I got it figured out. I'm going to use 90 degree 5/16" compression fittings to male 1/4" npt, then a female 14/" npt to male -6AN.

So from the fittings on the feed side, -6 hose to Russell fuel filter  Fuelab fuel filter with 10 micron element and then directly to one side of the rail. From there, out the other end of the rail to aeromotive FPR. Then from the FPR bypass, return directly to the tank. More pics as I put it all together this weekend.

 

Got the downpipe done. Basically just cut up Trents old downpipe, added my turbo flange, extended it and added a Vibrant 18" resonator. I had one on my last downpipe and really liked the sound. Now I just need to plub the wastegate dump into the downpipe somewhere. Tricky part will be doing it in such a way that I can still get the downpipe in & out. It's a tight fit as it is..

Also finally got some OEM jewel headlights/corners to finish off the front end. :)

​You're going to use that compression fitting on the line out of the sender? Not sure I would trust that over time.  Hard 90º is also not ideal for unrestricted flow.

Hmmm. It's supposed to be good to over 200psi. Not really sure what else to do at this point, compression fitting was what was recommended at the local industrial fitting and hose shop.

I know the 90 isn't ideal. I could always go with a straight one and then use AN to make the bend.

OK! getting so sick of fittings! I ordered two of these... 5/16" compression fitting to -6AN. They will hold the 80-85psi no problem at all. Then i'll run a couple 120 degree fittings to get the lines back where they need to go. done and done.

If for whatever reason I start having fuel delivery probs then i'll revamp the pump assembly or something, but this should be good for now.

​​Those look better :)

 

It might, but idgaf at this point. :lol:

LOL. IMO the overall delivery length of the stock lines is more an issue than the sender. If you can mod the sender (as we can w/ the solid AWD sender cap), so much the better for uniformity's sake.

Pretty much had to drop the tank to get the old lines and stuff out. I just wish i had those fittings to get everything buttoned up and put back together.

Plumbing the wastegate dump back into the downpipe is going to be a PITA. Right now, i'm just going to run the screamer pipe. It will be a little bit before I start running the car hard anyway since I have to retune it. I have a U/J bend and bellows for the piping, but I might just get a shop to do something.. we'll see

Got the headlights in, mounted the FPR on the rail and started doing some of the fittings.

I also still haven't upgraded my injectors! I gotta get that sorted out.. I still have the 630s if I can't find the deal I want on the ID1000s

It's alive!

Let me back up a bit..

Got the fuel filter.. really nice piece. 10 micron paper filter. 10x better than the little Russell filter I bought previously which only had a 40 micron stainless disc

photo1_zps2fa72551.jpg

Got the compression to -6 fittings which also worked great

photo2_zpsc6b9dea1.jpg

Pulled all the stock lines out

photo3_zps44aeb2c8.jpg

Installed the new filter

photo4_zpse7e45dd4.jpg

S60R rail with -6 fittings welded on each end.. added the 98 dampener instead of getting the original feed hole welded shut..

Just going to run the 630s at the moment until I get things dialed in a bit better.

Dirty car back on the ground after months on jack stands!

photo1_zps907c9779.jpg

I set the base fuel pressure and fired it up.. the tune is WAY off, but it's got good cold start oil pressure, vacuum and AFRs are ok since I adjusted them

photo2_zps44307efc.jpg

 

Now the fucked up part...

I fired it up for the first time a few days ago.. checked for leaks etc ... all good but ran outta time and had to push it back into the garage.

Went out the next day and the garage smells like gas. Ok, so I check all the fittings.. they're all dry. No gas anywhere to be seen. I fire it back up to build pressure. Still no leaks. There are only 8 connections in the fuel system 2 at the tank, 2 at the filter, 2 at the rail and 2 at the regulator. I start sniffing around the engine bay and the fittings are all good but the lines themselves smell like fuel vapor.

I start googling and find all these posts on various car forums with people having the same issue.  This seems to be a common issue with many types of CPE hose. I used Russell ProClassic -6 nylon braided line.

It specifically says on their website http://russellperformance.com/mc/hose/proclassic.shtml

"For racers and performance enthusiasts who want high quality plumbing that's lighter and easier to assemble than traditional braided steel hose, Russell ProClassic hose is the perfect choice. It features a lightweight nylon fiber outer braid with a CPE inner liner, and a maximum pressure rating of 350 psi. It is capable of handling nearly every plumbing task on your car and is safe to use with fuel, oil, or antifreeze. "

Since I mounted the FPR right on the fuel rail and have lines going close to the motor, I do not feel confident driving the car.

It seems like the way to fix this is to use teflon (PTFE) hose or hardlines. The local supplier is looking into the issue and will probably let me return the hose as defective, but i'm not sure about the fittings. If I go PTFE, it uses a different type of fitting.

I'm going to call the local industrial hose shop and see what they recommend. If i'm pulling all the lines out and redoing eveything, then i'm doing it right so I never have to worry about it again.

Another one step forwad, two steps back.. seems to be a common occurance with this part of the build..

I used what is probably the cheapest AN hose and fittings on the market, and at the time of install I was really thinking that when all was said and done, it would smell like gas or leak. I haven't had a single problem with the fittings or the line and its been ~8 months since the install. However, the PTFE liner is thicker than other lines I have seen, so the ID is alighlty smaller.

BTW, is that paper filter E85 compatible? I thought your were planning on getting corny with this build.

So you're using PTFE hose?

The filter element says it's compatible with Gasoline and Diesel only. We don't have E85 up here, but the Chevron 94 pump I run probably contains a small percentage.

Correct, PTFE.

I opted for E85, that's why I went for a metal element.

just a note from my chemical engineering/rubber/plastics background...

cpe is, as you have found out, a cheap alternative to ptfe; however, does not offer the broad material compatibility like Teflon (ptfe). Fuel, as you know, is riddled with additives and we even administer our own additives in our tanks at time... Chlorinated polyethylene does not have the fluorine that Teflon does that creates tight, strong bonds resistant to VOCs. CPE will allow permeation of organics unlike Teflon, hence the fuel smell you are getting.

I never knew CPE was used for fuel lines on cars but in my world, I would never spec that material in for that application.

my two cents...
