5hp Nissan... convert to external tank?

[W0rdBuff]

Good day, Potterers!
After replacing my internal tank twice now due to cracks around the exit tube that leak fuel, I want to convert to an external tank. I know back in the day I saw a post or link somewhere with a parts list, how-to, etc but I can't find it now. Has anyone on here done it and willing to share know-how? Specifically does this part... https://www.tohatsu.us/index.php?main_page=product_info&cPath=1000_1005_1085_1086_10569&products_id=107496&zenid=h2thc980go5e63onhomreg5qq5 ... go through the motor housing where the petcock is located? Everything outside the motor... tank hose etc is easy to figure out. Thank you!

External tanks require the motor to have a fuel pump. The first thing to do may be to see if your motor has that. Or has a place to fit one that you would need to buy.
