Default Dual Walbro Questions

Cut up the bucket and plumbed two pumps out to a -8 AN line to the fuel rails.
Keeping the vent and return line stock but after seeing the return line that's maybe 5/16 ths line go into a tube in the bucket that looks to be a 1/4 " at best I'm wondering if that return is big enough? The second pump is on a Hobbs switch so its not continuous but it's probably a lot of fuel returning to the tank. Anyone......?

i sealed up the return, kept the vent, added a bulk fitting for a return and added another bulk for another feed.

I kept the stock return on mine and have not had any problems. I was initially planning on upgrading the return line, but in reality I don't think it will ever return any more fuel than a stock system will. The way I figure, the time when the most fuel is being returned to the tank is at idle when the pressure is the lowest. That will be the same stock or upgraded fuel system.

Thats good! There's not a lot of room left in that bucket now.
What did you use for hose on the inside? I'm going with the socket -less. The stock car guys tell me they use it in -tank with no problems.

The line I have inside is basically just the stock clear accordion looking stuff.
