What’s wrong with my Regulator?
Regulators are a complicated and intricate piece to any car assembly. Have you ever found that your once perfect regulator now isn’t performing to your standards?
Here are some troubleshooting tips that might have some solutions for you.
If you find that your regulator doesn’t work anymore:
- Ensure that all ports are clear and free of dirt/debris.
Regulators need the fuel to be clear of small dirt pieces and general debris in order to perform optimally. Clean out any ports if you find that your regulator is running into problems.
- Don’t use any adhesives that could break off or somehow get into the ports.
A lot of builders choose to use liquid teflon to seal their ports, which is much better than any alternatives as it leaves little to no residue that could find its way into your regulator.
- Only check the pressure when the car is running.
You won’t be able to get an accurate reading unless your car is running, make sure it’s on!
- Mounting Distance
Ensure that your fuel pump is a safe distance away from your fuel pressure regulator and that it is at a good pressure. The recommended pressure is 30 – 35 lbs of pressure. If the pump is mounted on the back of the car it should have 30-35 lbs of pressure. If it’s mounted towards the front of the car you might need to turn the pressure back so the regulator works properly.
- Be sure you know the type of regulator you are using
Different regulators have different capabilities. For example, a return fuel pressure regulator can run more pressure, and it will return any excess fuel. A standard regulator may not be able to handle the same pressures as a return regulator but will do the job just the same.
