Rail pressure relief valve and capping: a dead horse?

[srichard]

I have had performance issues with the truck for a while, and i am pretty sure it is due to a failing pressure relief valve. I will confirm that this weekend.



Anyway, my only relevant mod is a quad race box, which isn't supposed to raise the pressure too far.



the question I have is: do I want to replace the pressure relief valve with another stock one, or wait for a modified one to be release to the after market, or just cap the rail and fuggetaboutit?



the obvious concerns are:

- stock will possibly fail again, at $350+ a pop, I don't want to keep replacing

- aftermarket isn't out yet from what I can tell, and they might still fail but will be rebuildable

- rail cap is a concern because I would be losing the fail safe and putting even more stress on the injectors.



so, what would YOU do?



thanks in advance for any information and/or opinions you may throw my way.

Cap the rail and cap the pressure box.

"cap the pressure box?" as in "get rid of it?"

I would keep it but only use it when competing.

ditto what Justin said. I did it a couple months ago and haven't looked back.

i agree, if you do use it use in moderation... ... ...
