I told you guys that I was having troubles with cold starting recently and how the Boss would fire up and then die out while in high idle then maybe fire up again and die and then it wouldn't start for a while.

The fuel pump is dead.

I am in the process of rewiring my front end and after testing everything the only part not working is the fuel pump. I checked the ground and re-grounded it elsewhere. I have power all the way to the unit, unless the hard wire coming out of it is bad.

I am looking at a new fuel pump and I know that we talked about this over on the Yahoo site last year sometime and I remember something about fuel pressure being around 6 or 7 lbs. I found a Holley Red pump for about 95 in Jeggs and a Marine grade pump for 115. I also found a Carter pump for about $60. Are either of these OK? Or do you recommend something else?

Hossman,

I run the Holley Red with no problems. You don't need a pressure regulator with this one. I left my stock pump up front in case I need a spare.

I have been running a red Holley for 3 years and is great for my bike. 35,000 miles and love it.

Hoss,

Wag & I put the Carter rotary vein 4070's in ours.............very quiet, run cool and easy to mount with minimal fabrication.....see Wags post on his site. No regulator required and they flow about 72+ gph free flow.

Thanks Adrian.........I have to admit that I sometimes have a hard time keeping up with the crowd I hang with (and who kindly let the 'old man' tag along)...........but I beleive that once I settle down and get off the 'edge', I'll be on the downhill slide........not ready for that yet :lol:

Thanks Grumpy, Adrian, Wag, Chris and you others. I should have thought to check out Wag's site first. Very good site and getting better. I think that I will be trying out the Carter pump.

Tim mentioned mounting it in front of the battery. Is this to keep the heat down and to avoid vapor lock? Is there any other reasons to mount it here? Seems like it will be easier to get to if it has any problems in the future.

Hoss,

We wanted them upright, away from the heat as much as possible (not attached to a heat transferring point) and easy to get to. They say a rotary vein can be mounted on its side, unlike the diaphram style that are stock, but we just thought verticle would give us better life.

We just made flat plates and extended them from the cross rail, towards the engine.....With the stock battery it was snug, but with the 925's in there we had a bunch of room.

I ordered the Carter pump and it should be here in a day or two. In the mean time I was trying to plan the installation. I plan to move it closer to the battery to avoid the heat problems that have been addressed in the past. Also this will allow a vertical install rather than the horizontal install. Someone mentioned that this rotary vane pump can be installed sideways though. But getting it away from the heat can't hurt.

Anyways, as I was going through the fuel system, I found an item located in line between the main tank and the reserve tank. It says pump on it and has electricity to it. I think it looks to small to be a fuel pump. Does it control the switch between the main and the reserve tank? Does everyone have one of these?

Hoss,

I'm almost certain it is your switch from main to reserve but I'll withold confirmation and let one of the experts chime in .

Hoss , what you have is a Fuel tank selector valve. It it for switching the fuel flow from the main tank to the reserve tank . I assume you have a toggle switch to switch from the main tank to the reserve tank . The older bikes had a shut off petcock right on the reserve tank that you could open or close manually . The selector valve took the place of this petcock .

Thanks Jack and Chris, I suspected it might be that. My bike has the fuel selector switch and the petcock on the reserve tank.
