Ill go check mine right now for the threads on the fuel line for you.

Im almost positive 99 is variable effort which means more expensive

Are the o-rings for the top and bottom of the injectors the same size or are they different sizes? I need the ones on the end that pushes into the LIM. Also I need one clip that holds the injector to the rail. Does anyone have any extra orings or clips?

I also need the oring that goes on the end of the fuel line. I pressurized the system and it leaked from the fuel line with no oring, and the injector without the clip with a distorted oring.



I have a idea and im wondering if this will work. If I put a peice of piping that would fit in the hole where the spout on the P/S pump was and then slide the old spout over that then connected the rubber hose and clamped it would this work?

Have you taken your tensioner pulley off? If so how difficult is it? I didn't mess with any of the bolts that hold the pulley brakets onto the engine so i figure those should be alright.

I took the tensioner pulley and that entire bracket off to get to the lower rear valve bolt thats hard to get to..

The tensioner comes off by just unbolting the one bolt on it.


Eh do you have any extra o-rings for the fuel injectors or fuel rail....

The o-rings are real cheap and easy from Autozone. Make sure that you lube them up using oil before inserting them.

Well dang, I guess I gave up too soon... the high reving really scared me though... I'll post an update tomorrow and tell ya'll what happened. If it was a mistake with the LIM then I can at least warn others.

Noises in my car scare me too. But i'm the type to rather go in and try to find the problem by reading on here or looking myself then fixing it. If i break something along the way, whatever, live and learn.

I've never taken my car to a shop once with exception of getting new tires and i had a front bumper painted but that doesn't count as the car.

The mechanic's profession is not just to fix your car, it's to get as much money out of you that they can...otherwise they wouldn't be in buisiness.

The pricing is to satisfy them being the ones getting their hands dirty.

They have them in a package or you have to ask at a parts counter?

The o-ring for the fuel rails and injectors are different sizes. I can bring one of the injector o-rings to show or find what I need at the store, but the fuel rail o-rings I lost so I have nothing to show to match them up. Is there a part number for them?

[gectek]

they will come in a set, maybe felpro, but they have an injector o ring set for $26 last time i was lookin at it. and the other o ring i think youll have to go dealer on that one or a local hardware store or bearing place

[alerored04]

i just posted a link to the thread where the numbers for the o rings are at. Ill just go get it for you.

17113034 is the gm number for both the feed line o ring and the one for the fpr on the return side.

So i have to spend $22 for one injector o-ring....thats BS!

Doesn't anyone have any laying around?

[gectek]

hardware store

[alerored04]

which o ring from the injector is it? I have a few of the ones between the injector and the rail laying around. I have none of the seals between the rail and the intake though. If that is the one you need pm me your address. Ill send it out tomorrow.

They are the same size for both sides of the injector, i checked. but either way i need the one thats rail to injector anyways...

I just went to Autozone for mine when I did my LIM gasket change, asked to look at their o-rings that were gas friendly, and picked out the sizes I needed... worked perfectly, and only a few cents each. They usually have a tray full of different sizes to pick from. Ask the guy behind the counter.

[gectek]

yah they even have entire kits that have over 100 o rings in diff sizes for a few bucks, well worth the money

Yea well, the fuel injector o-rings I can actually bring in to match it up...but both fuel rail o-rings I lost so I don't have anything to compare it to...

is there sizes for those two or should I just buy a huge assortment and hope for the best.

[gectek]

and assorted piece set will have the size you need, also in the "help" section they will have a little package of assorted o rings that you could use also

Do you have a part number or like anything to say to get the exact package you got?

These are also fuel resistant correct?

The Oring that goes where the fuel line connects to the FPR I didn't even see what it looked like before I lost it, is that one bigger then the one that goes where the fuel feed line meets the fuel rail?

[BHermis]

I found an oring that was pretty close to the one i ripped on the feed line and then I added thread sealer to the threads. There are no leaks so far.

yea went to ace hardware and got orings...fixed everything up no leaks.

Now to figure out what to do about the power steering pump.

Supposedly you can swap just the reservoir? But I dunno if you can with the pulley still on?

I might just go to a junkyard and bring tools to take one off another car and ask if I do it myself will they give me a good price.

[gectek]

power steering pulley puller can be rented to take the pulley off the old pump
