Question ????

Hi guys,
I shimmed my fpr today and at the firt try I got like 125 psi, I tought that was a bit too much so I made the shim a bit smaller but I am still getting like 100-105 psi
I just left it like that for now, but now my question is if it isn't going to hurt anything?????
Thanks for the help guys,

michael

Limit to 75 psi or less.

Otherwise, watch your fuel pump die on you in no time.

Plus, plenty of folks have played around with fuel pressures, and not many found any benefit in going beyond 75 psi. Depending on injectors, 60-70 psi seems to be a standard sweet spot, but varies with other mods and type of injectors. Mine runs best between 65-70 psi.

Thanks pocket,
The reason I shimmed the fpr is that my fuel pressure never goes over 45psi
We checked everything, we even lowered the tank and found nothing wrong.
I also cleaned the fuel bowl completely,put in a new filter and a new fuel pump and I still got the 45 psi
I will go and make my shim even smaller

I am using a small bolt (I think 5 mm) that I saw a piece off and put it in (I don't owe a bb gun)

small bolt is way better to use... i took a little screw off of a ball valve and ground it down to fit in the fpr cover. how are your metering your pressure?

on the back of the fuel bowl,just above the fuel heater plug, there is a hex bolt (I think they call it like that) that you can remove with an allen wrench
After having removed the plug I installed an 1/4npt x1/4 flare coupling to connect my meter

there is another spot that is better and will make easy to drain fuel filter also... hook a 5/16 hose thats about 3 foot long to the drain pipe that is passenger side of block, then put a gauge on it and turn truck to on position and open the drain valve to the fuel filter and it will go right to your pressure. take gauge off and tuck hose some where

fuel pressure gauge

What kind of gauge do you use, where do I get one, and how much are they?
