A little help from you nitrous gurus i have a few little questions.

first off.... were do you "T" off the fuel line? (pics would be awsome).

second... what color is the TPS wire comming off the throttle body?

third.... Which wire do i tap to hook up my digital window switch? (i've heard its the number 1 cylinder.) which one is number one and were is the wire/color.

thanx in advance sorry for the newbie post and i did search.

Do a search on the SPX Fuel Tap. It allows you to bolt an 1/8" NPT female fitting into the stock fuel system that you can remove later if you ever need to.

 

i read up on the SPX system and i dont really think i want all that hassel.. i'm just going to "T" the system. (i dont care about the dealer). but thanx for the input.

can anyone help me with my questions?

 

fuel tap

 

http://performancenissanparts.com/ca...oducts_id=2799

here is a link to the fuel T-tap that we offer. It is not recomended to cut that factory fuel line, even when we do installs on race cars here, we do not cut that line. Using this tap is much better and much more reliable.
the proper place to use this or tap into the fuel system is on the main pressure regulator, that is actually on the fuel rails, or just before the rails, under the plenum, in the middle of the heads.

 

Tony, how much would Performance charge for installing this fuel tap? I am currently tapped into the test port of the fuel rail.

 

is that the same part people were having problems with leaking fuel?

 

I believe this is the same SPX adapter that leaks. I’ve done more research into it and some people claim if you don’t purchase the connectors to the fuel line you will suffer lack of fuel, running you one the rich side. So I doubt I want to risk that. MySunset350Z, are you still spraying? More and more nitrous guys are moving into the turbo arena.

 

I don't think the charge to install the t-tap fitting would be too much. I would say about an hour to two at the most. but we are set with labor rates as is any dealership, and our discount to you forumites is $77 an hour isntead of $95.
plus the parts of course, which are not too expensive, and we have them listed on our site as well. It's an easy install if you want to do it on your own, you just have move thigns out of the way to get access to the main fuel pressure regulator on the fuel rail under the plenum

 

call up /Altered Atmospheres in Gathersberg MD and get their billet aluminum fuel tap block..DO NOT CUT that high pressure line , this aint no 69 NOVA here...

that's exactly what we sell, is an adapter, so that you don't have to cut the line.
any nissan tech will also tell you that it's not a good idea to cut that main line too...

 

That is a matter of opinion. I ordered the Altered Atmosphere fuel adapter from you guys and it is a great little piece. While waiting for it, I went ahead and cut the factory fuel line, "t" it off, and we checked the fuel pressure at that point. It was 51 PSI constant. It is also 51 PSI constant at the dampner.

I will say this. The Altered Atmosphere adapter is very clean looking and a really nice piece that I haven't heard of one person having a problem with. The only reason I haven't switched to it is because it didn't come with the longer bolts needed to mount it. I kinda expected to get the bolts with the adapter because the site said that that it requires the use the 4AN fitting in addition to the adapter itself, but didn't state that I would need to buy the bolts seperately. So until I get some bolts, I will just stick with the good old tap that is working perfectly fine.

 

Did you mean suffering lack of fuel, running you on the LEAN side? I have not run lean at all without the adapter hooked up. Like I said, I have one, but have not hooked it up. Things are running completely fine as it is right now.

 

My daddy always taught me the less connections to fail the better.So what you have effectively done is create 3 additional places for a potential fuel leak and fire..

 

Your daddy was a very smart man. Did he know that more people were leaking fuel with adapters than "t" taps on the 350 Z? Like I said earlier, I have not heard of any problems with the Altered Atmosphere fuel adapter what so ever, but the fact remains that more people have leaked fuel with fuel adapters in general than with the "t" in the fuel line.

Due to the fact that I know the AA adapter is going to work well, I have all intentions of tapping with it in the near future and using my current tap for the fuel pressure sender.

I do however appreciate your insight on my possible fuel leak and fire! I'll pass the word to all the guys with the leaky adapters.

 

The leaking you speak of was on the SPX adapters which were NEVER intended for permanent fuel flow usage.They are actually a Nissan service tool to do fuel pressure checks,but you probably knew that right..They did not come with spacers and most leaks were caused from when they were installed people chewed up the "O" rings, but you probably knew that also right..

The AAM fuel adapter is specifically designed to tap off the fuel supply at the regulator for a guage or fuel line.It does not require spacers and will not leak.You method of cutting and splicing a high pressure fuel line is primitave and down right GHETTO and will fail at some point so carry a fire extinguisher in the car..If your method is so safe then why do all the fast cars do it the right way??

 

I am beginning to wonder if I should have bought my AA Fuel Adapter from you instead of Performance Nissan. As memory serves me correctly, you wanted me to pay $100.00 for this part because you were the only one, or at least you thought you were, who had (2) of these in stock.

Instead, mrtomcat, another member of this board graciously pointed out to me that Performance Nissan had it and I got it for a lot cheaper. Now I am really starting to see how you feel about this whole matter.

If you are having a hard time selling these, as it seems, since you are continually posting about them on a thread where the original thread starter has already stated that he is NOT INTERESTED, then hit me up in a PM and I will buy them from you and sell them for you! But if you want me to pay $200.00 for (2) two of them because you think you have the only two in the nation, then good luck and keep pushing them on people.

Keep telling them about the fires they are going to have and pass on the knowledge of your daddy! If you do this enough times, some sucker will come along and buy them from you at the price you want.

The funny thing about this is that I don’t forget people who rub me wrong. After you posted your little comment about your daddy, I though I remembered you. Then I did a little research and discovered why that I do indeed remember you.

Seems here you are the only one with something negative to say on this poor guys thread.
https://my350z.com/forum/showthread....ht=10secapsttz
Here you come on to my thread and reveal that you have two in stock, but you almost act like your doing us a favor by giving us that info.

spdu4ia, if you need clearer pictures of the tap, I can get some high resolution ones for ya. MySunset350Z posted a picture and it is exactly the same as mine.

Just be AWARE that according to 10secapsttz, you need to carry a fire extinguisher if you choose to go this route, because it will leak and you will have a fire at some point in time.

Also, if you do decide to go the AA Fuel Adapter route, PTP Motorsports has them for $35.00 now.

If you buy it cheaper somewhere else though, you might **** of 10secapsttz, and he'll follow you around posting wise comments behind yours. Of course 10secapsttz, "you probably already knew that right?"

 

My SPX fuel tap has been working flawlessly for about a year now and I bought it used from another forum member. The only possible problem with the SPX adapter is that the ears that the bolts go through on the OEM fuel connector do not have any support under them with the SPX adapter so over-thightening "may" cause leaks.

 

you missed the entire point of my posting...If I were trying to sell something then why would I point him in the direction of Altered Atmosphere then??That sounds like a pretty crappy sales pitch doesnt it?"Hey I sell Nissans,Have you looked at the new Mustangs?" Pretty silly huh..
My point was that there are two ways to do things,The right way and YOUR way.Hey if your way is working fine for you then so be it,I personally would never want the liability of splicing into a customers "high pressure fuel line". It will eventually fail,period..The Guy was looking for advice and I was giving him my hard learned professional opinion,not selling him something. He asked for peoples opinions,unfortunately he will most likely listen to your advice to save a few bucks and be a casualty of internet mechanics..
You heard it from me,you heard it from Jeff@ performance and his Nissan techs,but you insist that your way is safe and reliable.If you think so then best of luck and thank you for the kind words pal..

 

i t-ed into the fuel line 2 summers ago and have not had any fuel issues. fuel pressure has always been at a steady 52psi, around 50psi at wot.

i originally had ordered the spx adapter and decided to t into the line while waiting over a month for the part to arrive. couldnt wait, dragstrip was calling.

yes, still running nitrous.
