| Fuel Pump FAQ |
| What is an fuel pressure regulator? |
| An fuel pressure regulator (FPR) controls the amount of fuel that goes into the intake manifold via the vacuum line after it passes through the injectors |
| My car is jerking while accelerating. Do I need a new fuel pump? |
| If it’s not your engines tuning, jerking is usually the result of a faulty fuel pump. Follow the same procedure above to listen for the fuel pump. |
| My car won’t start. Do I need to replace my fuel pump? |
| In most cases, a vehicles failure to start is usually caused by a faulty , battery, alternator, starter, or fuel pump. If the first three of these parts are determined to be working properly, have someone listen for a vibrating sound that the fuel pump should make near your gas tank when your engine is running. In some vehicles you may be able to hear this sound better by turning the ignition key barely enough to start the engine. If there is no |
| How will I know when I need a new pump? |
| If your fuel pressure at wide-open throttle (WOT) falls off, that is a good indication that your current fuel pump can not provide the required amount of fuel. Either the voltage to your pump is weak, or your pump isn't manly enough. |
| Do I need an adjustable fuel pressure regulator, too? |
| Need... no, but you may *want* one. If you are modifying your vehicle for extra performance, chances are you will need more fuel for those heads/boost/etc. An adjustable fuel pressure regulator is a way to fine-tune the fuel system for maximum performance after you've added that new pump. |
| How long will it take to get this pump? |
| If I have the pump in stock, I'll ship it right out if you send a money order, or after your check clears. If I don't have it, I'll have to order it. That can take about a week. I primarily ship via US Postal Service Priority Mail. Priority Mail typically takes two to three days for delivery.. In the past, US Postal Service Priority Mail has taken as little as one day and as many as seven days. |
| What can I do if I need more fuel than the high pressure 255 pump? |
| If you need more fuel than that, you are pushing some serious horsepower. I know some folks that are actually putting two Walbro pumps in the fuel tank. I don't have any kits to do that, but customers say that it isn't too difficult. |
| Will you take my credit card? |
| YES! I know I used to say "sorry" here, but all the pressure from you folks has softened my heart. I looked into taking credit cards, but the bank wanted $700 just to setup the processing, and a percentage of each sale on top of that. That would force me to raise my prices. The only way I figured to keep my prices low for cash customers was to charge the credit card customers what the bank is charging me. |
