When shopping for fuel pumps, most customers out there tend to have difficulties choosing on whether to go for internal or external fuel pumps, based on their preferences and the amount that they are willing to spend. In simple words, the choice will be dependent on the application of the said fuel pump.
It should be accounted that even though most vehicles will benefit more from internal fuel pumps, external ones are better in applications which require ultra-high horsepower. Furthermore, external fuel pumps like Bosch 044 fuel pump can be easily built to support more horsepower than internal ones. Therefore, in this article guide, we’ll be discussing some of the main concerns that vehicle owners tend to have regarding these two types of fuel pumps.
Everything You Need To Know About External And Internal Fuel
- Analysing The Cost Between The Two
The cost will always be parallel to the application for which the fuel pump is to be used. The price will be dependent on the design of the fuel cell, the filters, the pump design and the like. There will be times when some systems will be cheaper to build externally, while other times it’d be cheaper to opt for internal fuel pump systems.
Therefore, you need to look at your use case scenario and then go ahead with the most efficient option.
- Analysing The Better Option Between The Two
As it has been mentioned earlier, the answer will depend on the purpose for which you’d be buying your fuel pump. This is because your application for the pump will matter more than the actual location of the pump. If your pump is equipped or placed accurately, then it should be remembered that external designs tend to be more reliable and serviceable than the ones that are fitted internally.
With that being said, internal fuel pumps can also deliver fuel consistently as long as the pump has been matched with the output of the engine. In the earlier days, internal fuel pumps have always been problematic when trying to install them, since the only way you can mount them is either through the manufacturer or service centre mechanics. The reason is because when it comes to installing internal fuel pumps, the entire fuel cell needs to be pulled apart.
But, in recent times car manufacturers are moving towards a modular approach which means the cost of addition of internal fuel pumps has decreased significantly over the years. Part of the reason why some internal fuel pumps tend to be cheaper than external ones. But when it comes to real-world performance, external fuel pumps are hard to beat from a functional viewpoint.
When deciding on where you’ll be placing your fuel pump you need to check the amount of horsepower your vehicle’s engine will be outputting along with the amount of fuel that is to be consumed.
