[DeTomaso] vacuum vavle source, fuel vapor venting question

[Doug Braun]

Paul,

	Why do you need a valve?  Why not just vent it the same way as was done on
the car originally which was through a carbon vapor canister then to the air
cleaner (which in your case would be to the inlet tubing between the air
filter and the air-mass sensor?

Afternoon all:

Need/want to vent fuel tank vapors on my EFI system back into the engine.

Looking for a source for a vacuum controlled valve that I can use for
venting fuel tank vapors back into the engine. I am looking for an in line
value/regulator that closes or restricts vacuum when engine vacuum is
applied and opens when then engine stops that I can run off one of the
manifold vacuum ports. I tried running a manifold vacuum line strait to the
gas tank and it started sucking the tank walls in, toooo much vacuum.

Other options include running the vent line to a filter or pluming a fitting
just before the throttle body and hooking the fuel vent line to vent any
fuel vapors

Thanks


Paul
