ASSEMBLY OPTIONS
- Kit Only:
- Our design was targeted to remove the need for sending your fuel pump assembly in for modification. Following the provided instructions the average home mechanic can assemble and install our kit. This means less down time and a great reduction in both assembly & shipping cost as well. Best of all you end up with your pump in the condition it was in when you pulled it from the car and run no risk of getting a housing back that is in poor condition.
- Install is easy there is no guess work on engagement and sealing of o-ring or complications and risks tightening clamps that can poke holes in critical plastic components near by.
- New Build (Fully Assembled):
- If you prefer to have someone else do the work we are here for you. We offer 100% new builds please allow 2-3 business days for assembly. This option is great for the customer who plans to have a shop do the work. For about the same price you will pay in labor at the shop for assembly you get an already assembled unit ready to drop right in. So if you are looking for a 100% assembled drop in ready solution this is the choice for you!
While all bucketless fuel pumps flow .2gpm more than a bucket design that retains the venturi it comes at a cost. Bucketless pumps should not be driven on tanks lower than ¼ full and should not be used for road course racing. This is not a disadvantage of only bucketless designs but also a disadvantage for any bucket design which deletes the venturi. If you do not plan on road course racing (not street racing) and are responsible at maintaining ¼ tank of fuel during spirited driving bucketless pumps can be a cheaper alternative for you.
* To reach the advertised ability of these fuel pumps, the use of the Precision Raceworks In-Tank filter regulator assembly is required. See it HERE.
** Some European Spec vehicles may require re-use of top hat due to differences in emissions requirements.
This is a true plug and play solution that anyone can install in their home garage and start taking advantage of the benefits right away.
