I'm really not familiar with how the plumbing works on our cars in the fuel area guys and i'm trying to learn and understand a little more here on our good ole' forum... and my car is in the shop so I have nothing to just go outside and look at...

I know I need to upgrade a few little things in my fuel system (i.e. injectors) seeing as I have a completely stock fuel system on the car with

LQ4 6.0 364 c.i.
AFR 205cc Heads
224/224 .581 114lsa Cam
TSP Lid + K&N
BBK Intake Manifold
BBK LT's and ORY
Magnaflow Catback

DYNO = 446/416

and a few other non-relevant mods...

I've been told I should pick up a set of 42# injectors for my setup... seeing as I'm pretty happy with my power and won't be doing much more in the performance area...

I've been looking at fuel rails as well...

In my searches, most people have been saying that the fuel rails are more of an appearance mod than anything. But even so, I've been looking at different kits out there. I really like the looks of the RevExtreme kit (pictured below).

However, I'm a little confused as to how the fuel lines from the car connect to the new plumbing of the FR Kit... anyone have any detailed pictures of that area, and how to disconnect the stock fuel lines from the stock fuel rails and how they connect back up to the aftermarket ones?

You can kinda see it in my pics of my fuel rails I posted up for you...basically you need a SAE J2044 quick disconnect fitting to connect to the hard line. Russel makes them that adapt to AN fittings, as does Aeromotive. If you use the Russel, it is a straight connection to an AN fitting (-6AN I think). You'll need a 3/8" for the supply side hard line, and if you want to do a return using the EVAP, that one is 5/16". Aeromotive also makes quick connect fittings (which I really like), but they are expensive, and also require that you also use one of their straight cut o-ring to AN adapters to make it work. Kinda hard to explain, and I don't have good pictures to illustrate this.

Once you have that hard point connection taken care of, just run the line straight to the rails. It really isn't hard once you have the parts in front of you...you really just kinda need to be familiar with running stainless braided line, and how to install the hose ends...my Earl's line always comes with really good instructions, and I've never had leaks.

As for disconnecting the stock lines, you'll need a quick disconnect tool from your local auto parts store. I recommend the plastic ones (comes in a pack of 5 or so, all different colors). Just put it over the hard line, slide it into the end of the quick disconnect, push forward on the line, and then it should pop right off.

 

cool thanks man... i take it when you disconnect it, fuel doesn't start pouring everywhere....?

 

It sure does...either get a cup, or just let it spill. It'll seem like it keeps pouring out forever, but that's life.

 

does it? how much?

 

Whatever is left in the rails and the lines...I'm not really sure how much, but it usually seems like it is a lot more than it really is.

 

Alright I'll be prepared

thanks MeentSS02!
