: Our fuel injectors are manufactured strictly for use with high performance engines for racing and off-highway use only, and are therefore subject to the unusual stresses normally associated with this type of use. Since the operation of these engines is far in excess of the safe limits that are usually set for engines, breakage and failures are common, and are an accepted risk in racing. Also, the history of racing has always been one of trial and error by the users of this type of equipment. Therefore, because of the many unknown factors involved in experimentation, and because of the safe limits being exceeded by virtually every part in the engine, we do not offer a warranty of any kind on our equipment. It is purchased and used by the buyer at his own risk and with this understanding. If any of our parts become defective after purchase, the buyer assumes all cost of service or repair.

: Fuel Injection Engineering (FIE) is providing all information herein to familiarize potential customers with its’ products and services. Because racing is inherently dangerous, no representation of your safety is implied. To the extent permitted by law, this warranty is exclusive and in lieu of all other warranties or representations, whether expressed or implied, including any implied warranty of merchantability or fitness for a particular purpose. In no event will FIE be liable for special or consequential damages.

About Weldon Racing Pumps

Industry wide, the Weldon Racing Pumps name has been synonymous with top quality fuel delivery components….but we’ve heard this claim before, about a wide variety of aftermarket suppliers.

Knowing that the fuel system components would reflect the quality of the EFI kits produced by Hilborn, we elected to test the fuel delivery components from various manufacturers. Our testing found that the components from Weldon Racing Pumps were not only the most consistent, they routinely out performed their published spec information.
