What's the tallest extended water neck that anyone makes.
I need one between 8 to 9 inches tall with a 12 an fitting to get my radiator cap above the radiator.

Ed how tall is that one.

The problem i have since it is a big block mopar our water necks are on the water pump which makes it 3 to 4 inches lower than your typical chevrolet.

My radiator is in in the same place place as your undercover which without running the big bulky moroso spacer between the the pump and the neck (that I have been using but looks like ****)it's just not tall enough.

I'm not near the car now so best to ask Scott Lemen.

This is the tallest one I have ever seen. Several places make the piece you would put in there for the AN fitting

That’s the one I use. I modified it and had it powder coated

A Meziere WP200 Dragster pump and you don't need a water neck taller then you radiator

I've seen you post this a 100 times and they just don't understand high and low pressure side of the cooling system.

You can lead a drag racer to a proper cooling system but you can't make them buy it. But thats ok.

How bout running the bypass line from the Tstat housing down to the radiator tank or suction side of the pump?

Ours are 6.5" tall - Thanks! The Moroso is probably the easiest to modify if needed, but Meziere makes a weld in machined top that could be used to make your own.

I don't have a problem with air in the system but i do have to use the moroso adaptor to get the cap high enough to just be even with the highest point of the radiator.

I don't believe the wp200 with the built on expansion tank would do me much better since the cap will still be lower than radiator.

Correct me if i'm wrong.
If my septic tank (radiator) at my house was a little higher than my toilets(radiator cap), before my tank got full i would have **** in my bathroom floor since the toilet is lower.

BTW i do run a meziere pump just not the dragster pump

This isnt a toilet. Your cap should be on the low pressure side of the cooling system and your putting on the high side. Listen to what the Meziere Tech dude is telling you.

Take a look at every cross flow radiator any USA auto manufacture has made and you will see 2 things, the radiator cap is on the opposite tank from the upper radiator hose and a recovery tank. Also make sure you have your pump turned on whenever you have the radiator cap off and you should be able to get all the air out.

Alright this got me curious, how do you get rad cap in low pressure side in door car where rad is below top of motor and it has a double pass rad? Just wondering is all.

If it's a double pass radiator the water neck will still go on the opposite side form the upper radiator hose. The coolant will have lost most of it pressure after it has passed through the top part of the radiator.

Like our WC0110 radiator

Ok just another question then.

Just say on the radiator you have posted what if the radiator cap was installed 4 inches down on the radiator instead of at the top. Can the radiator still get completely full?

No.

Double pass radiator without a cap. Only place to fill is at the intake.
