I have diesel fuel in my motor oil the tank drains into the oil pan when sitting off

if the engine is a petrol engine , you drain the tank and refill with petrol, you may have to bleed the fuel rail but basically it will run a bit rough to start with until all the diesel is flushed from the system then it will settle down
if it is a diesel engine and it is not performing on the bio diesel mix, drain the tank and replace the filter and refill with regular diesel
it may be a bit rough until the system is flushed
If it runs good just use the tank then refill with regular diesel

my 135 fuel supply pump was leaking into the engine . I removed the pump pressured a line with air and found the leak at the seal

No idea of what your saying

If you put the wrong product in the motors
crankcase,drain it out & add the correct oil

If you put diesel fuel fuel in a gas tank,then you
have a big problem & will have to remove the
tank & clean it & change the fuel filter

Diesel Fuel in the motor oil will ruin the motor
after about 20 miles on the road from lack of
lubrication

I would guess you know all that I said before you came here

Try changing the fuel filter. If that does not help, have someone test the injector pump for pressure. Last would be a compression test on the cylinders. Drain oil and replace oil filter very soon.

What has happened is the diesel fuel is a lubricant and gasoline is a solvent. As gasoline is much thinner, it could wash down the cylinders and get into the oil pan thinning the oil and ruining the bearings. This would be the reason to test the pressure in the cylinders to find out if you lost compression with the rings in the cylinders.

Next, the injector pump for the diesel has seals and tolerances for inside components. Again, since gasoline is a solvent and not a lubricant, the internal parts could be worn out by not having diesel fuel to lubricate the injector pump parts.

If someone working at the fuel station made this mistake, all the costs should be paid by the station. This is something which could be taken to court if the station does not pay.

Hi. Here's the procedure on how to change the oil pan.

Things You'll Need:
Drain pan
Crescent wrench
New oil filter
Oil filter wrench
Socket wrench
Socket set
Razor knife
Putty knife
New oil pan
Oil pan gasket
6 qt. of oil
Clean towel

Draining the Oil
1. 1 Locate the oil pan directly underneath the engine. The oil pan will be held on to the bottom of the motor by 16 to 18 bolts. The drain plug is at the bottom of the pan.
   
2. 2 Loosen the drain plug with a crescent wrench. Allow all the oil to drain in to the pan. Tighten the drain plug when the oil is through draining.
   
3. 3 Unscrew the oil filter with an oil filter wrench. Place the oil filter with the waste oil.
   
4. 4 Rub new motor oil around the gasket of the new oil filter. Pour 1 qt. of oil in to the filter.
   
5. 5 Screw the filter to the filter housing with your hands. Do not wrench-tighten as this will strip the threads and make removal of the filter difficult.
   
Replacing the Oil Pan
6. 1 Locate all the bolts holding the oil pan in place. There will be 16 to 18 bolts.
   
7. 2 Unscrew all the bolts with a socket wrench. Lower the pan to the ground. If the pan is stubborn, tap it with a rubber mallet to loosen the seal from the gasket.
   
8. 3 Scrape clean all the gasket material around the bottom surface of the motor. This will ensure a tight seal with the new oil pan.
   
9. 4 Place the new gasket around the new oil pan. Raise the oil pan to the motor and screw in all the bolts. Do not tighten the bolts until all are threaded to the bottom of the motor.
   
10. 5 Tighten the bolts with a socket wrench. Ensure that all the bolts are tight.
    
Adding the New Motor Oil
11. 1 Open the hood to access the engine compartment. Unscrew the oil filler cap on top of the crankcase. Pull the engine oil dipstick from the tube. Wipe the dipstick clean with a fresh towel.
    
12. 2 Pour in 5 qt. of oil in to the engine crank case. Insert the dipstick back in to the tube and pull it back out. Check the oil level against the markings on the dipstick. Fill at 1/2 qt. intervals until the dipstick indicates "Full."
    
13. 3 Start the truck and allow it to run for five minutes. Allow the truck to sit for an additional five minutes to allow the oil to drain back to the oil pan.
    
14. 4 Check the oil level again. Fill if necessary, but do not overfill.
    

Try using high pressure air to blow out oil returns. The engine may have sludge build up due to foreign material sticking in oil drains from a 52 year old chevy. Love that engine. It was good in it's day! Good luck!

I think you mean that you have water in your diesel fuel. Open the valve behind the fuel/water separator and drain out some of the watery fuel into a pan (place pan under the car). If you have a lot of water in your fuel, you may need to have a professional drain your fuel tank, flush out the fuel system, and try to salvage the fuel for reuse. I hope this helps.

do not worry about draining it, pour about 6 to 8 ounces of engine oil in it, and top it up with fresh fuel, it will be fine. The only way to drain the tank is to remove it and turn it over.

should be located in the fuel line on top of the motor.
