Don't panic. ''Omaha Orange'' was a DuPont color name. They sold it to all the Big Three, GM, Fomoco, Mopar. A lot of municipalities uesd it for fleet vehicles. I think your Blazer looks fine. Wish my K/1500 Jimmy was Orange. I bought it because it had an SM465 4-speed and had 33x12.50x15 tires like my K/10 Suburban.

Among the fancy names Marketing Guys peppered sales brochures with, when trying to sell Orange-painted cars, were: Omaha Orange, Sunbolt, Tangerine, Tangiers, etc.
[Hugger Orange and Tomato Red have more red pigment in the mix.]

Among the paint colors I'm looking at for a 50 year repaint is Subaru Crosstrek Orange. [They only put it on Crosstreks!] I think it's a little lighter [more yellow] than GM RPO 516 Orange, but after 55~ years under the intense solar radiation of Cali and AZ, the Subaru shade matches mine.

Fuel Pumps is a separate issue. QC overseas is lax, and alot of the rubber diaphragms inside are not Gas-Ahol proof. Mechanical or electric?

You still have that shortbed frame? My wheelbase is 115''.
