What to Do First

Safe, general first steps. Truck down near Ocala or Wildwood? Call (352) 662-9996.

Safety First

Pull Over Safely

Get as far off the travel lanes as you safely can, or take the next exit if the truck can make it safely.
Turn on your hazard flashers right away.
Set out your three warning triangles as soon as you can, and within 10 minutes. On a divided road like I-75, federal rule 49 CFR 392.22 says one about 10 feet behind the truck on the traffic side, one about 100 feet back and one about 200 feet back.
Stay clear of traffic. If you are in danger, call 911. In Florida you can dial *FHP (*347) for the Highway Patrol.
Then call (352) 662-9996 with your exit or mile marker and what the truck is doing.

Next Steps

If You Have a Water In Fuel Light

If the water-in-fuel light comes on, find a safe place to stop soon. Water can damage fuel parts.
Many trucks have a fuel/water separator you can drain. Only do it if your manual shows how and you are in a safe spot.
If the truck is sputtering, losing power or won't start after fueling, tell the mechanic where and when you last fueled.
Keep your fuel receipt. It can help if the fuel was bad.

Questions

Frequently Asked Questions

Can I keep driving with the water-in-fuel light on?

It is safest to stop and deal with it soon. Check your truck maker's manual for what it says.

Can a mobile mechanic fix water in the fuel?

Often a mechanic can drain the separator and change fuel filters where the truck sits. If water reached the injectors or pump, it may need a shop.

What should I do first when my truck breaks down on the shoulder?

Turn on your hazard flashers and get as far off the travel lanes as you safely can. Federal rules (49 CFR 392.22) say to set out your warning triangles within 10 minutes. In Florida you can dial *FHP (*347) for help from the Highway Patrol. Then call us with your exit or mile marker.

Do you do the repairs yourselves?

No. Alligator Diesel connects your call with a local mobile diesel repair shop, and that shop does the work.
