Are all of the factory fuel connections on the rail swaged barb fittings like they are on the return line? Has anybody ever reused these factory barbs and had a shop make up new lines with new swage fittings? I was considering SS braided lines but I didnt realize it required cutting into the factory lines. I like the factory way of hooking up and I'd like to avoid hacking my hard lines if possible.

they are just like the return line-swaged barb fittings, cut through the factory metal swaging and pry off, perfect barb fittings... I have made rubber lines for both my current and past 951's, surprised more don't do it....believe pressure line is 10mm

Yessir with a 3/8" hose barb, while the return is 8mm and takes a 5/16 hose. I figured it was as simple as that, I can't believe it took me this long to consider just having the lines reswaged. Do you know the size for the small jumper line on the rail? I assume it is 10m / 3/8 as well.

I've been using quality fuel line clamps instead of re-swaging, works perfect. I did a jumper delete on my current 951 but might re-do the jumper at some point and put back on-don't remember the size but think its same as pressure line from fenderwell...I'll snap a pic, no flaming for post HG/rebuild messiness, slapped it together at 1am to go play

If anyone wants, I can at some point pull the lines off the barbs to show what is under, but its a standard looking long 'shaft' barb..

Excellent, sharp pics! Thanks a bunch for posting those, I just have one more question for you. Maybe my car is a factory freak but it does not have those smooth flared ends on the hard lines. Rather, it has threaded male ends that attach to female barbed fittings, swaged on exactly like the other connections. This is for both the feed and return line. There are no fuel related pressure fittings anywhere on my car. Is that not normal? Also, when you did your damper delete did you just thread in a plug for the other unused bung? Any issue with the delete that make you want to put it back on?

the pressure side uses a barb fitting flared into a female 'nut' as factory, the fuel rail uses a male threaded fitting which you thread the nut/barb onto, then attach the new rubber lines and clamp down, the job really is as simple as using a die-grinder/dremel etc. to cut through the old swaged metal and pull off the old rubber line leaving the barb/female fitting as seen..might put damper back on due to fuel-resonance issues that might arise, might-but isn't an issue as it is

Turns out my hardlines are like those of a '90 car, which means mine are probably not the factory lines and must have been replaced at some point. That is apparently why the MY90 cars have different soft fuel line part numbers compared to 86-89 as well. By the way Rob, are you running stock fuel rail? I'm thinking I'm going to try deleting the damper as well and see how the car likes it. It only takes a second to reconnect it if need be anyway.

Interesting,
and yes my car is running the stock rail, I haven't noticed any difference in NVH or performance with the delete

kev951

You deleted your damper though?

993GT

correct, it's how I ran my last 951 for around 30,000kms, and have been running it that way on my current one for last ~2 weeks since finished rebuild...I might re-install it when I get a chance(amongst the other things I need to do) to rebuild the damper line just because it is 'correct', as it is I see no degradation in any way

jss

i ran with no dampner for 3 years

those mini t bolts are great I use them all the time. great seal with not chance to cut line

Anyone recalls the kit, that re-routed the fuel lines, so that they no longer go over the headers?

Just be really careful using hose clamps on the high pressure line. Inspect those often...

993GT

yup, I inspect them often just incase, clamp tension and old is awesome, I could probably pull the car around from them. FYI the clamps are made specifically for this job, also my dad is a hydraulics specialist/engineer and approved this
