my hose lines are not the standard 1/8" as sold on devilsown. my lines are all 1/4" aside from the check valve which is 1/8"(has adapters on both sides) and my nozzle size is an M3. can anyone calculate how much pressure is being used? im somewhat going through a hectic time trying to run KR-free but only be able to run almost KR-free with a 10.7-11.0 on my WBo2. i was thinking if my lines and nozzle would play a role and make me run too rich? i tried leaning my fueling to command a 11.5 AFR but i get alot and constant knock. just curious if its a possibility. thanks in advance.

Even with the larger hose the nozzle makes it a non factor, The nozzle size plays the greatest role in output pressure on the hose. The 1/8 ID vs 1/4 id will be less than 15psi difference.
