Yesterday I was getting on the interstate. My engine fluttered then lost about 7 PSI boost and obviously lost some power. I let up and hit the throttle a couple of times and it picked up and went like nothing ever happened. When I got home the engine would not shut off with the key.
I pulled the shut down solenoid and found the little rubber plunger had a chunk missing on the end that seats down in the pump. I installed a new one and Im good to go.
It just kind of worries me as to where that piece of rubber went.
I have put about 80 miles on since it happened so I hope Im OK.

 

If you don't have any problems now, I wouldn't worry about it -- I would guess that rubber is floating around in very small pieces in your tank right now. It must have gone through the distributor pump, the delivery valves, and out to an injector, where it either got burned up in a cylinder (having passed through those fire nozzles you call injectors), or sent back to the tank in the return.

Luckily it shouldn't be abrasive at all, and is much softer than any of those components .

I wouldn't have bothered with a new plunger, though, I'm a big fan of the hand cable .

 

Good to hear it was just the o-ring. The rubber piece should not be a problem. I believe me and Bob talked about this very thing not too long ago and he had the same opinion.

 

Thanks for your input guys, I am thinking after about 200 miles now that I will be OK.

asilitch, you said (having passed through those fire nozzles you call injectors) Im not sure who your talking to, I dont call whats in my truck injectors, they are nozzles, everyone askes me why I call them nozzles, and I say "because they are nozzles"
it seems most on this sight call them injectors but not me.
Just setting the record straight

 

Oh No- is that like "it's not a motor, it's an engine?" Jim

 

frostie, that very same thing happened to me 2 weeks ago. Don't worry, it's gone.

 

Yup, me and Monty did kick this cat a bit... don't worry about it...and no the rubber isn't gonna go thru a nozzle tip.... we're talking really tiny holes here guys...well, you know what I mean..

PB..

 

Oh my -- I was just making a crack about your liking to pour the fuel into your engine through as large an orifice as possible.

But now that you all have me going: An engine is any complicated piece of machinery, and a motor is something that converts stored energy into mechanical power. Injectors have nozzles, but the nozzle is only the itty bitty part at the end with the holes, exclusive of the injector body and pop-off valve, etc.

 

OK, now that we have that all cleared up
I was quite sure that piece of rubber did not go through a nozzle. but I cant imagine where it is, It seems too big to go through a fuel return line too. OH well, it is gone, out of sight out of mind.

 

If only everything on our trucks worked that way!

I'm glad it didn't cause you any serious trouble.

 

So true, and thanks
