The did. it with the manifold on. I think my back still hurts from it. It’s doable but your way is definitely less painful :)

Mason_paul 01-05-2021 05:30 PM

I did it. Stupid autocorrect.

Also, thanks for all the kind words everyone.

Where do the lines from my NOS bottle go???

myamoto1 05-17-2021 07:51 PM

Sadly, it's taken me almost a year to get around to installing my lines from Paul. I've gotten the pressure regs out and just fitted up the "j" line under the left regulator and it looks pinched compared to some other pics and the factory line. Should I leave it as it or cut 1/2" (?) off and try to reduce some of the pinch? Here's what I'm working with:

Hi Josh, you may indeed benefit from a 1/2” reduction. It can be cut with a cutoff wheel or a hacksaw. I’d put a paper towel inside to reduce contamination and give it a good shot with compressed air afterwards…or just rinse it out with water and dry it off before reinstalling.

Good luck!
Paul

Thanks for the feedback Paul! Your kit is top notch. Only thing you need to do to improve it is include some fairy dust that'll allow you to shrink your hands and give you the ability to see through the intake :D

Mason_paul 05-18-2021 06:38 AM

Ha! I’ll get right on it ;)

Thanks!
Paul

The rubber diaphragm in that fuel regulator is just as old as the fuel lines.:eek:
When the diaphragm fails your plenum will explode on start up.:eek:
The Porsche fuel regulators are NLA.:rolleyes:
I installed an adjustable fuel pressure regulator that I set with a pressure gauge set up and set the pressure@ 2 PSI for as good a throttle response possible

Ted - Good point on the regulator. What regulator did you replace it with and were you able to use the existing mounting bracket (attached in above pics) for then new regulator? Also assume you meant 2 bar?

I'm fighting dropping the engine to minimize the "while you're in there" syndrome, but it's still creeping in...

This product worked well for me and has the desired adjustability

I installed an inline fuel pressure gauge set up, pulled the spark plug coil wires and cranked away to allow static pressure setting. This was done with plenums removed or you can't get @ adjusting screw when assembled

With all fuel system work, realize the system is high pressure and keep a fire extinguisher present.

Cut about 1/2" off and the bend looks much better.

NOW you tell me - hahaha. Wish I had thought of that! For future reference, where did you get that?

myamoto1 05-20-2021 07:08 AM

Just wanted to let you know the impossible is possible...

BLUF - this took me about 45minutes to pull as a single line. Now, I've spent 4x that trying to figure out where and how brackets are attached, etc..

The key is the bracket in the back of the engine that holds the hardline, soft fuel line and wiring loom. It's impossible to remove the 4mm bolt that faces the front of the car, holding the plastic part of the bracket, that would "release" the hardline. Impossible, until you free up the bracket and rotate it.

You'll want this handy: http://forums.pelicanparts.com/uploa...1621524244.jpg

This is bracket you are seeking:

You'll want a 13mm socket on a long extension to reach down to the stud, holding the entire bracket in place. You can see the nut in this pic:
http://forums.pelicanparts.com/uploa...1621524244.jpg

I used an extendable magnetic "wand" to grab the nut and washer, once they were off. I also used this same technique to put them back in place. I found it easiest to route the wand under the intake.

Sorry I don't have pics of this next part, but once the nut is removed, you can spin the metal part of the bracket (plastic portion will stay in original orientation). This should loosen it up just enough to spin the entire assembly, so the 4mm allen bolt is now facing up. Now grab that 4mm allen you had on standby and release the hounds! Or just unscrew the bolt:

Now you get to play Jenga and Tetris with your fuel line. I found that if I took the right side of the line, folded it towards the center of the engine, I could pull it up and out to freedom. Note, you might need to loosen some of the clamps on the idle-speed adjuster to spin the bolts out of the way. From there, it's just a matter of pull a little this way, push it over that way and you can slowly work the line out. I did have to bend the hardline a small amount to help facilitate the extraction.

And finally, here's my "proof" I didn't pull the intake and cheat :D
http://forums.pelicanparts.com/uploa...1621524244.jpg

Now all of this information is not free. I'm trading this for info on how to get the #@$*! left pressure reg bracket lined up to get the 10mm head bolts back in. I've spent more time trying to get that f'ing bracket bolted back up, than I did pulling the T-line.

Looking good Josh!

myamoto1 05-20-2021 08:05 AM

Thanks Paul!

Oh and anyone making fun of my dryer vent heater hose, I'm accepting SCREET donations!

Lines are in and Fat Bastard rides again! Well, almost... still need to put the new windshield in or buy some goggles. Overall the kit from Paul is fantastic! Getting the lines tightened up before install is the key to no leaks, but guessing at the angle they need to be "locked down" at took a little bit of rework. Only issue I had was a small leak at the fuel filter. It was cranked down (crush washer installed), but required some thread tape to get a full seal.

New lines caused my idle to jump up to 2k RPM. A quick tweak of the idle-speed adjuster and I was back down to a solid 880 RPM. Looking forward to the first test drive to see if there's any noticeable improvement in throttle response.

Thanks again Paul for a great solution! Center lines to be replaced in the near(ish) future.

Mason_paul 05-24-2021 09:07 AM

Excellent! Congrats! That’s hard work for some great piece of mind :)
