I have a Holley blue electric fuel pump that I would like to install in my 75 v-8 conversion. I am trying to decide the best location to install it.
Choice 1: Install it near the stock location up front in the trunk mounting it on the wall that encloses the gas tank facing inward towards the trunk for easy accessibility. Gravity fed from tank and regulated up front also so the lines going back to the carb are only pressurized to 5lbs. Wiring is already there. + easy install and wiring is already there - lines pressurized length of car + cooler in front trunk, even with radiator, than engine compartment Choice 2: Install it in the engine compartment somewhere on the passenger side. The pump would be gravity fed the length of the car and then pressurized and regulated in the engine bay. I would have to run a wire for to power it up. + gravity fed so lines are not under pressure in tunnel - not sure if pump will work as well trying to pull rather than push - hotter in engine compartment What would be the better approach? Thanks Attached image(s) |

some info: http://www.914world.com/bbs2/index.php?act...3&hl=holley http://www.914world.com/bbs2/index.php?sho...;hl=holley+blue http://www.914world.com/bbs2/index.php?s=&...st&p=575721 Leave it up front if the power and mounting hardware is already there. I'm a fan of recirculating even if you have carbs.... up front... (IMG:style_emoticons/default/agree.gif) +++cooler! just a crazy, maybe overkill way but maybe you could pre-regulate it (in front) down to ...say... 10 p.s.i. before your final regulator at the carbs if you have concerns. i'll bet you have an extra regulator to loop the excess back on a front reg. you are looping (or returning) the fuel from the rear? i had a complete pump/reg set up from a parted out 914 i wanted to run on my 69 ranchero but i ended up selling the truck first. mike Great links and pics...that helps. Mike, I like your idea of pre regulating the pressure say to 10 and then another regulator in the engine bay to kick it down to 5 and push the excess back to the tank with the return line that is still there. Sounds like it should work. I do have a regulator now, but it's only an in/out...no third port for diverting the excess. If I used it I wouldn't be able to recirculate the fuel. neo914...I saw you had an aluminum 90 by your water pump...where did you get that and did you have any problems with all the pressure coming right out of the pump and going into an almost immediate 90 turn. Seems like I read that the pressure would be too great and you would blow hoses there. If it works, it would fit much better. Thanks guys! |
