Excellent quality testers with a 1 year warranty. Please note that we have sold over 120 pieces of this jet tester model on eBay ourselves in the last 18 months and have received excellent feedback worldwide. This is a new listing due to changes to eBay listing policies. They undergo a pressure buildup test, fuel leak test, pressure gauge accuracy test, etc. This is done to ensure that our quality standards are always met. They are tested with diesel fuel in the same conditions as normal use. We have been a manufacturer and exporter of diesel fuel injection products for 35 years and have expertise in the field. Our products are extremely too.
