ford 6.0 injector size ??? help
 

hey im new to the diesel game and i have a question about the cc of injector i should go. i have a 2005 ford 6.0 with arp studs 5 inch turbo back egr delete and soon to get a sct tuner. i am wondering if i should get stock or 155 cc injectors for everyday drive and some times light towing. i also want to know if i need to upgrade my fuel system with 155 cc thanks

Well a fuel pressure gauge would be a good start, and you'll certainly want one if you upgrade injectors. Some guys can run 190's and have no issues with fuel, others have issues on stock injectors and a hot tune, so you really need the gauge to know for sure.

As for injector size... well that's up to you. You could certainly get 155's and do light towing and daily driving without issues. You could go higher too if you wanted. I would plan on doing a fuel system though anyways.

What Should my fuel pressure be at. How hard would it be to upgrade the fuel pumped around how much you think it would be

Should be at least 55psi or so. Ford says under 45psi is damaging injectors.

Depends what you want to do for a fuel system. Are you just going to add a pusher pump to the stocker? Delete the whole setup and go with an AD2 or what? You can spend as little as probably $600 or so on a pusher, I think the AD2 is probably closer to $700, or you can do a full setup like a sump feeding into a an AD150 pusher feeding a fuel lab pump running up to the heads and have a regulated return up on top.

There's more than one way to skin a cat here.

If you're keeping it mild, a pusher pump feeding the stocker is probably the best bet right now. A regulated return certainly wouldn't hurt the cause either.

What is the cheapest and best way to go to fuel the 155 is there anyway stock system will handel 155 cc if I get the fuel pressure gage to check my psi

About how dos an under hood gas pressure gauge run.

Cheap isn't the way you want to go when you're sending the life blood to a very expensive set of injectors.

I would do a fuel pressure gauge and an AD150 feeding the stock pump, as well as the blue spring upgraded in the factory bowl and 6.4 banjo bolts at a minimum.

Whitman, depends what gauge you go with. Gauges are something you definitely get what you pay for though. I think I paid around $135 for my Isspro EV2 0-100psi gauge.

I bought an Auto Meter fuel psi gauge and NPT to metric adapter. I installed it into the fuel pressure test point. This gauge is spendy, but you get what you paid for and it comes with an electric sending unit. Raw fuel in a direct pressure gauge in the interior is MUCHO BADO!!

Agree with Karl, you don't want a mechanical fuel pressure gauge... go electric.

ok sounds good what size nozzle should i go ?
