mini clipie ring thingy

 

here you go denny. i am thinking this is what your are talking about..







btw, i have some of this stuff in boxes.. let me know if you need them..

also. if you need help this weekend. i can come up and help..

really.. and i am serious, i would learn a lot!

beers

 

thinking about how that works - it would be impossible for it to get into the fuel line unless it broke off during installation ..............

 

ouch Zen! what happened after your flame out? Did your insurance cover everything?

 

OK Guys...talking about fuel problem!
I discover something strange.
on idle, if I spray some brake cleaner near the fuel injectors, the car's RPM change (going up).

so I thought I had a leak...

But I gave it a try while my wife keeping the RPM near 4000... no change in the RPM...

what could that be ?

 

There is possibly less manifold vacuum when it is revving - but more likely it is a percentages thing. Either way, the thinners/hydrocarbons in the brake cleaner are getting into the intake someplace, so I'd say there was a vacuum leak.

Ran the car to work last Tuesday (150 miles roundtrip) and the Snow Performance control box worked fine after setting it work on Boost mode. In fact I think I like it better this way rather than on MAF mode. Anyway it was a blast to ride the car again however is back under covers till next time around.

BTW, Sorry to hear about OD and Zen misfortune. Hope things will shape for the better soon.

 

I followed a link from OD, to Ken Bell's "Boost a Pump" page.


I saw a paragraph that read that they had seen less fuel flow at night when the stereo and lights were on; suddenly my huge Long Term Trims made sense.

Anyone else have a lot of wattage on the stereo?
Anyone else have large LTT values? (above 15 all the way to 20?)

Would these two groups be the same people? LOL

My headlights dim at night when the bass hits, so I know my fuel system must take a hit too.

 

/\ way more likely that you just need to recalibrate your maf

 

damn Z--man glad YOU are ok--i was lucky--very lucky.
that little clip(dark red thing still on the line) swoope is showing is what fell out some kinda way. Pressure must have pushed it out?
Swoope--man you are welcome ANYTIME. I almost have her out now--just trans and ppf etc left --then yank her out. Then I will be motoring to mazmart next weds/thursday to pick up the rick-e one. Then will start putting her together. Come on up a week from friday if you like. It will be hot and dirty, but yep you do learn a lot spending time under the hood. Replacing an engine really isnt that hard--it is just work. Especially if you dont have a lift.
I have already seen some things i can do differant.

Much to happy surprise and amazement, yes.

 

Thanks,

But why when I spray on the vaccum box or hose, the RPM does not really change and on the other hand when I spray directly on the injectors or on the fuel line connection (the one left to the vaccum box), the RPM change a lot (in the idle) !

 

i believe ya--seems to me that our primary rail fuel injectors are not as secure as i would like them to be. You can easily turn them with 2 fingers.
Now the red injectors--the apv ones they have a different washer/gromment on them. It seems like it would sealer better? I may look in putting that type gromment on all my injectors.
Also--yall correct me if i am wrong---I seem to remember somewhere that there is a little plastic piece that fits under the bolts on the mail fuel rail? Is that right? AM I wrong?
If there is one then would that change the fitment angle?

After I got my fuel rails and lines off, i put them back together. I was amazed at the line movement allowed on the rail --it will pull back and forth. Some movement is expected--but i also noticed that the little fitting that came out on mine ---after moving the line back and both a little---it actually turned to a angle and you could see how easily it could come out! Sum bitch.
I notch the connector lock ring so that a plastic tie would fit AND on the connectors (2)that have those little spacers I placed a small Plastic tie around it. That seemed to cure it all.
These gas lines move around some with the fuel pressure being on and off.
Converting to ss would be a pita.

 

I have this thing about not liking fire!

 

OD - Injectors are supposed to rotate in the rail. That is normal. Can we rule out the red snap-on clip was not damaged or clipped on properly. These are very common parts in late model fuel injected cars. The only one I need to disconnect to install my blower is one blue on on the vapour / breather like from the fuel tank. I can undo it with one hand, and the joint comes apart, and slides back on then snaps into place when re-fitting. No dramas.

Cheers,
Hymee.

 

yep that was my 1st r/o--it was on right and had been on right for 2 wks at least.
it was just too loose.

hey,

i have a bunch more fuel line / clips and stuff coming.. my box plus more.. i am going to try to be up friday late afternoon.. i need to talk to paul about a couple of things while i am there if i can.

glad you are sticking with it..

also if you have any odd questions about the remove, and how the parts fit in the injector area. you might pm G3tR3DDY2GR3DDY. you have met him. he was the found the fuse guy at robleing road.. he has taken apart lots of rx8s.

beers

 

swoope that will be cool man--give me and the family a chance to practice some southern hospitality. I am touched dude--really. Thanks.You will have a good time. For a break maybe we will get ya on the lake with the boat and ski/tube some?
Paul is working on bench pressing 400--freak--but a good freak.
Replacing an engine teach's a lot.

Dam OD, you got me worried cuz I upgraded to the large pulley and injectors. We took apart manifold and looked at the fuel rail and lines. See pix. We tugged on the lines and could not duplicate your problem. Just wondering if you have the same (or lack there of) cage affair that Ray has in his hand. This part is missing from the other pix. Could this be the cause??????

 

That blue "cage" makes it nearly impossible for the outer red "clip" to slide up and off the fuel line without being pulled in the opposite direction first.
It is kinda like Chinese finger-cuffs.

 

Isn't that the little thing that the Mazda manual says to throw away and never use more than once? (buy a new one each time it is assembled)

 

there are 2 different types of connectors/locks. one type with the blue cage as shown and the other type is on the fuel line that connects the 2 fual rails. that line doesnt have the blue cage--it has a little spacer things (thanks Scott). see pic

https://www.rx8club.com/attachment.p...1&d=1250141618

if your clip/connector thing is a little loose and the gas line moves back and forth (it will) then this little spacer can dislodge. The larger pulley etc doesnt have anything to do with this.

I would not even trust a new one--zip tying all mine from now on.

 

If I made it sound like I was blaming the larger pulley, I apologize. I was strictly stating the fact that I too installed new injectors and was checking the hose connections. I saw your post and someones pix and thought something was missing. My car is different cuz that "cage" thing is part of all the connections.

I did not see any notation in the manual to replace them each time I used them but it could be there somewhere. I'll butt out, just thought I found something.

 

I am trying a new new lube in the blower; Royal Purple 75W-90 Full Synthetic gear lube.
I am hoping to quiet the blower whine with the big pulley.

Also, a question, has anyone used a sealant for the fuel injector to manifold seals?
I am thinking some of the black hi-temp RTV (very thin film) to "glue" the seals to the injectors, then the injectors to the intake manifold; not that worried about the fuel rail. (I want to make sure my boost stays inside.)

 

thought that was one of the attractions of a SC ?
