Does anyone know which company makes the bypass valve/fuel requlator that GDP is using in the Walbro kits?

I ran into this myself. The last time I went to their sites I couldnt find it. I finally just changed mine to a Mallory part#4307M, which I got a Summit racing. Fully adjustable and it working much better than the other one I had

i made my own with a #8 orb check valve and swapped out the spring for a stiffer one. .
