Has anyone on the Forum ever used a intake manifold mounted filler neck ??
I purchased one through Speedway,...it was a total POS from the word go,...I don't believe that there is a rad cap manufactured, that would stop this thing from spewing coolant. Anyway,..it's coming off, and I have ordered up a "Moroso", Manifold Inline Filler Neck,..( PN# 63420 ). Has anyone had any experience with the Moroso unit, ??
Thanks in advance.

Yes,..the rad cap is the highest point in the system,..but the rad cap is on the manifold inline filler neck,..not on the rad. I had the filler neck that was on the rad removed and plated over,...one can not get to the rad cap to fill the rad in the nose of the '39 Buick.
After I purchased the filler neck from Speedway,...I read the reviews ( DUH ) on the unit,...not too favourable at all. When I questioned Speedway Tech help as to a remedy,..they suggested I install a " Stant, PN# 10393 28 - 32 Ib. " Rad Cap,.....that worked for about 16 miles. The rad wasn't overheating,.( indicating 175 on the guage )..the coolant was just seeping out from under the cap while the engine was running. I removed the top plate of the unit that the neck itself is welded to,..and it's a warped looking POS,..both the base plate,..and the top plate sealed fine,..it's the neck itself where the cap is supposed to seal, that's the problem. The top looks like it may be clamped into some device while the top plate is being welded to the neck ( inside weld ) and it could be the clamping / holding device that is warping the lip of the filler neck during the process, in whatever sweat shop these things are manufactured in.

I can't answer your question as I don't have any experience with engine mounted rad caps/filler necks.
Based on your comment above though, would it be possible to relocate the filler neck to an area of the tank that would allow access to the cap?
Any chance of posting a pic of your engine compartment/rad? I had a very similar car with a SBC in it, and the top tank of the rad in my car was WAY higher than the thermostat housing on the engine. I can't seem to picture how yours is set up .... if your engine is anywhere near the same height (as mine was) in the chassis, and your top tank is level with the top of the intake manifold (mine top-tank mounted filler neck was probably 10+ inches above the engine mounted thermostat housing), then you should have a ton of space above the rad, to allow access to a top-tank mounted filler neck.
I guess it's really none of my business how you car is set up though .... bottom line is I don't actually have any info regarding intake manifold mounted rad caps, sorry.
Here are a few shots of my rad installation. My engine sits quite far forward in this car, ( not by my choice ) and the rad has to go forward and under the pointed nose of the top sheet metal. The car had a real small rad ( height and width ) when I bought it,..but 3 core. That rad too had an extension built onto the rad, with the filler neck protruding back toward the engine, ( still a PIA to try and fill, and it looked like hell ) . I bought a new larger, height and width 2 core aluminum rad from Charlie Thurman ( Superior Rad - Michigan ) , and built up my own rad support. As you can see in the photo,..there is a 3/16 " x 2" flat bar that runs directly across the top of the rad and attaches to each side of the rad support to hold the rad down, and in place. In the one photo you can see on the top right corner of the rad where they welded the aluminum plate over the old filler neck hole. The rad sits plenty low below the intake manifold,..where the filler neck now bolts onto. The filler neck showing in the one photo was one of the " hose connect filler necks " ( the hose running from swivel inlet on intake manifold, to filler neck,..and a hose running from filler neck over to rad ) which looked like a cobbled up POS when installed,..my reason for going to the manifold mounted filler neck.

Lots more fabrication work , on a track or bullet nosed styled car I seen where dude put a ford styled over flow tank under the drivers side inner fender panel , right behind the headlight . Access was thru a nice looking hinged panel . . I,ve also seen that done with rad over flow bottles an washer fluid bottles . to get them outta the under hood compartment ..77.

Came to conclusion that they do NOT manufacture a rad cap that will hold water in this unit that I got from Speedway Motors. Being as how this unit would accept a filler neck ( coincidently,.. identical to the Moroso filler neck ),...I ordered Moroso's filler neck ( $48.00 ) and bolted it onto the base unit. Moroso's filler neck is " stamped out ", identical to the filler neck that came with the base unit,..and is just as big a POS as the original filler neck,..water spewing out front portion of rad cap (s),..I tried 4 different caps. The stamped Necks are just too thin in the " lockdown " portion of the neck, for the rad cap to lock down, and seal as required.
Anyway,..ordered up a CSR, Billet Aluminum swivel filler neck,..problem solved !!
Thank You all for your input I appreciate it.
