It is a monumental job removing the gas tank on my 924. Is there a way to clean the inside of the tank without removing it from the car? It has been setting for a long time and I am sure there is sediment in the tank.
Any suggestions?

V2Rocket

removing the supply/return hoses, drain anything left in it, then stick a hose to the supply barb and flush it out the return barb?

What liquid do I use to flush it out?

V2Rocket

i imagine you should avoid water, though if you give it time to dry that might be ok...

anywhere around you sell E85 or straight ethanol? itll flush the tank out, won't damage anything but will clean the crap off the tank walls that 30 years of gasoline have left.

V2 Rocket,
I have a 924 with 944 front and rear fiberglass fenders. 5 lug rear wheels and front disk brakes. The wheels are 944. Strange. I bought it for $350.00 and thought it was a 944 but decided to restore it anyway.
I am having a little problem locating 924 new parts. Any suggestions?

Avoid water all together as "letting it dry" would just form rust. What you want to do is pull the low pressure in-tank pump (bottom of the tank) and sending unit (top of the tank, accessed through round rubber plug in the hatch under the carpet). That way you can see directly down into the tank and know exactly what you're dealing with. Any rust inside the tank should be removed with a rust remover such as ZEP brand available at Home Depot in a gallon sized jug. Let it sit in the tank for a good hour or so and you can cut it with water in about a 3 water to 1 ZEP ratio. For a rinse I like to use the old gas that I pull from the tank after I filter it through some old socks to remove the chunks, or old gas from lawnmowers/etc. After you use it as a rinse you can NOT run it through an engine! Run the gas down into the tank with a temporary plug, drain after a few minutes, filter it through socks, repeat. You don't want any of that rust remover (any brand) getting into the rest of the system as it will eat any aluminum parts including the fuel pumps (so don't use them as the temporary plug!!!).

You have a metal tank, so it would be best to remove it and clean it out well. A radiator shop can clean it out; around Phoenix area it cost ~$100.00. I just cleaned a tank for a Chrysler Lebaron Conv for my parents who let 3/4 tank of gas turn into a couple inches of nastiness. I used a pressure washer to lossen the crud, POR15 Marine clean (soak for 24 hrs) A steam cleaner which worked great after soaking, then finished with POR15 metal prep and the inside looks good. Cost ~$25 and a couple of actual hours.

This is something that I should have done about a year ago. I have a 85.5 NA with approx 80K miles. I drove the tank down to near empty and when I filled it up I thought it would be a good opportunity to throw in a bottle of Chevron FI Cleaner. Big mistake. After about 1 hour of driving the engine was coughing, sputtering and felt like it was running on 2 or 3 cylinders at times. Replaced the fuel filter. No difference. Replaced the fuel pump and the car ran flawlessly. Apparently I stirred up the ancient evil demons in the tank who then took vengence on the aformentioned components. OOPS!
