Wide open throttle bog when accelerating issue.

Bait-and-switch is ILLEGAL. (At least, in the USA.)

If you don't complain and get justice, they'll screw more people.

 

Try putting a hose on inlet side of pump about 3-4 foot long into a gas can to by pass whole system.

 

Well, I finally got back to working on the car. I ended up with one Stage 1 pump. I ordered the last two that PartsAvatar in Canada had. They were Spectra SP1263MP pumps that are supposed to be the Stage 1 pumps. I was away working and my wife sent me a picture of one of them and I realized that it was the standard pump with the Stage 1 part number on it from Spectra. She did not look at the other box. I finally had some time to look at the car and I opened up the boxes to find one Stage 1 Pump. At least I found one of them.

I installed the Stage 1 pump and modified the fuel lines again to work with my System.I took it out for a drive and I have plenty of fuel pressure now. I actually have too much. It is 10 or 11 lbs at idle. I have 8 lbs wide open throttle. No issue with running out of fuel now. Car is running good. I went out to a Fathers day car show about 45 min away and had no issues. I may have to regulate the pressure but the float needle is handling it fine at the moment. Glad to get the car out.

 

Is your pressure gauge accurate? I would not expect the needle and seat to handle 11 psi. What is the diameter of the seat orifice?

If that is a liquid-filled gauge, did you "burp" it before taking a pressure reading? It'll have a rubber plug on it somewhere. Tilt the gauge so the rubber plug is "up", burp it like Tupperware. THEN take the pressure reading.

Twisted-wire "hose clamp" on the vapor return hose? I figured those would cut into the hose and cause failure given some time.

 

I did have a wet line into the car originally so I could watch it while driving. It is a new gauge. Since I had plenty of pressure I moved the gauge out to the engine. I had bled that line. I did not know there was a bleed on the gauge. I just cracked the line to bleed. I can try to bleed it where it is installed now. It is not a liquid filled gauge so it bounces around pretty good as it is installed now. It was nice and steady when I had it remote mounted on the wet line. Lots of line to absorb the pulses. I don't remember the size of the needle seat in the carb. It had the huge one in there as it is an Edelbrock Performer RPM Q-Jet. Cliff Ruggle put the kit together for me to tune it and recommended a smaller seat so that is what is installed now. I am not too worried about the safety wire on the rubber cap plug. It will not be there long. I just did not have a clamp that could tighten that small. I will still pick some up. I was just getting it together last night so I could make it out to the show today. I may well plumb a return line but that will take some time. I was thinking of putting a line from the return into a bucket to see if it makes a difference on the fuel pressure.

Every Q-jet that I have likes 6-6.5 PSI regulated....but I run the large .149 needle and seat. Smaller needles like and need more pressure.
