Hose sizes?
Jim@hts has what you need. MAF to TB is 3.50-4.00(the tb is a lil smaller than 4.0 but it works fine..mine does)
You are connecting the MAF to the inlet hat? I would guess that would be 3.50-3.50 straight coupler.
This will get you going, you can find all the sizes you need on HTS.com, don't be afraid to email Jim with what you need, he is excellent to talk to.
