I'm looking into getting a K&N flame arrestor for my 500HP carb. K&N part number 59-3370. Does anyone know the vent tube kit part number I would need? Will the Merc ones fit on the K&N?

Anyone running these arrestors? Is it worth the $100?

i just ordered the same thing checkmate f1 ordered. it's not for marine use though.

K & N is very serious about their CARB and Coast Guard ratings but I put a standard 9" x 2" on my boat and it worked great. The part number was 60-1110 (I think) and it came with a stainless steel top and bottom with the preferred air horn design and which had the 5/8's tube built righ in. It was around $60 from Pep Boys.

DK,

Checkmate's post is what got me interested. I ordered the #59-3370 (CG approved) and 2 vent kits. Part number 85-1662. It was about $150 for everything including shipping.

29,
i'll look into the kits. mine should be here today.

Envision,

I went to my local Pep Boys and they only had Edelbrock garbage!

DK,

Did you get it yet? Did you get it..huh..huh?

I just got the confirmation that mine has been shipped. I got it with the previously mentioned valve kits. I'm still going to see if the Merc vents can be carried over.

Try K&N's website:

They have a marine section that lists everything. The vent tubes can be ordered seperately to fit each size of tube that you need.

THE VENT HOSE ADAPTERS LOOK LIKE THEY'D WORK PERFECT!

i put mine on last night and used the old adapters out of the stock arrestor. i made it work, but the k&n adapters are much better.

Mine should be here today. I did order thw vent kits. I'll see what works best.
