Holley EFI Fuel Tank Module - 350 LPH - Mustang, Falcon Cougar

In-tank fuel pump module for 1974-1981 Camaro Firebird. Supports Up To 750 Horsepower.

Overview
This in-tank fuel pump module is a high-pressure unit that flows 350 liters per hour (LPH) and is capable of supporting electronic fuel injection (EFI) engines producing up to 750 horsepower. A pre-calibrated fuel-level sending unit designed to work with the factory fuel gauge for this application is included. This module also features a HydraMat filter which has a unique internal reservoir that keeps fuel available at the pick-up and also provides protection from contaminates. Fuel pressure is internally regulated to 58 psi eliminating the added expense and effort of purchasing and installing an external fuel pressure regulator - no separate return line is required because this module returns excess fuel right inside the tank! This 1977-1981 F-body Muscle Car EFI Fuel Pump module was designed as a direct replacement for your factory pick-up and sending unit. There is no need to purchase a custom EFI fuel tank. You can even retain the factory fuel hard line - just connect the outlet of the pump module to the hard line on your vehicle with EFI-rated fuel hose and hose clamps available in the Earls Vapor Guard line. This Muscle Car EFI Module includes a 350 LPH fuel pump and a Holley HydraMat. HydraMat is an amazing patent-pending fuel reservoir system that reduces fuel starvation issues that might otherwise occur while cornering, accelerating, stopping, traversing inclines, and during low fuel conditions.

*** Notes for the 1980-81 Firebird/Trans-am applications and any older model Firebirds that have swapped in a Chevrolet small Block engine.. If the your car was equipped with the SBC (305 and 350) engine, the fuel line was routed up the passenger side of the chassis like our 12-374 is designed. (SBC fuel pump on passenger side of the engine. Just like Camaro with SBC) If your car was built from the factory with the Pontiac or Oldsmobile engine (mechanical fuel pump is on the drivers side of engine) , they ran the factory fuel line up the drivers side of the chassis. Thus, using a different fuel sending unit from the factory. Modification of the fuel lines will be necessary when connecting the 12-374 to the Pontiac/Oldsmobile engine chassis plumbing.

Don't recommend.
Format: Paperback, Format: Paperback
Not at all what I was expecting. It must have been self or independently published. Returned. I will definitely be scrutinizing my next book purchase on this subject to more stringently. Also, Not that I care but claiming to be "7 books in one" is a false claim. But I kind of figured that before I purchased it. Its just bad. Big turn offs for me. -No/poor editing. -Page formatting makes my eyes bleed. -The font tries too hard to be fun--especially for an instructional book. -pages feel cheap. -image quality is abysmal. - none of the information I was looking for and lots of information I wasnt.

Not helpful
Format: Paperback
This book is so basic it doesn't really help much in tips on identifying rocks and minerals. The photos are enlarged so much they are distorted and most photos are of the rocks cleaned and polished. That doesn't help with how to spot things in nature or where to look. I'm really disappointed. Also, Montana has a lot of cool rocks but all books ever speak of are sapphires and agates. I feel like I wasted my money. There are some helpful things but even as a beginner, most of the contents are known.
