Cons and Pros of FPR blue spring upgrade?

[ImStrokin]

Ive been looking into installing the blue spring udgrade in my truck but was just wondering what y'all thought of it. I know that it raises fuel pressure but is there any chance of it being to high and start blowing O-rings out. I don't have a fuel pressure gauge so im not sure what my fuel pressure is right now. Any help would be much appreciated!

No "cons" to the blue spring.

agreed, the pressure won't be high enough to compromise either o-ring

Just make sure you buy the Ford kit and not an aftermarket brand. The cheapest place to get it seems to be Tousley Ford.

Check fuel pressure first to see where you are. Unless you just want an excuse to work on the truck and spend 75+ bucks.

Thanks for the info.
Marty, how do I check the fuel pressure?

[Marty]

There are 2 ways I do it.

One is the test port in the fuel bowl - M12 x 1.5 and run a gauge up on the cowl.

or put one inline after the pump with quick disconnect fittings. That one is more involved... but this is how ford does it.

I understand the second option but you kinda lost me on the first one??

LOL sorry.

On the engine mounted fuel filter housing there is a test port. It is an M12 x 1.5. You need to get an adapter. Many places sell them. They need to be narrow enough to screw in and not hit the housing. Adapt that to some sort of line capable of holding at a MINIMUM of 100psi. Run that to a gauge you source with whatever adapter fittings you need and read your pressure. At idle and WOT is what you want to know.
