Overall Assessment

Our product is consistently praised for its high quality, perfect fit, and solution-oriented visual design. Notably, it has been deemed highly effective in facilitating coolant recovery and eliminating air pockets from various car models. Users appreciate its ability to provide an alternate filling source without a hassle and recommend it for small, tight street rod applications. Some customers have even attempted to manufacture an equivalent product but found our version easier to use and more time-efficient. The product also stands out for its compatibility with a wide range of vehicles and its convenient application in moving the radiator cap to the system's highest point. Moreover, the product attracts and retains customers owing to its rugged material, which solves challenging technical problems. Even in contrast with higher-priced competitors, customers would purchase our trusted product again if the need arises.

great product

I have a 65 vette, I have owned this car for many years. I have never been able to bleed all the air out of the cooling system until I hooked up one of these.. It did a great job, no air in the system , runs A LOT cooler. Wish I would have just done this years ago. I give it a 10.

inline die cast filler neck, 1.5 inch hose

The unit would not function as is because no radiator cap could be used - even after buying the one suggested by your salesman. That cap could not be used until the filler neck was modified. The manufacturer should be notified so other customers are not so inconvenienced as I was.

I used this on my TBucket that only had a puke tube and catch can. There was no provision for recovering coolant because of the one way check valve on the radiator. I pulled the check valve off, installed a pipe plug and installed this water filler with overflow fitting and piped it to my catch can for recovery. It works great!

Great fit for my project.

I purchased this filler neck and it requires a deeper cap than I have on the radiator. If I want a 14-16 lb pressure which cap should I use? This is primarily a street show car and I don't want a high pressure cap blowing the other stock component in the system. , Ford, 351 with roller cam and aluminum heads
