Thanks Baddad, I'm switching back to carb just haven't figured out how to change the screen name! Are you running 140mph on the topend with the stock front suspension? brave soul!
Yea, but it's been rebuilt. And far more stable than my 06 GT Mustang was at that speed. Rack & pinion steering isn't all it's cracked up to be.
Joe Dirt has a used 12S and a Carter fuel pump for sale on his site. http://www.joedirtfabrication.com/
I have this unit on my car just to prime the system if I haven't driven the car for awhile. It isn't really " mounted ". I placed this pump right where the fuel sender tube originally connected to the tube running to the front of the car. It fit perfectly where the original hose was! It is held quite securely by the hoses, so I saw no need to mount it. It is very quiet. I just connect it to my side marker light ( parking lights on ) when I want it to run. It saved me one day when my mechanical pump failed! The mechanical pump draws right through the electrical one when it's off which is great! Here's what I'm using. It is a Purolator - Facet pump for carburetted engines. If I remember right, it's a 5psi pump.
that's where I mounted mine. it's the stock switch that came from the donor car that I got the E-fuel pump from that I put in the tank...also ran off relay... it's at the bottom of this pic...
In the first post you said you were thinking about mounting the pump under the drivers seat near the frame. Thats where I had my Holley blue pump mounted for 15 years. Never had a problem until the pump needed a reseal. It pretty much gravity feeds to the pump and it sucks the fuel just fine. I rana fuel pressure gauge inside the car and never had a drop in pressure.
update on fuel pump location I thought I would contribute to the board for a change and post some pics of the fuel pump mounting on my 74. It is mounted on a plate with the pre-filter between the driver side inner quarter panel and the frame rail. Pics tell the story.
I like the work on that! However it looks like the fuel pump will be directly above where my exhaust pipe will be. I like the way you mounted the pump upside down. I never thought about doing it that way. I guess there's no reason not to mount it in that orientation.
Just a small word of caution holley red,blue and black pumps are not designed to be inverted once fuel enters the electric motor you could be in for a potential bad time they only use a tiny o ring to seal the shaft. take it for what its worth If it is mounted sideways or upside down, and the pump seal fails it will leak fuel into the electrical motor and cause a fire hazard.
John, due to the offset gas tank in the mavericks I "plumbed" both exhaust pipes to exit on the passenger side. Exhaust on one side and fuel on the other side. Makes sense to me. JoeD, you bring up a good point. I'd like to explore the idea more. The holley blue has a weep hole that fuel will exit if fuel begins to leak past the shaft. Mounted in the upright position fuel runs "under" the motor and would be forced up past the shaft through the weep hole. If mounted upside down fuel is running above the motor so if the shaft leaks fuel will still likely find its way out the weep hole. Either scenario isn't good. I agree that the pump may not last as long in the inverted position but perhaps shaft seal failure would be detected a little earlier in the game in the inverted position. Second, if fuel leaks past the shaft into the motor I assume it would wash out the lubricant and cause failure fairly rapidly. Also, I assume there is not oxygen inside the pump so no ignition of fuel? As a note, I also read that you should not clamp the bracket around the pump to tightly. Also, I think a good number of holley fuel pump owners have them mounted in some orientation other than upright, often horizontally. Thoughts? UPDATE: called Holley and installation upright is important! Way to go JoeD. I installed it inverted to create more clearance with the leaf spring. Changing the orientation will not be a big deal. Thanks.
