how to deal with electrolosys?

TIRED6 · 14-05-2006, 07:42 PM

Hey,

I just pulled the carb of my 78' F100 to check it out due to poor running. I found that the entire fuel bowl was covered with a coat of sh1t about 3mm thick

: . I have cleaned it in diesel, fuel, thinners, degreaser and flat coke. All i have left now is the fiddly stuff that is fairly grown on it. Is there anyway to remove this as it still affects my truck?

Cheers,

so what actually is this coating i`know electrolysis is common in diesels i have one in the driveway, the electrolysis ate thru one of the liners, i have heard of trucks having this problem in other forms cracks in chassis, body work etc, which can be fixed i believe with an electronic device, as far the the engines go usually diesels run an additive in their coolant which is supposed to be a preventative (alfaloc or alfloc cant remember correct spelling ), i think electrolysis is static electricity basicly, i pulled the liner out of my detroit deisel and it looked like wood borers had been eating the liners of the engine, just wondering what sort of fuel are you running???

i run on premium, or a ulp/avgas mixture. But this coating is from when the truck sat before i purchased it. It sat for 3 yrs with no fuel in the carby.

Get the wire brush out get the tooth brush out...and some CLR or maybe sodybic and scrub the crap out of it.

I take it the Carb is made of aluminium. If so, go to the local car shop and buy some Alloy wheel cleaner.. It works a treat. Mothers is the best. Don't by the cheapie one, they are practicaly all water and don't work anywhere near as well. Mothers Cost $19..

sounds like a plan, try carb cleaner as well better than thinners i think.

Buy a small container of "sulphuric acid" apply with a cotton bud, leave it on for thirty seconds, rinse if it has done the job good, if not repeat the process until all the gunk has gone dont wipe it on you want the area wet, you will know if it working if the area foams and bubbles, keep what you have left to clean up any rust you may want to remove on other items.

Electrolysis from what I know involves the passing of a current through an ionic solution... Don't think you'd get that occuring in a fuel bowl...

Dissimilar metals cause it,We install a sacrificial annode on water mains to stop it, try using copper valleys over aluminium gutters, they wont last long,if you use a small synthetic spacer between carb and manifold it will stop.

Ah, Year 10 Chemistry. Turns out it may have been useful after all.

Oops.
