You need to remove this right away. There is a small petcock on the frame or possibly at the spring hanger to siphon the water out with. Simply attach a hose to it and open the valve and siphon the water out until you get pure diesel fuel. Then replace the primary filter on the firewall. It helps to fill it before you reinstall the new filter. Drain the filter into a bucket and check for water in it. If there is you will also have to change the secondary filter on the engine. Then prime the system to bleed the air out. If you get a lot of water you may need to consider dropping the tank and cleaning it as well. On 1983 and newer trucks the light will come on with as little as a quart of water, on older trucks it doesn't come on until there is a gallon.
You may want to look into picking up a copy of Haynes Diesel Engine Repair Manual, part #10330. For $20 it has excellent help and advice on this engine. Hope this helps.
You can get the original GM dealer service manual from faxonautoliterature.com. It will have everything includung wiring diagrams in it. I've used them before and had excellent service.
If you are just looking for some help with your engine then Haynes has a Diesel Engine Repair Manual, part #10330 that is excellent for the 6.2 diesel. It's about $20 and covers the 6.2 and the 6.5. It includes a lot of tips that aren't in the GM book, especially up grades to some systems.
Hope this helps.
I think that you can buy another car for what it would take to do that conversion.
Lets' see off the top of my head.
carburator
manifold
new heads to accept spark plugs?
new body control module
new engine control module
then keep in mind that even with all the above it still might not work because you may need proprietary parts only made for a gas engine, and you have a diesel. An engine swap may be doable but I ahve never heard of it working out in the end.
