59 johnson 10hp fuel/air line question

[fishindad]

I've got one of those old pump tanks with the dual fuel/air lines. The lines for it are not terrible but I am replacing them with new. I got 2 10' sections of 3/16 fuel line to replace. Planning on using this line for the air and fuel line since it is easier for me to get than buying the expensive dual line available online. This fuel line will hold 50lb of pressure. Will it cause me trouble if I use it for the air hose too?
Any advice would be appreciated.
Thanks

That should work if they fit snug. May want to tie the lines together every so often. You may want to try posting your other questions on http://www.aomci.org/cgi-bin/yabb2/YaBB.pl

The only thing that may be a problem is the lines you have my be too thick walled and you may not be able to get the fitting onto them side by side.

I use 5/32" BRP lines to replace the fuel/air lines under cowling to motor coupler, they fit perfectly. I personally use aftermarket 2-line hose from coupler to tank, but it is spendy. If it'll last another 50 years, what the heck

thanks for the info. I'll try the 3/16 that I have. If it doesn't work then I will look into The 5/32.
Appreciate it.
