Did the fuel rail recall include the 1994 model cadillacs? I'm asking because just about every gas station where I live is going to be putting a mixture of 15% ethanol in their gas tanks in the very near future. This is making me nervous because I don't have the time right now to change out my fuel system to adapt to the more corrosive fuel, and I don't have the money to pay another shop to do it. I will wait for the parts to break before replacing them, but I don't want my engine to catch fire because of a fuel rail leak, so I would rather have a steal one on there beforehand.

Any thoughts or suggestions would be greatly apreciated.

No, it was '95 - '97 only.

15%! There goes more fuel milage. Where do you live.?

Where do you live.?

Way out in the middle of the pacific... Hawaii if that didn't give it away.

Another question then: Are there any steal fuel rails available for the 94?

No, do not think so. No need for them though, as the fuel rail is enclosed inside the intake manifold on the '93/'94. Should it leak, there is no chance of a fire.

OK, thank you Ranger. I just wish I had something that's not made of rubber to change into after they wear out. Ethanol is a solvent, so it eats away at rubber. I'm sure it wouldn't corrode too fast though... Ah well...

The fuel rails are not rubber. They are some type of nylon or plastic composit.

The ones on my car (1997) are metal. Stainless steel from the look of them.

I should think 1994s are metal too of some sort.

Uhh... have had 10% ethanol here for 10 years now. The ethanol will clean the entire system and possibly disloge junk thats been there due to regular gas being used. Its common practice to always use ethanol due to its cleaning capabilities.

Definetally change the fuel filter about once every week during the first month.

I have seen no decrease or increase in mpg using ethanol fuel in all three caddies ive owned.

Yes, our premium here is ethanol.

I have seen on snowmobiles a switch for ethanol that advances the timeing a bit. So im assuming it produces a higher octane or the ability of a higher octane.

There was a fuel rail recall for the '95 - '97 last year in which the nylon rails were change to stainless steel. Yours was obviously done.

I was going to say mine are nylon still...I called the dealer last week to price out a replacement, nylon is no longer availiable.

If yours are still nylon, get it in for the replacement. It is free.
OOPS. Your in Canada. I am not sure if those are included.

Are you sure they're nylon? It looks like rubber hoses to me, going from injector to injector...

mikeay, see if you can harass your dealer into replacing your nylon rail with a SS one. It's under recall in the US, so if they're non-douchebags they'll probably do it.

As for ethanol, it does have a higher antiknock (octane) rating than gasoline. It will affect mileage as well - with 15% ethanol it shouldn't be TOO noticible, not more than a couple mpg.

As far as 93-94 intake manifolds/fuel rails are concerned, they're not under recall. They probably should be, because a leak can cause the manifold to literally explode, but fortunately that's fairly uncommon.

Found this, I will make some calls and post back.

Make : CADILLAC
Model : SEVILLE
Year : 1996
Manufacturer : GENERAL MOTORS CORP.
NHTSA CAMPAIGN ID Number : 04V110000

Summary:
http://www-odi.nhtsa.dot.gov/images/spacer.gif SOME PASSENGER VEHICLES EQUIPPED WITH 4.0L V8 ENGINES HAVE A CONDITION IN WHICH THE NYLON TUBING USED IN THE FUEL RAIL CONSTRUCTION MAY DEGRADE AND CRACK. ADDITIONALLY, THE 1995 MODEL YEAR USES A UNIQUE UNDERHOOD FUEL RETURN LINE THAT MAY CRACK. CRACKING OF THE FUEL RAIL OR RETURN LINE TUBING CAN RESULT IN A FUEL LEAK INTO THE ENGINE COMPARTMENT. Consequence:
http://www-odi.nhtsa.dot.gov/images/spacer.gif FUEL LEAKAGE, IN THE PRESENCE OF AN IGNITION SOURCE, COULD RESULT IN A FIRE.

Remedy:
http://www-odi.nhtsa.dot.gov/images/spacer.gif DEALERS WILL INSPECT AND, IF NECESSARY, REPLACE THE ENGINE FUEL RAIL WITH A NEW STAINLESS STEEL FUEL RAIL. DEALERS WILL ALSO INSTALL A REVISED CHASSIS FUEL RETURN LINE. THE RECALL BEGAN ON JUNE 2, 2004, FOR 1996-1997 OLDSMOBILE AURORA VEHICLES. OWNERS OF 1995 CADILLACS AND 1996-1997 OLDSMOBILE AURORA WERE SENT LETTERS ON AUGUST 6, 2004. ADDITIONAL LETTERS TO OWNERS WILL BE FORTHCOMING. OWNERS SHOULD CONTACT OLDSMOBILE AT 1-800-630-6537.

GM Canada said there are no outstanding recalls for my car using my VIN#.

Are you sure they're nylon? It looks like rubber hoses to me, going from injector to injector...
They are definately not rubber. They should be a shiny, hard, black nylon running from injector to injector. If infact they are rubber, somone had a leak and jury rigged a fix. Replace it.

One more question: Does anyone know if the 1995-96 models' intake manifold and fuel rail would fit on my 94?

I'll take another look at them to see.

No.

No.


Aww, Okay then...


Thanks for all the replies. :)

No.

They were closing the computer lab at college so I didn't have a chance to finish my post.

What modifications would need to be made in order to fit a 1995 intake manifold onto a 94 northstar? (I'm a firm believer that anything is possibe, its just the difficulty of the matter) Are the bolt patterns different? I'm a fairly good fabricator (well i like to think that anyway :) ). I know that the FPR would end up outside the manifold, so it would need a vacuum hose to it... But what else would need to be done?

Obviously you would need a new fuel rail. I seem to recall that '95 is when they switched from MAP to MAF sensor. That would tell me you might need a new TB and MAF sensor and probably a PCM. That in itself might open another can of worms. Other than that, I don't know if it can or should be done. Why do you want to do this?

I heard that the redesigned intake manifold did a better job with the air/fuel mixture causing it to be a little more powerful with less MPG, And i figured that if I was going to end up changing my fuel rail and digging around in there that it may just be something to go for.

Hmmm, I wonder if I could get around changing the TB... maybe move the MAP sensor over and attach it to the air duct just before the TB, or even just run a vacuum hose to it... I would rather not change computer modules... I'm probably not actually going to do it but it would be nice to know that I could...

No MAF on my 95. The change from the speed density system to MAF happened for MY96.

I don't think it would take much to get a 95 manifold to work on a 93-94 engine. I wouldn't try a 96+ though...
