do your cutting work, and how large your batch size. I'd guess it's pretty small, so therefore, possibly pretty pricey since most of the machine time is for setup and tooling and very little cutting time.
I understand you're in business to make money, and in these times we all need every cent we can get. This particular kit just didn't quite seem to justify the expense for me. Granted, I'm sure there will be people willing to pay for it, and I have no doubt it will perform as advertised.
And for the record, my evo makes 340whp (dyno dynamics) which is probably somewhere close to 300whp on your mustang. Maybe we should start calling you Cleo! But hey, it doesn't hurt to dream.

IMO, this is a good setup for a reasonable price.
$222.92 with 10ft of fuel line. Is it really worth the $60 you will save?! Not to mention that you still have to pay for shipping on all your parts and then you have to be smart enough to DIY or pay $xxx.xx to a shop to do it for you.

The kit as pictured is what is 280.00. Not from the tank to the fuel rail. Shipping comes into effect for his kit as well. It doesn't say 280.00 shipped.
I wasn't trying to bash Mr. Buschur at all. Rather, I thought is was a misprint based on what I saw in the picture. Now that Dude was kind enough to post prices, I now know that I was off by at least 100.00. Sorry about that Mr. Buschur.
Everything in the picture is available to anyone who looks for it. There is no need to have any of it manufactured. Even the "CNC'd" -6 fuel rail adapter can be had for around 15.00 if you search for it.
Based on the parts shown in the pic there is about 120.00 dollars worth of stuff there retail. Definately Mr. Buschur should be rewarded for his time and ingenuity. I guess how much will be left up to all who purchase this kit.
Love to see the innovation...I am liking your new trend to build as OEM-like and to not hack up the evo mods...+1 for coming up with the idea and +1 for charging a fair price for this, let the haters build it themselves...
Are you using normal fuel hose and double clamps for the junction between the end of the stock fuel line (and the stock vent line) to feed the "Y" to the fuel rail?
Is that because it's a pain to find a fitting that replaces the stock fuel line fitting at the hard to soft line junction? Do you feel comfortable that that setup will hold 100+PSI of pressure?
Just trying to understand how the parts that are in the picture go together. Thanks for the reply.

Still looking for answers on these questions...
