Rust inside my fuel rails??

[mystang94gt]

My car has been sitting for probably about 5 or 6 months while I got the money together to get it looked at since I didnt know what the problem with it not starting was. Well I towed it to ford and they changed the computer. This got the car to start but it ran like s*** and they said I might have 2 bad injectors. So I took it home and went to swap the injectors for a good set of 19#'s I had. When I got the rail off I realized it was filled with rust and grime and 6 or my 8 injectors were filled with it as well. So no wonder the car wasnt running right? Neway now I found a new rail and it should be here anyday. But my questions is how could this have happend? And how can I keep it from happening again? Someone told me it could be water in the tank. If I drain it completely and flush the fuel lines will this cure my problem? Do I need to replace the tank all together? Any help is appreciated.

Seeing that you live in cali sue the govenator for cali's special blend fuel that tore up your rail and injectors. you'll probably win like a million for mental anguish LOL! On a serious note though yeah it was probably due to moisture in the tank. As for flushing the tank and lines I dont know. Good luck

It's definitely a moisture problem. Switching to aluminum fuel rails would eliminate it too.

I would almost wonder if since it was sitting so long if the fuel evaporated (or settled) out of the rails and then the moist air in the rails allowed them to corrode.

Then when the fuel started pumping again it colledcted all the crap and pushed it into wherever it could collect (ie the injectors).

Just in case I would let the fuel pump clean out the lines themselves before putting on the new rails so it doesn't happen twice.

That's kinda what I was wondering too if it happened because of how long the car sat. I was going to replace the fuel filter and flush the lines with an air compressor before installing the new rails. I think I will start there and see what the fluid that comes out of them looks like and determine whether or not I need to take it any further. Hopefully I can leave the tank alone. I just dropped it a couple months ago for a new fuel pump when i thought that was the problem.

This is what I was going to do at first. Just switch to aluminum so they could never rust. But they are way too expensive for me right now. So I had to get some used ones off ebay. $40 is alot better than $500 right now.

I have a set of blue anodized UPR oversized rails I'll let go. It includes the fittings for connecting the rails together and a short piece of stainless hose in between the rails. PM me for details. I should have mentioned it earlier. Sorry! Also have an Aeromotive adjustable FPR if your interested.

 

[mystang94gt]

I have an aeromotive AFPR already and its one of the reason I didnt want to switch rails. I didnt think it fit aftermarket rails and I've only had it a few months. Plus the ones I bought are already on the way. Thanks though.

No problem brother

Change your fuel filter as well if you haven't done so. You may have gotten some bad gas or something,.

Good Point about the filter...

Maybe a good time to run some fuel system cleaner through as well?

WTF?!?! This has got me paranoid, my car has been sitting for about 4 months, I've started it probably 5-6 times, should I worry about this?

Oh yea, the BBK SSI comes with Anodized Aluminum Fuel Rails!! *hint* *hint*

As long as you run the car every couple/few weeks then you should be fine.

As I have 2 vehicles I make it a point to never let either sit for more than a week without driving to get everything up to temperature.

If you start your car every once and a while and let it run you should be fine. My problem was I couldnt start it for 6 months even if I wanted too.

Ok so the plan so far is to change the fuel filter and use the air compressor to flush the lines from the fuel filter to the engine compartment. Then install the new rails and injectors. Hopefully the lines themselves are ok.
