This petrol pump is a product of the highest quality with the best price/performance ratio, which is also quieter than the OEM original. Only the pump (not the casing) installed in the manufacture of the vehicle is replaced. HFP is a brand name and certified by RC Engineering QS9000. This pump is efficient, quiet, durable and designed for the high pressure in modern vehicles required in fuel injection. The production of HFP pumps is subject to strict quality controls, and are designed and designed for trouble-free operation of at least 160,000 km. All HFP pumps come with a lifetime replacement guarantee. This replacement pump fits directly into the original fuel pump housing. To fit this pump, you must use the original manufacturers housing. The case is hardly defective. If your level indicator works, the case is usually fine and reusable. This is another reason why the HFP pump is more cost-effective - you dont have to change the whole pump and housing. You just need to open the housing and replace the pump.
