[280Z Fuel Pump]

Was needing to know what the best and least expensive fuel pump with automatic cut off is. My fuel pump for some reason will not cut off once the carb is full and floods it. I have a Holley 650 or 750 (not sure which) and I understand that the psi has to be around 6 or 7 (from what I've read). Any particular brands that are more bang for your buck? Thanks guys.

[280Z Intake Manifold Problem!]

Bought the studs I needed and position the gasket properly. Put the manifold back on and the leaking gas problem is fixed.....now fate has somehow slapped me in the face and now my "flap" on my carb is sticking.......wow. The red item (if you can't tell I'm completely ignorant when it comes to carbs) is somehow sticking when the flap is opened. Don't know what the heck is going on here. Also here is a picture of the fuel pump I'm using. And also for some reason THAT's not kicking on either. Touch it to the positive of the battery and it works. Wire it to an ignition fuse and nothing. Btw these problems did not exist before the installation of these studs.....what happened?

It's not the original pump. And the gasket came like that and for some reason shifted to that position when the exhaust manifold was put on. It won't move to the correct postition.

I'm not driving it at all since I found out the gas was leaking.

Sorry about the pictures fellas. They're up now. I took a picture of the brand name of the manifold. Just in case.

It's not the carb...the bottom of the intake manifold where it connects to the engine block is where the gas is dripping from. It's no where near the carb. I went out and bought 8mm studs that go into the block and they fit so I will try and see if that fixes my problem.

 

Still any reason why it's not idling?

[280Z Intake Manifold Problem!]

Ok. So I have a 77' 280Z but the efi has been swapped out to a Holley carb. Why they would ruin a perfectly good system beats me but they did before I bought it. So my problem is that when I start it up it will not idle. <Problem #1. Next when I do keep it running (have to keep giving it gas) the clutch acts as some kind of super gas launcher and when it's pressed to change gears the engine revs up to about 6 or 7k and I have to wait for it to come back down in order to change gears.<Problem #2. Well I decided to park it in the garage to fix it. I see that my headers are leaking air into the engine cabin and also the intake manifold is leaking GASOLINE ONTO THE ENGINE BLOCK! <Probblem #3. Well needless to say it's not going anywhere. I bought a new gasket thinking this was my problem.....wrong. Put the gasket on and it sealed my exhaust manifold leak but the gasoline is still leaking from the intake manifold. The pictures above show the intake manifold only has the screws on top to attach it to the engine. Now many people tell me that the headers are supposed to have some kind of extension that pushes the intake manifold down on the bottom....I do not see this whatsoever. So...in conclusion what am I missing here? I'm stuck in this pile of information that I can not use because I don't know if the headers are wrong...if the intake manifold is wrong...is it just the carb flooding it? Please help as this is my only mode of transportation. Thanks guys.
