7.🌲 bb mod shim low fuel pressure 

300,000 miles is not tired. I have seen many with 500k+ that are worked everyday.

Learning about mine, is a 02 and really enjoyed the truck

I have 295,500 Miles, she's got blow by she's old and heavy but would not trade for any 2020.

They have stiffer spring that can be purchased that dose the same thing. Just remember with the added fuel pressure causes more strain on your seals in the bowl and system. Can blow out the tired old gaskets and such ,causing leaks. Good job on the free mod and video

I love how your go too was to unload the parts cannon lol. Diagnosis... who does that just load up the cannon and fire away lol.

I have done this mod on 2002 7.3L, it works great becarefull and only use stainless steel bbs.

One should always pull fuel from a clean container to rule out other problems before doing the mod. I did the mod 5 years ago, and the spring did get wore out. Recently I was getting less than 45 psi under load with 60 psi at idle, 70 no load. From a clean container as well as from each tank. I pulled the spring and stretched it, tossed it back in and I'm back to 100 psi idle and 80 under load. I will be ordering the updated spring. Either from ford or online, depends on price and how long I have to wait to get it. I'm curious if I could make an old injector needle spring work though. I might try that today. My next mod will be a pulsation damper like cummins uses in their PT pumps to smooth the pulses (much like a pressure tank in a well, or a capacitor in an electrical circuit) . I just haven't decided how to build it. It's possible the plastic cup on the regulator is already serving that function but has failed. If so fuel pressure between pulses will drop off dramatically, but wont be detected on a gauge with an orifice. Before I put an orifice inline with my gauge, the needle was bouncing in excess of 60 psi . Which means the injectors are only sometimes getting 60psi. Sometimes less. I will investigate this further. Bb mod is great, but it's not a long term solution, the spring should be replaced with the updated spring and then shimmed with shims from an injector kit or other similar type of washer/shim as the spring wears out. An inexpensive oil pressure gauge can be used to monitor pressure long term on the dash, it threads in where the shrader valve is. I will note that 200 psi will cause a hard start and poor running. I was playing around to see how high it would go, and anything over 100 psi is not recommended. A 700 hp drag truck uses 67 psi. So I would be shooting for 65-70 under load.

Damn cuz...did you just kill someone....you're shaking bad enough to get the grease out of fried chicken

Will this mod help fix me not getting fuel in my bowl?

it's your in tank screen plugged up

Have a 97.7.3. Changed the mechanical pump (Carter) two years ago along with fuel bowl assembly, hoses etc. Started leaking fuel in th o the Valley, what could be most probable cause?

will this work if you have a electric fuel pump i have a 7.3 obs

lots of electronics on there haha

I have the same truck but it wouldn’t turn on it says it doesn’t have gas and it has full tank it started for a minute and it went of again I will really appreciate your help

put magnet on the pinchers

Have 2006 6.0 powerstroke starts and run a min. then shuts off have replaced fuel pump

What was your old fuel pressure psi before doing this?

Did you notice a difference after your fuel pressure went up, as far as idle and power?

Clean strainer in fuel tanks.

What was the problem getting low fuel pressure? I just replace my lift pump and still my truck won't start

I must say, these trucks do have a ton of electronics and bullshit. they just haven't gone bad. wait til they do, like on my truck ;) it's a blast haha

Okay I agree with electronics but Jesus the 7.3s have a lot of sensors for every damn thing on the truck

How much higher did you feel pressure go up

I’ve changed the fuel regulator my cps my ipr my hpop my fuel lifting unit and stil no start do u think my idm is bad

How do you know you have low fuel pressure?

STILL HAS A COMPUTER CALLED ECM.

@4:02 (For others watching) If you have issue getting the piece out-lay a rag down and start/turn off the truck-the pressure will push it out

I did this on my '95 with 280'000 and my #5 injector went out a week later. Don't know if the bb mod caused the injector problem but it cost me friggin' $700.

It does have electronics😂 omg

Has anyone done 2 bb's

"I don't have any electronics". That lets me know you don't know squat about this motor. It relies on electronics and without them it won't even start.
