Fuel line fittings

[project92]

Upper radiator hose = Gates #20893 (no idea of what the vehicle fitment is)

Combination = '02 F-body LS1 and 28" all metal radiator.

Lower hose from the '02 Silverado fit fine.

Per the S&P writeup on putting a 5.3 into a &#39;97 tahoe I used &#39;99 silverado upper and lower hoses. Just tried them out and they fit perfectly on my &#39;73 K5 with a 4-core 454 radiator.

640850 3/8" hard tube (LT1, LT4, LS1 Pressure Side) 1

640860 5/16" hard tube (LT1, LT4, LS1 Return Side) 1

These are Russell Part numbers not too expensive at like 16 bucks a piece at summit racing

Ref: upper hose.

Again I have a LS1 5.7 from an &#39;02 F-body, my water outlet comes straight out the front. By the looks of the &#39;02 Silverado 5.3 upper hose it looks like the water outlet may come out the top. I don&#39;t know, I just know it didn&#39;t work for me.

That&#39;s the hose I&#39;m using too, it just has a small kink in it. The best hose would probably be one of the convoluted copper hoses that alloys you to bend it however you want. They&#39;re about &#036;80 but worth every penny.
