Russell 640850 is called out as a -6AN to
LT1, LT4, LS1 rail connector. But I can't
make out whether it's for the Schrader,
or to braze up to the stock rack. Which is
what I want to do (AN fittings onto both
ends, stainless, brazed on).

Anbody familiar with these who knows?

 

I converted my 1996 Z-28 over to 6AN braided lines. I used some fittings from a company called Pure Choice Mmotorsports. They fit perfectly to the fuel rail and allow you to attach AN fittings. I think that they were about $60.00 a pair and I also used them on the hard lines at the bottom of the car. The project looked great and really cleaned up my engine bay. Check'em out!

 

Also, they do fit the LS1 cars!

 

Do you have their url?

I hope this helps

 

Would these work on the return hard line of the send unit? I send line is definately the same diameter as the fuel rail, but the return line appears to be slightly smaller than the send line.

 

Yep, those are the ones. I pulled some out, I still have 4 brand new ones and the package says that they are $34.95, I ordered so many at the time, I could not remember how much they were. They are part # 5800 and fit LT-1, LT-4 and LS-1. I used them on the hard lines on the bottom of the car also. On the bottom, I had use som fine sandpaper and then steel wool to get them to slide on easier.

 

I still have a picture of the Pure Choice Motorsports connectors.

 

would these also snap onto a fuel filter?

 

If it has the same type of connectors, yes. Just figure out what size they are and get the right size fitting.

 

TTT

Good info for adapting stock fuel lines with AN connectors...

 

Anyone know how much it would cost and where I would be able to purchase the stainless lines and fittings? I'd like to go dual intank walbro where the 2nd pump is activated via a hobbs switch under boost.

Basically looking for a cheaper alternative than Lonnie's dual tank which uses the stock lines for $599.
