I have a quick question for the group. I was working on my 84 SVO this weekend and had to remove the fuel rail to replace the Oil Pressure Sending Unit. When I pulled it back, the plastic fuel line that connects to the metal body lines broke right at the duckbill connector.
*Side Note* I have recently changed the SVO over from the factory nylon lines that used to run all the way back to the tank with a set of hard lines from a donor 92 LX. I also swapped the fuel rail out to match. SO I have got the bell shaped spring quick connect on the fuel rail end and the duckbill type connect on the hard line end.
While I am almost certain that I can replace these line with the same thing, I was exploring the option of replacing them with braided steel lines (no functional reason). I know switching over to braided lines can be pricey, but the problem I am running in to is how do I make them work with the duckbill connection? I see adapters all over the place for the spring connectors. I was wondering if anybody on here has done this swap before and what your method was for overcoming this hurdle?
Thanks for your help, guys!

AWESOME! Thank you so much and I apologize for not digging deep enough into the site to dig up your existing hard work. I do have some more questions. If I am thinking correctly, concerning the hard lines, the feed line on the SVO is a 5/16" line while the return line is a 1/4" line. According to the chart, the 1/4" line is equivalent to a 4 AN hose, while the fittings all seem to be designed for a 6 AN line. Is there any issues with using the larger hose between the rail and hard return lines? Also, what type/brand of braided line should I get for the fuel lines? (I am reading about issues with the rubber core lines being eaten away by the ethanol and additives that are currently in fuel) Should I use the same braided line that you make the oil feed line out of and if so, what brand is that? Are these hard to make myself if a buy the bulk hose and all of the fittings or should I try and buy a pre-made set (like this one www.americanmuscle.com/russell-fuel-line-kit-8793gt.html )and then purchase the needed adapters? Thanks again for the quick response! |

No issue.
You need a line that is rated for gasoline and alcohol/ethanol so it doesn't get effected by E10 or E85 over time. Braided line can be crimped (like we do our oil lines) or they have thread on fittings for people to make at home (which is what you'd need).
Those pre-made lines would be fine IF they are the right length for what you're doing.

It would probably be best to call Russell and ask. You shouldn't be able to use 2 different line sizes with one fitting though as there is no "adjustment" with the fittings. It's made for one size or the other, not both.

Sorry for my poor wording. I know that both of the adapters are for a -6 AN fittings. I was wanting to know if I could use the same STYLE fitting and I should have added the word "respectively" to the end of my first question. "Can I use the 641303 and 644113 adapter for both the 1/4" AND 5/16" line (respectively)" I know that I will have to get the adapter to match the size of the metal lines (the 641303 for the 1/4" and the 644113 or the 640863 for the 5/16"). I am more or less curious if I can use the same style for both lines or if I will have to specifically use the 640863 style for the 5/16" All that horrible grammar on my behalf to ask: "Can I use the Threaded Cap style for both lines or will I have to use the Push-On style for the 5/16" line?" www.russellperformance.com/mc/adapter-fittings/specialty-fuel-injected.shtmlThanks! |

I think you need the push on style (like stock) though I haven't messed with the Russell fittings to know for sure.

Thanks for all of the help. I wanted to reply back with my findings. I sourced my hose and fittings supplies from www.anfittingsdirect.com. I thought this was a good choice until I attempted to assemble my hoses yesterday. For enlightenment, here is the process I was following: www.anfittingsdirect.com/an-fittings/replacement-brake-lines-p-1253.html (Install instructions are near the bottom of the page) If I was truly a car guy and had a real work area/shop to do projects in, I most likely would have been successful. But, ALAS, I have to work where I can and doing a project like this in the kitchen table was not cutting it. SO, in true humility and defeat, I took my bulk -6 hose down to my local hose shop and in 15 minutes (and for $13 a fitting for SS fittings) they had my hoses crimped and ready to go. NOW, here is the kicker. Just this morning I discovered that I completely FAILED to do all of my research prior to purchasing my supplies and stumbled upon this video from Summit Racing: The two piece design of the Summit vs the three piece design (with the ferrule) of the ANFD fitting looks amazing. IF I had discovered the Summit fittings prior to putting my order in with ANFD and going down to the hose shop yesterday, I most likely would have been successful in making the lines on my own. In the future I most likely will purchase my braided hose from AFD (being that they sell the black PTFE hose and it is quite affordable) and my fittings from Summit. I do want to share the final product: drive.google.com/file/d/0B3vz-D9_LswXWldwb0lWanQ1dE0/view?usp=sharingdrive.google.com/file/d/0B3vz-D9_LswXcEpaRnl5cXpRZlU/view?usp=sharingdrive.google.com/file/d/0B3vz-D9_LswXWDF4aXZkUVdqbFk/view?usp=sharingdrive.google.com/file/d/0B3vz-D9_LswXVkJucU1VU3FkY28/view?usp=sharingThe final -6 AN hose length from end to end (including the fittings) was ~15.75" for both hoses. That is the length before the adapters are added. The adapters used for the pressure line are:Hose to hard line: Russell# 640860 (Blue) or 640863 (Black) Hose to fuel rail: Russell# 640900 (Blue) or 640903 (Black) The adapters used for the return line:Hose to hard line: Russell# 641300 (Blue) or 641303 (Black) Hose to fuel rail: Russell# 640870 (Blue) or 640873 (Black) I REALLY wanted to use the 644110 fitting type (that matches the return side) for the hose to hard line on the pressure side, however, the space between the two ribs on the nipple of the hard line prevented the screw-in retainer from fitting on the line. I fired the car up last night and everything seems to be holding just fine. Will let you know if I have any further troubles with it. |

Thanks for the info/pics.
Yeah, having to make the video 30 min long to show to to do PTFE line "the hard way" should scare some people away. We've got a crimper in the shop just like the one the hose shop used for yours. I just use a cutoff wheel mounted in a bench grinder. I don't use tape to hold the ends together either. I find if I cut it with the wheel and then put the fitting on within a minute or so, it's not needed. So without having to tape it, using a cutoff wheel, and the crimper. I can cut a line to length and clamp the two fittings on in less than 1 min.

I was under the impression that when using PTFE line you had to use PTFE fittings which must have the 3rd piece, the ferrule... the video shows assembly of standard hose, not PTFE
I could be wrong but that's why I am asking lol I literally going to be ordering my PTFE hose and fittings next week so I wanna make sure I get the right stuff

My crimp connectors for PTFE don't have a ferule, just an inner tube that goes inside the PTFE and the outer cover that gets crimped around the outside of the line. Not sure about the DIY threaded fittings.

Depends on what lines you're wanting to do, if you want to be able to remove the fittings in the future, and if you have a hose shop local to you.

I want to redo all the lines with 8an supply and return, I would like the fittings to be removable, and as far as I know there aren't any hose shops close.. Would the summit PTFE hose and fittings be ok to use or is there something better?
