It’s built for custom EFI plumbing on swap projects and conversions—particularly 4.8L, 5.3L and 6.0L LS installs—but requires you to confirm plumbing, hose sizes, electrical capacity and pre-filter placement before installation. The package includes common adapters and a one-year limited warranty; professional fuel-system installation is recommended.\u003c\/p\u003e\n\n\u003ch3\u003eWill this work for my LS swap with a returnless rail?\u003c\/h3\u003e\n\n\u003cp\u003eYes, when your fuel rail is designed for a fixed 58 PSI supply and your plumbing matches the included ports.

It suits swap builders installing 4.8L, 5.3L or 6.0L engines, custom conversion shops, and anyone replacing a GSL392-style external pump—provided plumbing, electrical capacity and hose choices are correct. If you need a different pressure or a return-style system, choose a component matched to those requirements.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Is this pump compatible with return-style fuel rails?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: No. This kit is built for returnless LS rails with a fixed 58 PSI supply; return-style systems need a different regulator setup.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Does the kit include a warranty?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes.
