Was the car parked on a hill with the butt up in the air? If so, the gas can siphon out of the tank. The post about the gas cap on and residual pressure wouldn't amount to very much gas pushing through.

Just dont lay your fuel line right back in place like i did. It was the perfect storm. it dripped right down the intake holes. Lay it off to the side, crack the gas cap too.

I used a length of rubber fuel line. One end over the feed line and the other end over the return line. Just pushed on.

Yes. Oil made it all the way out of the throttle body and I think the exhaust is full of fluid to as she is bellowing out smoke and I can hear a crackling in the exhaust like something is frying in there. There is oil all throughout the engine. I have been cleaning the throttle body and manifold all the time and it does have residue in it every time I clean it. It smokes less and less so I am hoping it just needs to burn off all the fluids that made to where they should not have been as I drained 12 quarts out of the engine. I have never done anything this stupid to one of my cars before, what a lesson this is.

I just ordered a set of Bosch III injectors. Looks like you install them first in the manifold. Then put the rail on the injectors. Good thing I found that out, as there was a video where the guy put the injectors in the rail first. But I guess that is because of the design II Bosch injectors with the clip. As I guess the III don't use the clip at the rail.
Does anyone clean out the rail, or flush it out before you put the new injectors in? I wouldn't mind cleaning it out, but don't want to take the rail apart either since it isn't leaking.

Yes, you just push the injectors into the manifold then set the rail down onto them. I lubed the orings with some petroleum jelly and once I had the rail hooked back up I hooked the battery up before I put the runners and plenum back on to check for leaks. Glad I did because the injector for #2 leaked just a little bit so I had to reset the fuel rail. Just turn the key to on to get the pump to pressure it up then let it sit. Beats finding out then if one is gonna do a little leaking than after you have put everything back together. I learned that after I put the BIIIs on my 89 formula with the L98. DOH!

My guess is there was just enough pressure still in the system to push out some fuel which then pulled more fuel like syphoning. It just started pulling it up. Bad luck though since he said he ran it until it died. I just hooked a fuel gauge to the valve and bled off the pressure until no more fuel came out of it.

Going to put Bosh III in my 95 tomorrow, installed a new fuel filter today, that gas never stop completely for me. Checked for leeks everything was fine and I did replace the old O rings they were there. pulled the FP fuse again started it till it died went to just crank it to relieve any left over pressure it starts again and dies. Did this three times and I gave up. Did this procedure for the filter and after the first time it worked. Whats up ? is it stilling pulling a little fuel to start and die.

I just installed some bosch IIIs a couple of weeks ago. I decided to leave the rail alone since it wasn't leaking and from what I could see looked clean. Runs better now but I did end up having to change out the IAC. I had removed the old one and tried cleaning it up since it was very dirty but the throttle body cleaner I used evidently mucked it up.

What I plan on doing is after I get the plenum and runners off. Is to turn the key to "on". And check to see if the rails are leaking. As if they are not, then I guess I won't tear the rails apart. I'll just save the o-rings I ordered with the injectors. Did you clean the rail out any? I know John mentioned cleaning the rail out, but I wouldn't want to damage the o-rings.
If the fuel lines that connect to the rail have o-rings. I may replace those while I have those off.
And what would be safe to use to clean out the inside of the plenum and runners? I've got some carb cleaner and break cleaner I could hose the inside with. But not sure if that would damage anything?

Once you remove the air sensor that is on the bottom of the plenum there is nothing in it or the runners to hurt. I used carb cleaner and throttle body cleaner and rinsed them out real good with water. Went after the top of the plenum with 120 then 200 grit sand paper and used a 150 grit sanding wheel flapper on my dremel. Used a green scrub ball on my drill to clean the runners real good. Finished them up with mothers aluminum polish.

Did you clean out the inside of the rail any? I figure dumping cleaning in it would probably mess something up if you don't take it all apart. I don't plan on taking the rail apart.
