AFM to Plenum Hose

[kingqa69]

hi to all,

i have been on the useful link site for the AFM to Plenum chamber Hose, and it takes you to Merlin Motorspares highlighting a 80-70mm Samco Extreme Reducer Hose.

However, the length of these in the Extreme range are 76mm (3") The distamce between the two flanges (AFM and Plenum) is 100mm (4").

Now i need to replace my old original one and this one would be too short. Samco do do a longer 80-70mm reducer in their normal hose range, it being 127mm (5"). I could buy one of these and cut it to the correct length.

Has anyone had any experience on buying/fitting any one of these Reducers?

I fitted a 76-80mm reducing hose, which is quite snug at both ends - check your proposed 70mm end is big enough. You will also need to re-position the afm mount to align the afm with the plenum (unless yours line up already), otherwise the reducer will fit poorly, although you can compensate by cutting the ends at an angle.

Good luck!

That Merlin Motorsport one is for the V8 - its listed under the stuff for V8 engines but I will change the name of it when I'm back on the pc - I can't edit it from my phone (unless someone wants to beat me to it).

Can you post a pic mine wasn't anywhere near 100mm apart I had to shorten that hose.

Don't wish to brag, but mine's 110mm long...

Graham, I have absolutely no desire to see the photo.

Mine wasn't 110mm long, but was 80mm wide tapering to 70mm

Does yours look like this ? (Back to the original topic pleeeeease!)

[Ragtop]

It USED to look like that, but I put an alloy spacer between the AFM bracket and the bulkhead to move the bracket upwards and forwards so the AFM lined up with the plenum, thus:

(close your eyes now, Glen...)

Good plan that looks better.
That Samco hose is blue it would match your coolant hoses ;-)
If you mount the jubilee clips the other way round you can get the screw heads underneath facing forward so you can still tighten it but they are not visible.
All just cosmetic

Nigel you are quite right the wrong part was under useful links - now corrected it is the longer one you need. Apologies.

Blue for water, black for air...

That's true, but I prefer them where I can see them. I DID put them underneath for a while, but they kept skinning my knuckles fiddling with plugs and other stuff under there!

Thanks,

yep, mine does look like your picture, both orifices in-line. i've just requested a classic black std reducer hose from a company called amber-performance on ebay. They work out cheaper than from merlin or demon tweeks.

thanks for all the responses.
