ToddT,

I forgot to mention something funny. Just as you are thinking about abandoning the check valve system for a hydraulic/electric (hydraforce) frybrid style valved system. I am inthe SLOW process of replumbing my system from a Frybrid style 3 valve system to a check valve (FN74) system. (glad to see you on here Jason). The reason I am doing this is because the hydraforce valves leak by. You can see this on youtube videos and its even in their literature that they have a leak factor. Now many say it's at hi pressure but I have seen leakage when I have disassembled veg hoses at the valve and have had diesel in there. I originally went frybrid style when I reconfigured my roiginal GFS failure because I thought the Reg return was better than the deadhead. Well if there is any benefit its not worth the cross contamination.

Whats also interesting is the relief valve that Jason mentioned. With the reg return frybrid style you dont have the excessive fuel rail pressures Jason mentioned becaue all pressure gets dumped from the fuel pressure regulator. Others on this site and the frybrid site have mentioned check valve failures and huge fuel pressure spikes at start up with having check valve style plumbing. Due to this I am plumbing in a 100 psi relief valve that sheds excess pressure at start up back to the purge return to veg line. I have purchased kepner valves Pilot operated check valve|Miniature check valve|Stainless steel check valve - Inline check and relief/check valves with JIC ends set at 65 psi. I will have these valves for my two inlets for D2 and VO. The 65 psi are standard models but Unfortunately to get a 100 psi model with JIC ends there was a 100 set up fee. So I found a parker one on ebay with npt and sae ends. I would prefer to use JIC but money talks. To get to the rear fuel ports requires a little patience but is not impossible.

Big Steve,

Jason mentions something about heating the filter that I would do. Like the vegistroke system I use HOH which I think is fine and I am even using a reg return. With a deadhead you are even in better shape. I do use a FPHE for extra heat. I use the ARC filter wraps that get HOT!. I bought these from Jason way back. They are great and I have a switch to turn them off in summer when I really dont need them. Some guys have even put in thermal shut offs so they come on and off as needed. I am not there yet but would love to do something like that in the future

If you need anyhelp PM me.
