Peter @ Swift auto (Gas Research/Performance Shop) is also looking @
if he can modify Inlet Mani' to allow better flow of LP vapour into runners when he sets up the twin convertors. This was the main prob with the old LPG set up on roo-ted engine that was running erratically lean as pointed out by Old Grey & matty88. Prob with this IM modification is there's really not the room to extend outwards the original IM where throttle body is located. The mixer will prolly have to go there still
