Custom fuel rails....?

[Helldog]

I'm not sure about other Z's but I think they're kinda like mine but....You know all that rubber tubing for the fuel rail?? Well, I've had to change those tubes several times and it's definitely not easy and not fun. Anyways, I'm just wondering if anyone knows anything about getting custom fuel rails made so I don't have to deal with those damn rubber tubes. That way I can also get a performance upgrade at the same time. I thought about exchanging the rubber tubing with steel braided fuel lines..if they have them...but I think that would be a pain to cut. Well, I just want some thoughts because sooner or later, when I have the money, I want to do something about my fuel rail.

I needed to replace my fuel rail, and I got a really nice one from Pallnet.

I looked at that website and those seem pretty sweet. How much better does your z run now with the custom fuel rail? Also..how hard was it to put together and get it working right? I'll be sure to look into getting one. If anyone knows anything better or knows any other websites selling cutsom fuel rails just post a reply.Thanks anyways.

From what I hear, Pallnet includes EVERYTHING to install the rail on your car. I don't know if it will make your stock car run better, but if you have bigger injectors, it will allow enough flow to let them do their job. Email Pallnet about your car, and your questions. He will answer, he is a great guy to buy from.

First of all you can get different rails for the car, depending on what injectors you have. Contact Mr. Allnet for details.

It wasn't very hard to put together, but It did take a lot of time preparing the pieces (hoses & fittings) so it was just right and it went together. Remember- trhis is a FUEL distribution system, and it's under HIGH PRESSURE, so it needs to be done right. Pallnet can get you all the fittings that go on the rail, but you might need some others to hook it up to the car, and some pieces you need to get yourself.Mr. Allnet can help you with that.

Assembling the rail takes some time to do it right (injector barbs, pressure gauge, in & outlet), then you can mount it to the engine. You get brackets to support the rail. I used short hoses which were stiff enough to support the rail, so I don't have the brackets on (yet). Then you plumb in the fuel supply & return lines, and maybe some fancy pieces.

I just had the engine tuned to specs by a Nissan tech, so I'm getting double the MPG of before ( very detuned/less MPG) but I don't feel any more performance, since the limiting factors are the injectors, pistons, valves (rest of the engine).

If the rail uses barbs, aren't you still using short bits of hose that will still be hard to replace? Granted the rail will have fewer problems in removal(original is formed around the engine and is fastened under fasteners holding other things)? To me, the most difficult part of working with the injectors was replacing that 2.5" section of hose between the injector and the rail-doesn't sound like that problem is addressed by that fuel rail.

TomoHawk, you've been there and done that-is it better?

When I tool the old rail off, I just used an X-acto knife to cut the hoses free of the rail, then the hoses off the injectors. Then I removed the injectors from the intake and sent them to www.witchhunter.com to be serviced.

BASICALLY:

To re-attach the rail (barbed/stock injectors), I first put the hose pieces (8mm or 5/16 hose) on the injectors, and the bottom clamps & tighten those, then slide on the top clamps. The rail has all the barbs on it, so I just lined up all the barbs to the hoses and worked the rail into the hoses, then position & tighten the top clamps. Then attach fuel lines, etc.

It's not that hard, but it has to be done right. All 6 hoses are done at once. It sounds like you did them individually, which I consider to be impossdible.

Just takes some time.

thx

TomoHawk,

I did pretty much what you did, but with a razor blade.

Still a major PITA. The hoses were varnished onto the nipples-I actually had to shave the rubber off both the injectors and the nipples-raises my blood pressure and cholesterol just thinking about it...

No, not a PITA! Repeat after me, " It's fun working on my car. Relaxing. "

Of course, I did mine in the (Ohio) winter on the weekends, so no rush.

I still recommend you send all the injectors to www.witchhunter.com. He will check the initial flow rate, clean them by media blasting, then flush them out totally & recheck. Mine were about exactly matched after flushing. Very affordable too.

Oh- send him the cold-start injector too.

i dito that if u want a good fuel rail go get pallnet rails. u will hear nothing but good things about him.

There are others that are making their own fuel rails. Will is trying out his own design, so is the guy that runs www.cruez.com . You can even get the raw stock and drill & tap your own holes the way you want them even.
