Common questions
How do I know it fits my truck?
This part is listed for 1947–1998 Chevy and GMC 3100, 3600, 3800, Blazer, C10, C1500 and others. The full year, make and model list is in the Truck Compatibility tab on this page. If your truck has been modified, or you are between two of the year ranges we list, send us the year, make and model and we will confirm the fit before you order rather than after.
How long before it ships?
It is a stock item and leaves our warehouse in 1-3 business days. Transit after that is typically 2-5 business days in the United States. Larger orders can arrive in more than one box on different days.
What if it is not right for the truck?
You have 30 days from delivery to return it by mail. Return shipping is on you, and the part needs to come back uninstalled and unmodified - once a panel has been trimmed or welded it cannot go back. Made-to-order items are final sale. The full terms are on our returns page.
Can I install this myself?
It is designed for a home install with ordinary hand tools, and the fitment notes on this page list anything that needs drilling, trimming or welding. Where an installation guide or video exists for the part it is linked in the Installation tab.

This is a perfect solution for me! The bed I currently have was butchered and among many atrocities, the gas door was welded / blocked, I have instaled a new piece of sheet metal instead, and with this piece now I have a smooth nice looking solution on how to re fill my tank. Thanks Ls FAB team.
Veryceasy to order part was correct and looks great. Great company
Thanks Allan! Appreciate your review and support!
The fill fits with little modification and looks great in the bed of my 49 chevy 3100 5 window
