Guest Gp crazy Posted July 11, 2004 Report Share Posted July 11, 2004 can they go bad & what are the problem areas with one of these ? the reason im asking? i smell gas and it's damp on the outside? should i get a fuel rail with a reg. & just replace the whole thing with another unit ? or is it cheaper to just replace the reg? unsure what to do next thanks jeff b Quote Link to comment Share on other sites More sharing options...
DOHCRagtopguy Posted July 11, 2004 Report Share Posted July 11, 2004 You can just replace the regulator without replacing the fuel rail. Sounds like your inner diaphragm is shot. Quote Link to comment Share on other sites More sharing options...
Guest Gp crazy Posted July 11, 2004 Report Share Posted July 11, 2004 will that explain the rough idle only on start up cold and if it sits in the sun and bulids psi. in the tank it runs so much better ? thanks jeff Quote Link to comment Share on other sites More sharing options...
gp90se Posted July 13, 2004 Report Share Posted July 13, 2004 Did my TGPs yesterday, not hard at all on a 3.1 (if thats your motor). Worst part is gettin the PCV valve hose on/off, which I might remove and run 2 the rear of the TGP manifold where the brake booster hose would go. Just make sure 2 powerwash the lower manifold so u dont get shit into the motor thru the fuel injector holes. -Jeff Quote Link to comment Share on other sites More sharing options...
