Hey everyone, i was wondering what will be required for me to switch to a low pressure fuel pump for carbs. Do i plug off the return line or do i still use it somehow? Anyone have any specific examples of what they did with all of the extra lines after removing their fuel injection system? Thanks

(IMG:style_emoticons/default/popcorn[1].gif) ...Lots of ideas in this post Brandomc. here are a few more...1. You will need a low pressure fuel pump, one that is NOT for a fuel injection system. 2. you will need a LOW PRESSURE fuel pressure regulator, and a way to test fuel pressure. fuel pressure should be set at 3.5 psi. 3. you will need a good (metal cannister) fuel filter. 4. you should ensure the fuel pump is "soft" mounted w/ rubber soft mounts. you will need a ground wire to the pump body. the "hot" wire should have a fuse. 5. there are many places you can mount the fuel pump, but THE ENGINE BAY should not be one of them. 6. I cannot suggest strongly enough to run NEW FUEL LINES for the entire system. (the fuel lines are about 35 years old) 7. NOW is a good time to pull the gas tank, and clean it out, especially the fuel strainer/screen filter. You will need to plug off the small line,(inlet fitting) which is/was the fuel injection return line. 8. you will probably find that 5/16 '' fuel line,...( or 8 mm) fits the carburator fittings best. 9, use s.s.hose clamps. 10. install a new metal fuel line through the chassis. finally, If you will do all of this at one time you can eliminate a "fire hassard" as a cause for concern for quite some time. routine maintenance checks are necessary for any fuel system. murray (IMG:style_emoticons/default/popcorn[1].gif)
