Does anybody know the part number or where I can find some -6AN adapters to stock oem plastic fuel lines.

 

Check the Russel catalog or the Aeroquip catalog. Somebody makes them in both 3/8" (supply) and 5/16" (return) sizes.

OOOOOPPPPSSSS.. I just realized you are looking for something to fit the stock plastic lines.... I have never heard of anyone making those.

 

you would have to use an NPT barb fitting, then go to an NPT to AN adapter, then to -6AN. nothing is going to go directly from AN to plastic line

 

I found these two from summit racing:

and this

http://store.summitracing.com/partde...5&autoview=sku (return side)

or I found somebody selling something like this: http://www.ls1tech.com/forums/showthread.php?t=753434
