I decided to try one of these life hack rust removal remedies while my fuel tank closing plate was off.

The results were quite astounding. These were all rusted prior to a week long bath.

Cool.

Wonder if you heat the vinegar if it will work even better (faster).

Very cool Dave. I tried cider vinegar at the start of my restoration on a front caliper. It loosened the grime, but it also immediately took off the yellow chromate layer and left just the first clear zinc plating layer.

So, I would caution using acid if you are concerned about the plating. I didn't leave it in the acid long enough to determine if it would have removed the clear zinc layer, but I know it worked quickly on the yellow layer.

I'm going to give them a blast of clear coat for protection.

Oh good. I don't know it they will need a bath in bicarbonate soda and water to neutralize the ph before painting. I did that when I stripped my metal parts with muriatic acid as a prep before plating.

I use the natural white vinegar to clean up rusty tools. Just pour some into an old Tupperware container and put in as many wrenches/sockets/ screw drivers, etc. that will fit and let sit for a week or so. It's only $2 a gallon and will do the work of ospho, naval jelly or any other rust removing liquid. :race:

Dave,

Can you tell me what the dimensions are for those larger washers? My early vin doesn't have them.

Does your gas tank cover plate have the larger oval holes or the ones that are more like 8mm round?

It appears that I have the 8mm round holes with the exception of the aft 2:

The problem is that they protrude a bit on the top, which could lead to rubbing against the A/C hoses. I thought that adding that washer would fix the issue.

Hi Brandon,

I have the same setup, except the 8mm bolts ( aside from the aft 2) have both a flat washer and a lock washer.

They make the bolts more flush on the top side.

It's 8 MM inner and 30mm OD, and probably 2 mm thick. A close hardware store size is 5/16 ID x 1-1/4 OD.

If you have the plate with the small holes, they don't really need to be that big OD, so common 8mm flat washers will work as spacers. The factory washers are thick, i.e. 2mm or 1/16"

Good idea to keep the bolts flush with the frame, I've seen quite a few A/C hoses compromised by rubbing bolts that are too long.
