Fuel Hose/fittings suggestions
 

I just received my Rick's stainless tank, dual CTSV pumps, with the Vaporworx system and it looks amazing! Now it's time to do the install and I can't figure out which fuel hose and fittings I should use. Does anyone have a suggestion as to which? In similar posts it looks like Aeroquip and Earl's both seem to be working well. If anyone's made a similar install and could give me a recommendation on which hose, what length, and what fittings worked well I'd greatly appreciate it!

I used the XRP XR-31 hose based on Best of Show's recommendation. I used a short piece from the fuel tank to a hard line and from the hard line at the firewall to the engine.

I just double checked the name and I see a disclaimer in the XRP catalog about the best hose for all fuel types being their PTFE lined HS-79 hose.

In 2 plus year and over 9k miles I havne't had a problem with my XR-31 hose and it is super easy to assemble.

For the connection at the fuel rail and the fuel pump I used the russel AN fitting with screw on retainer rather than the plastic retainer (like this: http://www.speedwaymotors.com/LS1-LT...e-UaArj28P8HAQ)

I just got finished with my fuel system. Very similar as I too have ricks tank with twin CTS-V pumps.

I used the following:

• Russell EFI Adapter Fitting -6AN Male to 3/8" quick disconnect (PN 644123).
• One side had a 90deg fitting other was straight
• Fragola PTFE (Series 6000) -6AN black line
• Fore Innovations Billet Y-block (2x -6AN to 1x -10AN)
• Fragola PTFE (Series 6000) -10AN from Y block to Filter
• Fore Innovations Inline filter (stainless mesh internal)
• Fragola PTFE (Series 6000) -10AN from Filter to the Rail
• Fragola -10AN to -8ORB adapter
• Holley rails
• Fragola PTFE (Series 6000) -8AN from one rail to another (each having -8ORB to -8AN adapter)
• Dead head against the drivers side rear of the fuel rail in a fitting modified with a 3/8" port for fuel pressure sensor.

I can go in more details or get pictures if you'd like some.

Also of note, it adds up fast on fittings etc. I'd say with all the PTFE lines I'm doing, and the fittings I've purchased, I'm probably $800-1000 easy in JUST the fuel lines. That's with middle of the road PTFE. I saw some that was more than 2x the cost of mine /ft!!

Use PTFE hose wherever you need "flex" if you don't like fuel smell in your garage.

Yes it's slightly harder to put together because of the tight tolerances. If you don't have the tools -- see if your local hydraulic hose shop will do it for you. Just use tape and mark where you need it cut and a line to index the fitting if that's what you need.

Many of the hoses out there allow the "gas smell" thru the hose... which has a lot to do with todays fuel blends.

Agree on that fully. Friend swapped to same hose I have and said fuel smell is 100% gone in his garage.

Ptfe lines are a bit of a pain to work with but not overly complex. Had zero experience before starting and got the hang of it quickly.

Thanks guys! Where'd you locate the filter and Y block Will?

Y block is in the DSE shock channel in back and filter is basically right under rear passenger feet. Just behind the rear drain plug.

we use 1/2 fuel stainless steel fuel line and flex lines from the hardline to the tank and engine. Both ends have a T off of them
