replacing fuel tank skid plate

Planning on replacing the rusted out fuel tank skid plate in the the near future on my '90 YJ and see the rubber pad in-between tank and skid plate. Just thinking about the new OEM skid plate and would seem that a few drain holes might help keep moisture down by allowing the top side of skid plate to stay more dry. Maybe 6 or 8, 3/4" holes strategically placed. I don't see any problems with this but I could have missed something?

I don't think the holes could hurt as long as you put some rust preventative on the raw edges of the holes.
I think the biggest cause for rust is the pad that the factory puts between the tank and the skid plate. I've seen rubber pads and some kind of heavy tar paper used as pads. I think the pad is used to prevent friction between the poly tank and the metal skid plate. If the poly tank sat directly on the metal skid, and sand or gravel got between the two, the foreign material could worry a hole in the poly tank bottom.

Your jeep is 28 years old. It took almost all that time for the stock skid plate to rust out. Do you plan on having your current Jeep 28 years from now?

I'd simply put the new skid plate back (with a new pad if I could find one) and not worry about it.
If you cut the holes with a hole saw, file the raw edges of the holes smooth so that there isn't any nooks or crannies to hold water then prime and paint the raw edges.

If your Jeep has a 15 gallon metal tank, now is the perfect time (budget allowing) to install a 20 gallon poly tank.

Good Luck, L.M.

Yeah if it needs another skid plate in the year 2046 that's probably reasonable....

I wouldn't drill any holes..... if the skid plate ever does get drug on the ground they'll scoop up dirt or rocks

The rugged ridge replacement is enclosed on all 4 sides and already has drain holes...worth the money IMO....line it with thin poly instead of tar paper like OEM and it will probably still be on my jeep after I am dead and gone.
