Fuel System Cleaners?

Where's the pics???

 

Are the rubber parts trying to revert to crude oil? If so I have been seeing it in California for a few years. It's a result of the fuel additives we have had for a few years (oxygenates) in the rat urine they have been passing off as gasoline. I am not aware of the gas situation in Colorado but maybe you are just catching up with us on the left coast. It seems to be worst on cars that are driven little with low quantities of fuel left in tank. If anyone has a gray market F40 with the fuel bladders I would be very concerned.
PS, It has a nasty habit of clogging everything in the fuel system.

 

Dave: Swepco 503 is great stuff. It will not cause aforementioned problems.

Dave: email them to: bobafett@earth.he.net

I will put them up for you.

My pleasure. I'm amazed at what came out of there!!!

Is this more true of MTBE than ethanol? Are there other oxygenates in gasoline?

Anthing to do that would protect against this corrosion>

What's Swepco 503 supposed to do?

I can PM if this thread is too stale.

To Dave and David. It's not the first or worst I've seen. I should correct myself, it may not be the oxygenates, it may only be something added coincident with them. I never saw it before Ca. went to year round reformulated gas. As you may know many states have gone to different flavors of reformulation. In Ca. we have our own and Co. may have it's own too. All I know for sure is that our gas has a very different smell now and in the vehicles that I have seen the problem had the same things in common. #1 infrequent driving, #2 low fuel in tank, #3 very concentrated smell of the nature I have come to associate with the new gas. It may be that after sitting for some period with the very low level of fuel that some lighter elements of the fuel go to a vapor in all the air space in the tank leaving a concentrated, destructive formula the rubber is immersed in. Just my opinion based on observation.

 

Hi guys, I just had my fuel pumps replaced in my 97 550. Exact same problem. Totally broken down. Have you guys figured out whats causing the problem.

With the poor quality of some parts on Ferraris, it would not surprise me if the problem lies in the quality of components used in the fuel pump, rather than an issue with the gas or additives.

 

Dave Helms is working on it and I have not heard of any progress. Just for my own data base, how many miles on your car, do you drive it regularly or infrequently? And by any chance if infrequent do you park it very low on fuel or full? Thanks in advance for any info you can provide, I'm sure Dave will let us know when he has an update.

 

I just bought the car. It only had 8300 miles when I purchased the car. It was driven very little and sat for long periods based on the service records. Very dissapointing problem. I begs the question what else is deteriorating.

That supports the assertion that cars are better off being driven on a regular basis. For what it's worth this is a problem I have only witnessed on cars that sit for long periods. Also it is a problem, by my experience anyway that only affects the rubber in the tank. Sadly however, again in my experience the debris can sometimes make it past the filters and the consequences can be very costly. I hope Dave's investigation will give us some useful information that will lead to a way to deal with it. It is my opinion that the misguided efforts of enviornmentalism caused this and I don't believe the government will ever let us go back to real gasoline.
