SST-TIM Posted December 13, 2021 Report Share Posted December 13, 2021 I added this kit, purchased directly from Avanti Motors years ago, and now the cloth hoses have disintegrated. The hoses are "in between" sizes available from parts shops. Does anyone know who is offering replacements that will fit the flanges mounted in the firewall?

Kodjo Posted December 13, 2021 Report Share Posted December 13, 2021 I bought "modern" hoses, made from papr and aluminium foil like these: https://www.leader-pieces-auto.com/?/catalogue/fiche/LPAQJHF2AAABA/tuyau-flexible-alu-carton-universel-diametre-40-mm-vendu-au-metre#nav Worked fine for my Avanti, probably also availeble in the states?

billsr2 Posted January 25, 2022 Report Share Posted January 25, 2022 Aircraft supply companies will have the correct size. Naturally! Link to comment Share on other sites More sharing options...
Wasjunk Posted January 25, 2022 Report Share Posted January 25, 2022 I just ordered some today. I will receive it tomorrow and report if it is correct and going to work. Dave Link to comment Share on other sites More sharing options...
silverstude Posted January 25, 2022 Report Share Posted January 25, 2022 (edited) Some vacuum cleaner hoses fit those points also / You don't want anything with a lot of corrugation as it will cause turbulence and slow down the airflow. The smooth the inside, the better Edited January 25, 2022 by silverstude Link to comment Share on other sites More sharing options...
Wasjunk Posted January 26, 2022 Report Share Posted January 26, 2022 I received the 1 1/4 inch ID hose today from McMaster-Carr. The hose fits very well. The hose is flexible but a little heavier than the original. This is a rubber hose with spiral core. Part number 53145K19 and is sold by the foot. I think it will do the job just fine as I have no concerns of turbulence in this hose. Dave Link to comment Share on other sites More sharing options...
Desert Driver Posted January 26, 2022 Report Share Posted January 26, 2022 My venting hoses were toast as well. Having given a lot of thought to cooling down the transmission shifter, I came to the conclusion it just wasn't worth the time or money to replace them. So I plugged the upper holes and moved on. The 700r replacement for the Borg Warner transmission improved things somewhat as engine rpms have dropped considerably. Now please don't get me started on engine compartment ventilation 🤬 Link to comment Share on other sites More sharing options...
