Dave,
Forgot to check your reply and work has had me hoppin the last week.

I know, I need to get her out and blow all the carbon out of her for sure!!!

Could be your injectors leaking?? The accumulator should do just that, accumulate pressure so you can start it after the car sits for a while. I saw one of the others w CIS post that his car was extremely hard to start after it sat, replaced the accumulator, and it cured the problem.

The pic where I've got the 2 padded clamps are where your second pump lives. I've got nothing but the hose at that point with the clamps.

Your update on the fuel lines and torque tube, etc are excellent!!! Keep up the good work partner!!!

Not sure about the accumulator. It shouldn't matter, with a good check valve, right? If it leaks down nw it's got to be something in the engine bay.

You've got to get that car out and drive it! If you lived local I'd offer to take it and blow the cobwebs out on a regular basis. That's probably all it needs. When you have a chance, I'd love to see a pic of how the hose is routed through the area where my second pump lives. I'm guessing there is no bracket to mount a pump?

Anyway, I managed to FTP my site update, but I can't load it in a browser to check it. Damned IB.

Dave,
Got the car buttoned up today and drove for a while. Have not started the car since probably May. CIS does not like to sit!!! Took about 4 cranks to start and it died several times. finally idled ok, but needs to be run. Hesitates at higher RPMs but last time I had it down it was the same. I ran her for about a half hour around town and it was a little better, but really needs a few tanks, some miles, and some f injector cleaner. Knock on wood, no leaks so far in the new lines. Will get her next weekend and take her out, will let you know how it goes.

Thanks for clarifying. Finished the line, clamps, etc, yesterday. Need to put about 2 gallons in her and a fresh battery today. Will crank up this afternoon and check for leaks. If none found, I'll drive her the rest of the day and then move her to storage about a mile away. Need to make room for wifey's new car.

In regard to starting and firing right away, I hear you. CIS should fire immediatly even after sitting. Until I want through all my pump problems, leaks, etc, the 79 could litterally sit for a month and would fire right up, every time! Faster than the GTS does for sure! Is there any chance your fuel accumulator could be bad? Is it original?

I meant the check valve that screws into the pump, not the tipover valve. Both fuel pumps have integral check valves, but IMHO the car is not holding pressure after shutdown. If I restart quickly, like when leaving a gas station, I touch the key and it's running. If it sits for 20-30 minutes, it will fire then die, then second try it fires right up.

The quest for perfection...

At this point (knock on wood) the part of the system w the check valve in it is holding up. I replaced that along with all the hoses from the intank pump all the way through to the hardline just in front of the rear wheel going to the front of the car several years ago and I originally used your website as a good guide. (Thanks!) So the silverbulit got new fuel tank, intank pump, new fuel line to external pump and new external pump, new line from there to accumulator, new accumulator and filter, new fuel line from filter to hard line, and new check valve. I'm just pissed as Classic Tube rebuilt all the hoses and 2 have failed!!!

Plan is to replace the section of hose today w the "cushion sleeve" around it. I got the stuff last time at H Depot. The stuff is for hot water heater lines and simulates the original sleeve around the fuel line on the 79 pretty well.
Post pics when you get a chance, I'll do the same.

Yes, it's been working perfectly for about a week now. The only glitch(aside from the usual glitches) that I ran into was trying to install a check valve in the system, it requires a change from a banjo bolt at the pump to a nut as with the later cars.

Dave,
Thanks for the tips, Finished most of the job today. I did this several years ago, but the crimp came loose and leaked fuel so I'm going w Roger's fuel line and hose clamps to hopefully cure the problem.

I took off the crimps at each end w a dremmel then installed the banjo at the Fuel pump, and the hard line at the accumulator. The 79 (slightly different from yours) runs linde about 3-4 ft between the two. I'll wrap the line with pipe insulation from home depot, reconnect and hopefully the clamps will hold. Seems that CIS runs pretty high pressure and that is probably what made the crimped lines fail.

I took a bunch of pics and will post on the process. Not sure if I can do as good a job as Dwayne at posting, but I'll try to document sufficiently. I'm assuming you finished the job and the clamps/hoses are holding ok?

Thanks, talk to you soon! Chuck

I should reiterate -- since there are no email notifications when messages are posted here, anything you post to this area may go unread for days. Private messages or emails will usually get you a faster response.

On mine, the two lines between the fuel pump and accumulator were the larger size -- the short line from the filter to the hardline that leads to the engine bay was the smaller size.

Note, I had to loosen (but not remove) the front gas tank strap on the passenger side to thread the line that runs between the two pumps. Also, you'll want to pull that line out from the fenderwell side, there is a wrap of tape around the line and the harness that will hang you up if you try to pull it out the other way.
