I've searched and cant seem to find anything so if you wish to prove your clearly superior search powers, please link a thread that discusses this.

I bought a prelude that had been well kept, yet poorly treated after its engine decided to blow. The car was then left in a field for a while (two or three years?). I replaced the engine with a low mileage JDM H22. When I did that the engine wouldnt start. The problem was the fuel pump. It was dead. Naturally I drained the tank when I got the car as it had been sitting for quite some time. Long story short, the fuel tank appears to be slightly rusted inside. Its hard to tell how bad it is because I can only put about 2-3 gallons in at a time due to the fact that it is not yet 100% road worthy yet. Just wondering if anyone knows any sound ways to cleana tank that isnt going to cost me more than a hundred bucks. The clear answer would be to replace the tank completely but I do not have the money to do so at the moment. Any advice is greatly appreciated.

 

On an old Truck we restored a while back we siphened out the bad liquids/gas/water/shiznit... after that we put some medium size rocks in the take and with 2 people we shook the hell out of the take. Shaking the rocks around in the tank will break the rust off the metal, after that we dumped out the rocks and took it to a carwash were we used the high pressure rinse to break off any stubborn rust chips.. afterwords we turned the tank upside down and drained it really good, took it back to the house and hooked a water hose in it and let it fill up with water and with the steady flow of water it would lift the few remaining rust chips and flow them out of the take...this was a big help for us and we had no problems what so ever... If you do this make sure you let it dry a good time, best thing to do is to set it in the sun where it will kinda steam up and escape.

Also to be on the safe side you can get some additives that break water down...

Goodluck!

 

did you try this?

 

Havent tried anything as of yet. Trying to get a few ideas before i put it in motion but this one sounds like the best option at this point. Thanks for the advice.

*Edit*

Was just wondering if you still had the vehicle and if so if the rust problem came back up. Also how bad was it? I only put about 2-3 gallons of gas in my car at a time as I am still working on it and the rust that is there tends to clog the pump up and make a horrible sound. (my thoughts are that since its such a small amount of liquid it becomes contaminated faster than a full tank would).

 

I had the same problem, a radiator shop cleaned my tank for around fifty dollars,problem solved

 

no, i dont have the problem anymore

 

Sorry I was trying to respond to the person who originally started this thread.Was just throwing advice out there

 

Here's some fuel tank restoration products that might help you:

POR-15 products work great on surface rust, but of coarse if you have some heavy built up rust in there it'll be a big pain to take care of.

 

Thanks for the help guys. Probably going to do a combonation of things just to make sure the rust stays away. Still havent dropped the tank but Ill post up once the work is done
