2g fuel tank getting alot of pressure

[melfesto]

hi all the problem i am having is the fuel tank is building up pressure. I just finished installing a dual pump hanger with 2 walbro 255 pumps i have a afpr and its set to about 45-50 i belive. once i finished installing that i noticed i was getting a check engine code for the evap purge solinoid. The pressure in the tank isnt like vacum its actuly pushing some gas up the inside of the wire that goes to the fuel pump inside the tank into the cabin. be it a small amount i really need to find a fix for this before i have to play put the flaming car out game. Any ideas guys.

Did you remove your emissions? Such as charcoal canister, etc?

Have you actually driven the car or just idled? The purge valve stays closed at idle.

all the emissons stuff is still in the car and hooked up and yes the car has been driven i am pretty sure the solonoid is shot would that be the cause of this. also this does it when the car is off and its a warm day it will build up to.

Yes, a EVAP purge valve that won't open matches your issues.

anyone happen to know the part number for this. I went to advance and asked them if they could look it up and they looked at me like i had three heads when i explained what it was. Needless to say they couldnt find it in the system.

i cant seem to find it in caps either anyone know the P/N for this or where i should go to get a new one?
