So I wanted to give everyone an update. I think I have it sorted. It’s another case of bad parts out of the box. Which is always the most...
Thanks! When I was running the Hardi pump my plugs all looked a nice light brown across all 8. It only had issues in stop and go idling. The major...
This is really helpful information indeed! I’m betting this is my main issue. I’m hoping to swap the lines around this weekend. I will let...
Carb floats should be fine. Rebuilt carbs with floats all adjusted to within spec. With the Hardi pump installed and no return the car was...
Ok I just read something else interesting. The Pierburg installation instructions say the paper fuel filter must be installed after the fuel pump...
I agree. This should be one of the simplest fuel systems ever. I’m not so sure why it is giving me such a headache. The only other thing I can...
Pump voltage seems ok. It stays over 13V and never stops running. I may pull the fuel filter temporarily and see what that does. It’s a brand new...
Well this is frustrating. I put the restrictor in the line today with a 140 pilot jet and it is equally as bad as without the restrictor. I...
Thanks guys! You are always such a wealth of knowledge! Every time I go to a FCA event I consider srr were losing the car as I can’t stand the...
Thanks! That is exactly what I needed actually! I thought the trinity could be nice to control the fans with AC pressure instead of simply on and...
I know this is a very old thread but I’m working on my AC and wanted to try doing the upgrade to the trinary switch instead of the old T fitting....
Thanks! That’s what I was thinking. I’ll go without the regulator and just to the 1.5mm orifice. I’ll keep everyone posted how it goes!
Quick question. Would you recommend adding a fuel pressure regulator between the Pierburg pump and the carbs as well or would having a properly...
This helps. So I’m guessing the restrictor from Riva with a 150 pilot jet in it should be ok then. It would give me the 1.5mm orifice the GT4...
That’s good to know. I’ll leave that part alone then. I checked the orifice just now. Couldn’t get my caliper in there with the airbox on but the...
No safety relief plumbing. All of it was gone when I got the car. Mine goes from the tank -> filter -> Pierburg pump -> carbs -> return to other...
So I swapped in the Pierburg pump this weekend and opened up the return line. In short the car drives much worse. It will run ok for a short time...
EVAP system is intact with all new hoses and cleaned and checked valve. The fuel system has all new hoses and filters as well as rebuilt and...
Thanks Steve! I had gone with the Hardi originally because I had heard good things about their quality, but you make some good points about the...
Octane is really only needed to prevent detonation, which should only be an issue with high compression. I have run 91/93 in the car before and...
