vent soleniod and gas cap removal?

[DOUGLASMELTER]

wow...you all should see what a sticking fuel pressure regulator can do to fuel trims....that was a crazy couple days of problem solving. in trying to find the problem ive found just how hard the fuel pumps work< even with the vent soleniod open > at different levels of the tank being full. in seeing the pump work harder at different times i decided pump life would be greatly increased with the removal of the vent soleniod and with a small whole in the gas cap. anyone ever try this before and does it work?:th_scratchhead:

come on now.....someone has got to have tried this before... hell hook up a dc amp meter to your power wire to your fuel pump at full tank, empty, and with cap off and you will see a huge difference. anyone?

I guess I already did something similar, but not for the reasons your talking about, so I can't comment about any differences or anything.

how did you do it and why? did you do it the same way im thinking of or differently?

I have dealt with EVAP problems on far too many cars, so when I had my tank out a while back, I just decided to get rid of the system. Call it preventative maintenance.

I removed the charcoal canister, and spliced the lines going into it and coming out of it together. This gave me a straight shot from the tank vent up to the vent canister. I then removed the canister and replaced it with a breather filter, although I don't think that's necessary. If you just unplug the solenoid, it should stay open and the canister would act the same as my breather filter.
