Short story is I'm adding the Facet fuel pump to my bike where the shutoff used to be. Looked around here the last day or two for a picture of how youse guys running these have installed them. I've gone blind reading everything I found but have yet to find a picture. Does anyone have one they can post or point me to one? I'm more of a visual person...

Second question is this: I did find one picture online of an install on a ST1100, but I'm not understanding it completely. I'm attaching the picture so you can see. To me it looks like the fuel is going from the tank to the pump to the filter to the carbs. I'm not understanding the red hose coming from the T past the pump. Looks like a vent tube but wouldn't gas just shoot through it? Does that T-part have a one way valve in it? Is it really needed? Do I have the fuel path wrong?

I just don't get it...Help?

I have no clue what the red line is doing, sorry.
His supply line loops back and into the front side of the pump. (front of bike) then comes out the back or left side and on to the filter. from the filter it feeds the carbs.
I had good luck with these.
 
does anyone have the facet pump part number, and do they draw fuel through the original fuel pump. I would like to buy one
too have a back up.
 
I can't recall what pressure I have, they offer several. If you can find what the OEM puts out just get the one closest to that pressure.
They do draw through the OEM pump assuming you leave it in. I did and had no issues.
 
That picture is from my bike. The red line went to a fuel pressure gauge that I had mounted on the handlebars. I was having fuel starvation problems so I instrumented the bike to investigate. I used a Facet 105 pump drawing through the OEM pump. Once I found the fuel filter was the problem I remove the Facet pump.

Thanks for the answer Rick, that helps alot. I stared at that picture a while trying to figure out what the mystical red hose could be used as. I was no where close...

SteveP - I ordered the Facet 40178 I believe. 2-3.5 psi, recommended in several posts here on the forum.

It will be a few days before I get it all done, this thing called work and family have been keeping me out of the garage. I've got the tupperware off ready to get at it. Planning to replace the battery, install the Facet, and install an auxillary fuse block under the seat to run some of my electrics. Luckily the beer fridge is stocked, just waiting on time to get in there.
 
This is a great thread. Thanks for the explanation, Rick. I was confused too.

Since lipSTick is currently undressed, I grabbed a couple pics.

The number on the lower right is not the Facet part number, the correct number is stamped on one of the mount tabs, 40106 in my case. FACET web site says that's a 7.0-4.0 PSI max/min which is probably high. I think the correct recommended number is the 40105, 4.0-3.0 PSI. I bought this one across the counter at a small auto parts store in N.E. Texas a while ago when the stock pump quit. The fuel filter (left end of the installed pump) was included.

Bike seems to run fine and is returning ~47 MPG at highway speeds. I'm gonna add a 40105 pump to STick as the after-market in tank pump is too high of pressure. This is a cheap 'n easy fix to the OEM pump, much simpler and cheaper than OEM replacement.
 
Hey George, I keep getting an "invalid attachment" message when I click on the links in your email.

Is anyone else having this problem?

Can you repost them?
 
Same here, you may want to send him a PM
 
Just saw that failure, I'm getting it too. Trying again.

Okay, this is weird, can't find'em on my 'puter either. Ah, well, I'll reload.

There, found'em. As noted before, the actual part number is stamped on the mounting "wing", not visible on these pics.

(To make a long story even longer, investigation on Saturday found the "fuel cut-off relay" was defective on lipSTick. I cannibalized the relay off STanley (nee ReSTored) and the oem pump magically began to work again. This is very odd, as I had tried it with direct battery power when she first quit last summer and got zero flow.

Anyway, the Facet is powered from my FuzeBlok thru a mini-toggle switch. The OEM pump (actually, STick's original pump with about 250,000 miles on it) seems to be working. Easy to test with the Face turned off at the toggle switch. I'll do that today. Gotta go down to the post office and send my RoadCrafter off to Aerostich for a full refurb and new zippers.

In the meantime, I took STick (with an after market submerged pump) for a short ride yesterday. She hasn't been out'a the garage since I got back from the east coast back in May. She started right up on the first push of the button and didn't miss a lick on a 10 mile ride around town. 210,000+ miles right now.

Oh, and I'm gonna go get me another facet (a 105 this time) to add to STick. I don't trust any fuel pump any longer. I'll wire it the same as lipSTick with a toggle in line, it'll just sit in reserve 'til/if needed.
 
I have been using the Facet 40178 now for the last couple of years. The unique thing about this particular Facet Pump is that it has an anti-drainback check valve that the other Facet pumps do not have and its pressure rating is pretty much similar to the stock pump. It has worked beautifully so far. I simply removed the stock pump from its internal mount and plugged the hole that the pump came out of with a disc cut out of aluminium. this way the pickup screen remains intact as well as the internal check valve.

I like your wiring George. I think I will add a toggle for the rebuild of the 97.
John, if you see this you may want to think about it too. May not be any issue but with a switch you/we can use it when and if the OEM takes a dump on the road. Being that they are aviation pumps, it may not be an issue to have them running all the time as they would in a small plane, so the choice is yours.

Dan - I missed it, but did you put your Facet in the tank or out of the tank?

In the tank?? I didn't know they were submersible, never considered it. Mine have hung from the air cleaner where the shut off was.

Couldn't hurt I suppose. I just assumed the OEM pump was out of commission, didn't realize the Facet was running in line with it. If that's the case, then a toggle is a good idea to keep it in reserve if needed, like you said.

No - mine is mounted outside - I made a bracket and mounted it to the air cleaner mounts for the vacuum cutoff valve that is now gone. I did not want it rattling around and possibly chafing wires etc.

George, how did you go about testing this relay to determine it was faulty?
 
My friend George can add to this, but the Fuel Cut-off Relay test is on page 21-5 in my Honda Service Manual.

My test was simple: put multi-meter on the correct wire at the fuel pump, start bike (plenty of fuel in the carbs), see 0VDC. I then pulled the relay off STanley, used clip leads to test, saw volts at the appropriate place.

I already had lipSTick stripped down to install new HID headlights, so simple to pull the plug off the old (failed) relay and plug in the replacement. Tested for volts again at the fuel pump and found all good. Short test ride yesterday proved the fix.

Odd thing, when she first failed, 5 miles west of the Wabash river on US-50, the fuel pump would not run with direct battery volts,,, so I still have no long term confidence in that OEM pump. The Facet will remain in place, with the mini toggle switch set to OFF. Until needed again. (The current OEM pump in lipSTick is STick's original, no with maybe 250,000 miles or more.)

Recall, I put the Facet in two years ago, somewhere east of Dallas, to be able to continue a long trip.

Yesterday, I picked up another Facet, 40105 this time, at the local NAPA store. It's not the familiar "cube" but now black and (apparently) cast aluminum housing instead of stamped sheet metal. Box sez right on it, "Not intended for aircraft use". ~$60.

I'm gonna install this on STick, along with a functioning OEM pump. She currently has one of the in-tank submerged after market pumps I bought a couple years ago. I think the pressure is too high tho the physically look and operate similar to the OEM Mitsubishi pump.
