I am looking to upgrade my fuel line from filter to fuel rail and replace the small diameter loop.
Can someone point me in the direction where I can get the 4 adapters attaching the line and the loop to the fuel rail?


Thanks

If you are ONLY looking for the adapters, then vendors will carry them e.g. 3SX and Ninja Performance. They also carry full kits unless you plan on assembling your own lines with fittings.

The other option is to just weld male AN ends directly onto the rails - eliminate o-rings.

That way you only get to use top quality efi hose instead of what you buy from the parts stores which is always very low quality and ends up cracking after less than 2 years. Use the proper mitsubishi fittings that are designed for the fuel rails, Waste of time and effort trying to weld expensive AN fittings to the rails when you can use the correct fittings instead. At the same time you have the option to use 2 factory FPRs, one on each rail, that gives superior pressure regulation when you fit a bigger pump. At the same time it eliminates the loop between the rails.

If you are going to keep the stock fuel routing, and just want an upgraded loop, the EK2 fuel loop kit on ebay is great.

OK for cosmetic mods, as far as function goes, it's a pointless ricer mod.
About as pointless as dual stock FPRs that aren’t needed lol.

Ray Pampena already proved on the dyno that on E85(30+% extra fuel volume over 93) past 600whp the stock fuel rail loop produced a 1 point AFR difference between banks with the rear being leaner. The upgraded fuel rail loop fixed that. His “racecar” fuel mods include stock rails, stock filter, stock FPR, stock fuel lines, hotwired Walbro 450, ID1300 injectors, and an upgraded fuel rail loop. Grand total held 717awhp and 747awtq. KISS. There has been a lot of misinformation on our fuel system spread for years and Ray set things straight. It’s bad enough most of these cars turn into jack stand queens. If it ain’t broke don’t fix it.

As far as the fuel loop goes. any difference in fuel pressure between rails will be at it's most at idle and at it's least at full power.
That's If you understand how a fuel system works. So NO, he didn't measure a whole point between banks, not due to the fuel loop.
Therefore what you've just said makes zero sense .You're just repeating on what you've been told that was wrong rather than telling your own first hand experiences.

No 6 always runs the leanest but that's because it's closest to the throttle body and gets most air. To find that problem you've got to pull the plugs, To fix that problem you need twin throttles,

The fuel loop does absolutely nothing for performance.

E85 actually needs closer to 50% more fuel by volume not the usually quoted 30%

About as pointless as dual stock FPRs that aren’t needed lol.
For 2 pumps you actually need 3 of them.

The difference at idle with a single walbro pump is 5 PSI, that's going from a single FPR to twins.
It brings the pressure back so it's within the factory spec.

You need to quit spitting out nonsense Steve. Geez there are a lot of false facts in your reply. I’ve made 680whp through the stock rails, FPR, filter, lines, and an upgraded loop. I took Ray’s recipe on 3.0 DR-750s and had identical results. You sound just like Steve68 that used to be on here. I’m not going to argue with a troll when you’re wanting to discredit a pioneer and guru of these cars - Ray. The proof is all out there in threads here. GL.

False. 30% is generally the rule of thumb, but it varies by E% of your pump gas and of your E85. Of course you fine tune from there, but 50% is way too much. Even E100 has 65% of the energy content of gasoline with E0. If you are going from E10 as is typical for pump gas to E85, you would need to increase fuel by volume even less. I recently switched from pump gas to 50/50 pump and E85 to full E85 and it was nowhere near 50%. Infact 50% would mean i wouldnt even have enough pump or injector.
Official documentation: "1 gallon of E85 has 73% to 83% of the energy of one gallon of gasoline (variation due to ethanol content in E85). 1 gallon of E10 has 96.7% if the energy of one gallon of gasoline." see attached

So all you can manage is personal insults?

Try better?

Where are the facts wrong....one at a time if you can?


Your car probably doesn't even go and if it does it probably drives like a turd
The fact that it can make xx hp is completely irrelevant when it's broken.

Energy content of fuels

Fossil and Alternative Fuels - Energy Content (engineeringtoolbox.com)

conventional gasoline, 34, 613 MJ per cubic M
Ethanol 23,531
So that's an extra 47% you need for E 100 at lambda 1
If your E85 is 85% then you're looking at about 40% more.
As far as volume goes at full boost, it depends on whether you're doing the comparison with race fuel or pump fuel.
Comparing to low octane pump, you run it extra rich so the difference in required volume is a lot less than with race fuel.

if your 1 gallon of E100 has 65% the energy content as you say above then you need 54% more by volume.
If your 1 gallon of E85 has 73% the energy as you say above then you need 37% more
If it's got 83% then you need 20% more


BTW both my cars are on their original fuel filters.

Why replace them?

Pressure and flow tests along with voltage and amperage tests show that they don't need changing.

Go think on that for a while?
It always beats trying to fix problems using nothing but guesswork.

Not that my home boy and hands down a among the top most knowledgeable 3SI specialists ANYWHERE, needs any help defending his Superior knowledge and ability, I can see for a fact that turbo since birth knows exactly what are you talking about when he makes effectual statement otherwise he won't make a statement and if he says information is wrong, then the information's wrong. Not to mention the fact that he references his sources and his evidence of such. Well most people commenting on most websites fail to cite sources, it's refreshing to have people that do. Especially people who have been members of a site such as this one for extensive amount of time absence any disruptions or interventions by staff members or mods or anyone. So I would suggest that my bro and his record speaks for itself when it comes to who's the most reliable source regarding whether you or he knows more about this specific platform. Not that you don't know anything Steve. But I know turbo sense birth will not simply State something directly with such confidence unless he can back that statement. AND he can admit when he doesn't know somrthing that's a sign of a person who truly knows their s***!

Peace
