what is best to get the GFS392 Performance or Competition setup. I just have crazy larry possible upgrade turbo later but mostly want to keep the truck a reliable tower.

 

In looking at GDP's site... both are now the same price, both come with the same components only the performance doesn't come with the new larger line from the tank, it uses the stock line. It's about half the size of the supplied line.

I'd get the Comp. kit cause as small as the stock line is... you have the pressure but, not volume. A big reason to change the LP.... more volume !! There's just a little more work involved.

 

The only difference is that the Competition kit comes with a complete new fuel supply line and a tuning kit for the bypass valve. Personally, I have the Competition kit with the bypass set around 32-33 psi. Works great and I'll never have to worry about it any longer. I would just get the Competition kit since it is the same price....

 

I chose the perfromance kit so i can install in parallel with the stock pump and switch between the two as needed (e.g. backup, low fuel,...)

 

That was a great choice.....
