Assembly options
- Kit Only: Designed so you do not need to send your fuel pump assembly for modification. With the supplied instructions the average home mechanic can assemble and install. No guesswork on O-ring sealing or risky clamp tightening on surrounding plastic.
- New Build: We can supply a 100 percent new build assembled unit ready to drop in. Please allow 2 to 3 business days for assembly. Ideal if a shop is fitting the part. Select assembly and specify FWD or AWD where applicable.
Bucketless note: while bucketless pumps can flow approximately 0.2 gpm more than a bucketed design that retains the venturi, they should not be driven below a quarter tank and are not recommended for road course use. The same caution applies to any bucket design that deletes the venturi.
