fuel systems

[7.3ford350]

just wondering what my fuel presure should be at ideling? i am looking to add a fass fuel system , but i dont no how big of a system i want to do ? would 90gph be good or should go with 150,180? i dont no witch one i want to do or witch would be good for me. i gotta chip,intake, exhaust and planing on doing ww and maybe injector later on down the road, no time soon. thanks.

I would look into a regulated return and in tank mods first. The stock pump will supply enough fuel for 180cc injectors. 180's require 30gph at 2600rpm. The stock pump can flow 32gph at 60psi. I would wait on the FASS until you get the other stuff done since it will have to happen anyways with the FASS. There are other options as well. You can get a pump that will flow 40gph at 60psi that will go in your stock fuel pump location for $120.

I guess if you want to spend the money and brag that you have a FASS it is a no brainer. But if you want to save some money to help fund the injector upgrades I can give you some more info.

so what would be a good option for me to do to up my fuel presure some and replace my fuel pump . just make sure they have planty of fuel and nothing will go wroung.

Regulated return from ITP and fuel tank puck up mod. Then add either a Walbro 255lph or Bosch 044 pump in the stock location. That would provide you with enough fuel to supply 240cc injectors without any problems. I have the walbo pump. It was $120 and the fittings are extra. It will mount in the stock location. Do you currently have a fuel pressure gauge in the cab so you can see what the system is doing?

no i need to do that also....but i would like someone to help me when i do it becouse i dont no exactly what i am doing. how much would that setup cost?

[strokin_early_99]

I guess lets start over. What are you plans with the truck performance/power wise?

Idle pressure should be around 65-70psi. You will need to shim the fuel pressure regulator to get that but it is an easy mod.

all of this talk about shimming how do you do thius

According to Ford stock FP is between 40-60psi at idle. Seems like a huge spread to me, but this is the spec.

For the how to on shiming the FP go here.

i am not sure how much i want to put into it.. i mean i would like to have a 450-500hps truck but i can do that now...i got a tony wildman chip,intake,exhaust,gauges and looking to do a ww and might be able to do the sticks this summer. i want to get the fuel system pumped up some becouse i think my fuel pump is going out anyways, and i am lousing little bit of fuel presure. this is what a ford feild engineer said to me, so i want to upgrade the fuel system to whatever i need. the itp setup you(stroken early 99) where talking about sounded good to me but then again i dont no what i am looking for or need..but all in all in about a year i might have the sticks.
