MGB SU HS4 Carburetor Nitrophyl Float – ROYZE Float Chamber Lid (378-470 Style)

Hey MGB guys—keeping those SU HS4 carbs happy?

Here’s a fresh Nitrophyl float for the float chamber lid.

It’s made by ROYZE and it’s the right one for the job.

If your old float is sunk or not doing its job, your mixture’s gonna be all over the place.

Swap this brand-new one in and get that fuel level back where it belongs.

It’s a small part, but it makes a huge difference in how the car runs.

Direct fit for the HS4 setup.

Don’t let a tired float ruin your drive—grab this one and get back on the road.
