View Full Version : Fuel Rail Supply Line? LS2

03-11-13, 10:33 AM
Ok, what's this piece called circled in orange? Seems I have to cut the covers more to get a good fit and I'd like to replace this piece from a corvette... or get a custom.

Is it the fuel rail supply line? Any help with a part number, size, or if the one from the corvette part number will fit? Better to get a custom fit?

Anyone know where I can order or what pieces I need to order to make one or a few for people that may want one?

Need to know sizes of the connectors and lines... Steal branded would be nice. Any Tech guy know this??

hey - I bought a pre-fab 18 inch AN fuel line from SummitRacing or PegasusAutoRacing but could have made one as well.

here's the post with part numbers on the fuel rail to AN adapter: http://www.cadillacforums.com/forums/2004-2007-cadillac-cts-v-performance/242979-converting-6-fuel-line.html

you need
Russell part 640850 - http://www.summitracing.com/parts/RUS-640850/
Russel part 640940 - http://www.summitracing.com/parts/RUS-640940/
Russel part 658520 is a 24" line - too long, really - you could make your own - http://www.summitracing.com/parts/RUS-658520/

Found the parts, and they work flawlessly! I have enough tube to make one more if someone wants one. Or message me and I'll make one for ya with different colors. Now I gotta find the clutch line parts!
