Blanking Screw, For Twin 40's Inlet Manifold

[Mat-Moo]

Just noticed that my twin 40's manifold has 2 holes, one at each end. I presume this is for a take off, for air meter or servo... Neither of which I have! If anyone has blanking screws for this, or know what size they are? I'd be grateful (Big push on my project!)

hi mat

the holes you are on about will be a bsp thread i think ,

any plumbing shop will have a plug to blank of the hole.

i think either be 3/8 or 1/2 .

I grabbed a radiator bleed screw 1/4" today, and it fits perfect (not the nicest thing to look at, but at least I can sort it!). Couldn't find any blank 1/4" plates though?
