To increase the fuel pressure,
turn the adjustment screw counter-clockwise
. This will cause the spring to exert more pressure on the regulator diaphragm and regulate at a higher pressure. Monitor your adjustment with a fuel pressure gauge.
Why does systolic blood pressure increase with major head injury?
The medulla can no longer detect signals from the baroreceptors telling it to dilate the arteries.
Damage to the rest of the brain makes the brain stem think the body is in distress
, causing it to raise blood pressure.
How much pressure does a TBI fuel pump have?
The fuel pressure regulator is set for
approximately 12 psi
(30 psi on ’94 & ’95 BBC trucks). With a service range of 9 to 13 psi being considered good. This equates to a 17% to 20% change in injector flow rate over the service range.
Can a brain injury cause low blood pressure?
Severe traumatic brain injury (TBI),
concussion
(mild traumatic brain injury or mTBI), and other head trauma can cause high blood pressure, low blood pressure, and other circulatory system changes.
How much PSI does a TBI need?
TBI only runs at
about 15 psi
. TPI needs more like 50-60psi.
How do you check fuel pressure on a TBI?
The fuel pressure regulator is set for
approximately 12 psi
(30 psi on ’94 & ’95 BBC trucks). With a service range of 9 to 13 psi being considered good. This equates to a 17% to 20% change in injector flow rate over the service range.
How do you know if your fuel pressure regulator is bad?
Early signs of a failing fuel pressure regulator include
engine misfires and poor acceleration and fuel mileage
. The reason we batch them together is that each is caused by the same thing, the air/fuel mixture being off.
What are the symptoms of a slow brain bleed?
- Head pain.
- Neck or back pain.
- Neck stiffness.
- Vision changes.
- Photophobia.
- Weakness on one side of the face or body.
- Slurred speech.
- Lethargy.
What is the most common complication of a head injury?
The most common short-term complications associated with TBIs include
cognitive impairment
, difficulties with sensory processing and communication, immediate seizures, hydrocephalus, cerebrospinal fluid (CSF) leakage, vascular or cranial nerve injuries, tinnitus, organ failure, and polytrauma
What are the signs of a head injury?
- Raised, swollen area from a bump or a bruise.
- Small, superficial (shallow) cut in the scalp.
- Headache.
- Sensitivity to noise and light.
- Irritability.
- Confusion.
- Lightheadedness and/or dizziness.
- Problems with balance.
What are the signs and symptoms of neurogenic shock?
- dizziness.
- nausea.
- vomiting.
- blank stares.
- fainting.
- increased sweating.
- anxiety.
- pale skin.
What is an injury that is defined as injury to the brain?
A traumatic brain injury, or TBI
, is an injury that affects how the brain works. TBI is a major cause of death and disability in the United States. Anyone can experience a TBI, but data suggest that some groups are at greater risk for getting a TBI or having worse health outcomes after the injury.
What causes hypotension in head injury?
1,2 Hypotension in TBI patients is generally caused by
substantial blood loss due to extracranial injuries
. 3 Significant haemorrhage decreases stroke volume and cardiac output causing the body to compensate through systemic vasoconstriction.
How much fuel pressure does a carburetor need?
Fuel pressure should be set
between 6 and 8 psi
for a gasoline carburetor. An alcohol carburetor is a different animal with very different requirements. The Alky carburetor will require 4 to 5 psi at idle and 9 to 12 psi at wide open throttle. Remember, fuel pressure is not a substitute for volume!
How does a bypass fuel pressure regulator work?
With a bypass style regulator,
fuel enters through the inlet port
(A) and travels past a fuel bypass valve/fuel return line port (which governs fuel flow and pressure) (B) and then is distributed through an outlet port to the carburetor or EFI fuel rail (C).
What is GM TBI?
The GM TBI is
a speed-density system
, which assumes the engine ingests a given amount of air at wide-open throttle (WOT). Mass airflow systems measure the air entering the engine, but speed density systems like those used on these TBI engines do not.
