Yeah, I believe the originals could develop a leak. Spraying high pressure gas into a hot engine bay is best avoided

As I recall we went with 1/2" (8an) feed and 3/8" (6an) return lines.

 

I'm keeping my stock fuel lines, have the tools and materials to make my own when I decide to upgrade.
Radium offers a nice filter and line kit with 8an feed. You need to go to their FD surge tank setup to see/order it. They also have a variety of FPD solutions that can be adapted to other rails.

 

Yeah, but it's the whole kit... seems excessive and I don't really (think) I need it all! Only planning to run 4x ID1050 which hardly needs -8AN lines.

So now it's between the full Radium set up with tank, lines, and rails, or just rails and a simple pump and wiring upgrade. (And maybe a garage alpha tank baffle.) That's about a $1000 savings between the two...

 

my current setup used with the twins at 18psi is a Walbro 400, 850/1300 injectors and a Hyperion (garage alpha) baffle, stock lines and filter. I'm upgrading to single turbo with a rewired Walbro 525 and 1050x/2600x injectors, still keeping the stock lines as they are enough for the majority of uses, that's why I'm keeping them and my new setup will be capable of over 500 whp maybe 600.

I suggested the radium fuel line setup in case you wanted to go that route. You can order just the filter+feed line and heat sink setup without the whole surge kit, just deselect the surge and select the feed line alone. I do like the filter setup though, I'm actually thinking about it...

 

Can you tell if it's possible to upgrade to their filter, but keep the stock hard lines? That would be a nice alternative...

 

I was looking at this and thinking the same thing. It should be possible, I think all you'd need really is to put some AN to Barb fittings onto the filter's existing AN input and output lines. Then you'd be able to use normal fuel hose (possibly even the existing fuel hose if you can route it properly?) and retain the stock hardlines. I also imagine that if you send them a quick email they'd be happy to confirm if that's the case. My dealings with Radium have always been pleasant in the past. They're good folks.

 

they do sell the parts individually, I don't know about the subframe heatsink/filter mount though but as XanderCage said, call or shoot them an email, they're good.

 

back to the fuel temp sensor for a second.
I just realized that the Radium rails each (prim/second) have a provision for either a FPD or a temp sensor. Which rail should the FPD go on, and which should the temp sensor go on? Is there a difference? Or do they each need a FPD?? Since there seems to be a provision off the FPR for a temp sensor... tho I kind of doubt the original harness will reach the FPR location? (and it may not fit under the radium primary rail, either, based on photos...)
So many options...

Thanks!!

 

where SHOULD it be? I can't tell you. What I'm doing is FPD on the secondary (using CJM) and temp sensor on the primary.
From what I've read, very large secondaries are the ones than can cause fuel pulsation so it makes sense to install the FPD closest to them but in reality the rails are so close together and fuel is incompressible so anywhere on the feed line or rails in theory should work.

 

Thanks again -- I emailed them, but they couldn't/didn't tell me which line I needed to run between the primary and secondary rails.

Anyone here able to help? I assume it's something like a very short 90* -8AN ORB to 90* -8AN ORB swivel or something like that?? Their shortest option is like a 6" straight -8AN to straight -8AN but not sure that will work....
