Fuel Pump

[neebles]

Anyone ever install one of these?

Manifold Spacer, with Pulse Fitting.
Aluminum spacer with pulse fitting can be used either in front or behind carb. Run your fule pump without getting oil in it and/or having to drill into the block.

When used behind carb, dyno testing has shown up to 0.2 hp improvement due to longer intake tract. Improvement is over entire RPM range. Even if you don't need a fuel pump, this piece adds power.

Im still thinking about running a fuel pump,....It looks like this would do the trick...There werent a lot of details on the web site, would it work on a stock carb (6.5 blue clone)? would there need to be any other mods done for this to fit?

looks like something I need, what website?

about half way down the page...
What are your thoughts on installing it?

That would work well. I use a jetski pump on my kart, and the pulse pump only worked so so off a crankcase hose, testing with a vacuum/pressure gauge showed very weak pulses, but I drilled and tapped my intake and put a gauge there, lots of strong pulses. Now my pump is connected there and it works great.

 

[kazkepox]

it seems like it would work fine, just make sure everything is nice and tight when you put it on.

Ok, so Im ready to run my fuel pump set up, how should the pump be mounted? I havent seen any mounting brackets or anything for the round pump, just the rectangle pump. I know it should be mounted vertically, and not on the block itself, because of the heat. If anyone here is running a pump, how is yours mounted?

The pulse line must be between the intake port and the carb to get a pulse. Wont work on the air filter side of the carb.

Ok,noted, I was asking more literally about how the pump itself needs to be mounted, or if it matters. Also, for a floor mounted fuel tank, does it just bolt to the floor, or is a mounting bracket needed for that?

That pulse line looks like a pretty good place to put a nitrous jet in...

here's where i installed my pulse fitting

 

[Kaptain Krunch]

Mounting angle shouldnt matter but i would mount it flat.

 

[neebles]

Flat like horizontally? So the the pulse fitting is sticking up or flat to the back of the seat (just an example so the pulse fitting sticks out.....Im not worried abut where to run the pulse fitting in my motor, as I have ordered that manifold spacer above. Im just worried about where to mount the pump itself, and the gas tank....

I think he means he'd mount the pump flat. I don't know.
NR racing also has a mount kit for the fuel pump.

Heres another way to do it. IF you can see it.

 

[neebles]

Thanks, thats what I was looking for. Now, as far as a floor pan mouted fuel tank, do you just drill holes and bolt on, or is there a mount for that as well?

I am not sure on this, but I think it bolts to the floor pan.

Your doing the same thing I'm going to be doing. I'm going with a floor mounted cell.

It looks to me like they bolt to the floor pan..

Yeah, thats the tank im looking at, I have it in my BMI "shopping Kart" but havent pulled the trigger yet.

Thinking about this too:
ARC Throttle Kit - CNC machined from 1/8" aluminum plate. All the parts for the throttle mechanism that do not come with an engine are included (cable and jacket sold separately). The throttle mechanism maximizes the travel at the foot pedal giving you more precise throttle control. The plate is pre-drilled to accept the Mikuni fuel pump as pictured here (sold separately) so the pump will accept the existing fuel hose provided with the engine. Does not include cable

I am sort-of looking at that G-Man tank aswell. But I may make one myself, or see if I can find one on some other vehicle.
I can't really help you with the throttle stuff. I used the stock junk on my GX160 and now I'm doing a 22mm Mikuni.

Edit: You do have the same first name as I do, same spelling too.

Here's how and where mine is mounted:

...and it works great!!! The coil, CDI box, and fuel pump are all mounted on a form fitted plate that's held to the seat with 3 studs, so I can remove 3 nuts and the whole thing comes off. That came in handy for re-setting the timing, because the seat has to come off for that. Just take off 3 nuts and set the plate aside, take off 2 nuts and loosen two sliders and the seat comes out.

 

[neebles]

Thats sweet!, thanks!

Ok. I got that manifold spacer in... I took off the carb, put the spacer on, then the carb...It appears that the bolts arent long enough to be able to put the air filter back on, I cant see how to pull the bolts out, and replace them with longer ones either. Any suggestions?

Edit: there is also a black plastic piece, that would go between the carb and the motor, does anyone know if its ok to just leave that off, especially since the spacer is going there now?
