Battery Cut-off and external inline fuel pump

[fastmonkeywheel]

Who here has a trunk mounted battery? I'd love to see your cut off switches look like. I got my Taylor box mounted yesterday in the spare tire well. It barely fit without having to do any cutting.

I don't think I'll see a ton of track time, but I don't want to limit myself right off the bat (maybe I'll catch the bug); so I'm adhering to NHRA rules.

Also, anyone running an external inline fuel pump? Where'd you mount it? I don't think my pump is going to last too long. It's a Merkur stocker. They had one in take to get the fuel out and then one inline to increase the pressure, I just have the inline one mounted to the trunk bottom (a little high from what I understand). It doesn't even hold the pressure when power is removed, so a new pump is in my immediate future. I'd like pictures of that too, please.

Any pics of your install?

I've got my battery in the trunk of my II. Mine is shut off with a rod that is pushed. When looking for a battery cut off switch, I went through one standard one, it didn't work because the alternator fed enough power to the ignition to keep the car running. I ended up going to speedway motors and got a switch with an alternator cut off included. http://www.speedwaymotors.com/Product.aspx?paging=yes&dept_id=247&display_id=2380

Here's a couple pictures of my battery box. I still need to run a better ground wire, hook up an inline fuse near the battery, and hook up an external cut off switch, and install the gaskets around the battery cables going into the box. But the box is in there. Does anyone know where I can get/borrow a lug crimper? I don't like using the screwdriver and hammer method for anything permenant.

I solder mine. What I do is heat up the end of the cable with a torch, and "tin" it, get some solder melted onto it so it's silver all the way around. Then I'll put the lug on, and using the torch, fill the remaining void (hole?) with solder so where the cable come out of the lug, it's completly full. I finish it off with a piece of heat shrink tubing, and that's about it. I haven't had any problems, though my friends have had issues with some other methods.

Ok, I have uploaded some pictures of what I have done with my car to get things the way I wanted them. First off, I had to remove the spare tire well, and then everything fit nice. You can see how my cut off switch is mounted. The fusible link is on the battery box, that's what that little tan thing is hanging off the box. I hope this helps!

I mounted my battery cut off switch in the tail light. I don't have any pic's but it turned out really nice and to my surprise, the II tail light is soooo deep the switch and battery cable cleared the tail light bulb! (all the tail lights work still).

My car has a carb, but might I sugjest a Ford Bronco electric pump. These units are in-line, pump a ton of fuel and have factory reliability. Joe Morgan with his 2.3l turbo Pinto ran 2 of these pumps in his 10? second nitros car!!! One would be plenty for most V8 or 2.3l Turbo street cars. The Ford Bronco pump is nice quiet. I used to work at a truck wrecker and these pumps last forever. Customers were always buying the used ones. They went for about $50.00 used. They are about $250 new.

not here to step on toes.... i run a carb, and aftermarket elec pumps are
cheap enough new. i think i paid $65 for the blue (preset) holley pump.
been there for 5 yrs now with no problems.
unfortunatly their arent enough full-size broncos out there anymore, and not all of them came with an inline pump.
some came with pumps in the tank, and some came with one in the tank and one in-line...yes i said that correctly some have two pumps. that is because they mount the inline pump under the drivers side seat on the frame (not in car)
and it wont pull enough being that far away, so it has a (helper)in the tank..
Holley specifies that their pump needs to be within 1 ft of the tank and not directly above it . otherwise it will not pull enough fuel..
Another good idea to do is put a fuel filter before and after the pump that way
it will keep the pump from sucking up any particles in the tank and the one after the pump is to catch any particles from the pump if it ever decides to fall apart internally..

btw the full size bronco with fuel injection runs about 60 psi, you would need to
bring that down to about 7 psi.

I agree with 2muchtime. I would think that the bronco pumps would be for an FI engine, and put out too much pressure for a carb. Joe Morgan can get away with it because his turbo pinto is fuel injected. What engine and performance expectations are you going for? I'm a big fan of Geroter fuel pumps. I've you ever listened to a holley vain style pump such as the famous holley blue pump, you know they're pretty noisy. Several companies make a geroter pump holley has the Volumax series

, and mallory seems to only make this style pump

I'm kind of in the same boat you are, I need to upgrade my fuel system, what I'm looking at is a Mallory comp 250 fuel pump, 5/8 fuel line, I need to add a fuel sump in my fuel tank, and return line, this costs $$$ so depending upon what you want to do, maybe all you would need to run is a small electric pump with a true 3/8 fuel line from pickup tube all the way to the carb?

Sorry guys, I thought we were talking F.I??? He mentioned "Merkur stocker?" Merkur xr4ti 2.3l turbo F.I???? Any-who if your talking carb, and your talkin' V8, I have a Carter HP electric and it works really well. Also consider getting a fuel pump safety switch from a late model ford. I got one out of a 97 Escort. The switch is a easy in line hook-up. The anertia switch has a red button on it, to re-set it if there is a false alarm. Gawd forbid that you have a mishap, it will turn off the fuel pump and prevent a Car-b-que

My car is fuel injected, I'm thinking of a Walbrol 255 lph pump. I've heard good stuff about them and they're only about $120 shipped.
