I've been tinkering with my ranger and I've found something interresting if I bypass my evap and put a throttle valve in line from purge system to the manifold I can regulate a vacuum on the tank the fuel cap breaks vacuum about every 20 seconds it makes a deep groan sound but doesn't seem to be damaging anything my ign gage jumped up to around 28-30 and I'm getting about 32 mpg highway I'm pretty stoked think I'm using the vapors of the top of the tank and the computer is cutting back on the injection rate. Any thoughts on what I'm doing hopefully I don't damage anything

Sounds encouraging keep us informed! I"ve always believed the carmakers are in collusion with the oil cos to depress fuel economy. My mothers 56 caddilac a 2 ton tilly averaged 29 miles to the gallon (Highway) when I used to borrow it for road trips back in the 60s. My buddy had a 78 rabbit diesel that got 58 mpg and he drove it like he stole it from his worst enemy. I had a honda civic that got over 40 on unleaded back when gas was 50 cents a gallon. Nowadays they crow about 35 mpg for a skateboard witha tin box on it!! This is progress??

I haven't done anything with mine, and I get around 25 for city driving, and when i was on the highway, I got 31mpg.
