CNC FABRICATION 4-LINE-FEED 1999-03 7.3L FUEL BOWL RETAIN KIT- CNC-SD-7.3BRFK

All lines are made of mandrel bent 304 stainless steel and are double flared to ensure a proper seal. The kit comes with all necessary fittings for a complete install. No OEM fittings will be reused.  This system has been on our company truck for the past 6 years while running a set of 160/100 up to 450/400 single shot injectors with no issues.  If running bigger injectors than 180cc it is recommended that you upgrade your fuel pump or add another stock pump.

⚠️ IT IS HIGHLY RECOMMENDED THAT YOU USE LOCTITE 545 ON THE PIPE THREADED FITTINGS DURING INSTALL. OR IF YOU ARE VERY CAREFUL, YOU CAN USE TEFLON TAPE. IT IS CRITICAL YOU DO NOT GET ANY TAPE INTO THE FUEL SYSTEM DURING INSTALL.

You can also build your own pumps setup with filter heads and a regulator to save some money.  We recommend the Fuelab Prodigy pumps for more competition trucks, or the AEM 380lph pump for mild built trucks.@media only screen and (max-width: 600px) {.yith-wcbr-brands-logo a { display: inline-block; border: none!important; width: 60px; margin-top: -60px; margin-right: -15px !important; }} @media only screen and (max-width: 736px) and (min-width: 640px) {.yith-wcbr-brands-logo a { line-height:44 !Important; }} @media only screen and (max-width: 750px) and (min-width: 740px) {.yith-wcbr-brands-logo a { margin-top: -115px; width: 70px; margin-right: -20px !important; }} .yith_wapo_group_total {margin-top: -650px !important;} div#yith_wapo_groups_container { margin-top: -20px !important; } .yith-wcbm-badge-16953 { top: 203px !important; position: absolute; }
