Rear alky pump location

[TR Custom Parts]

OK, got a Metro fuel cell for the spare tire area and want to mount my pump. Have seen a couple of installations off the gas tank strap at the front of the gas tank.

I want to try something different than that. Was thinking of making a plate to attach to the rear bumper and a support bracket off of that up to the floor pan of the trunk. The pump would lie horizontally. Then I would run the pump feed line out the back of the spare tire well. Would be a straight shot from the sump of the tank to the pump.

Only thing I could think that would be bad about this would be the hazard of getting hit from behind with the pump right at the bumper but hey, got the same deal up front too right now. Other thing would be having to drill another hole in the car, no biggie to me.

BTW, nothing would be visible except the hose running down to the spare tire well.

Is it OK to lay the pump on it's side?? Wouldn't think it would matter.

Was originally thinking of mouting it on the frame horizontally on the pass side to the front of the right rear tire (Same area as the fuel filter on the left side) BUT you would have to run the hose up and over the rear before it got to the pump. Everything I have read seems to indicate that the pump has to be gravity fed somewhat. Was going to use some standoffs to mount the pump off of the frame to clear the metal lines that already run in that area. Just thinking out loud here.

You guys that DO have your pump mounted out back, how about some more detailed pics on how you attached it. I have seen the pics out there but they didn't really show how they were attached.

I think it would be cleaner on the rear bumper, just one of those decisions. I havent sized up a GN under the rear. So cant help you there.

No problem laying the pump on its side.

Got some 1/4 aluminum plate and will mock something up. If I like how it looks I will need all the stuff from you to extend everything to the rear of the car! Feed line to the pump will be real short that's for sure.

I wouldn't think any problem on the side. Just never upside down.

Just one thing Mark, what about the spare tire now?

Pretty long service run but prolly better then a long supply.

Think I would like to do a square one next to the spare.

Tell you a spot I like for the pump. On the inside passenger frame rail, right in front the rear tire. Check it out. There is quite a bit of room. I'd like to put my A1000 on the driver side one. That would be a sweet set up.

Read my first post!:biggrin: Was thinking there with some standoffs to clear the lines already on the frame but was always told the pump should be level or lower than the supply tank. Electric pumps are more of a pusher than a puller from what I have always understood.

When I was doing my install I contemplated hanging the pump from the rear bumper but any configuration I came up with either left the pump too exposed for my aesthetic tastes or left the pump input above the tank output.

The simplest and cleanest I came up with was on the front of the tank on the passenger side strap. I thought of maybe making up a bracket for the frame rail but didn't want to invest the time.

Not the best pics but they are all I have for the moment....

Not sure about that. If you notice, the outlet of the sump on the Metco tank is higher than you think. With the outlet on the sump facing the back of the car and a short line feeding the pump think it would be OK. As long as you don't run the tank real low the fuel level will be higher than the pump AND would think the g-forces of launching would help push the alky back to the pump??? Thoughts???

Oh, I'm not insisting that I'm right. I may have had tunnel vision and dismissed the bumper install too quickly. I just opted to make sure I'm well below the tank opening and, while I won't run the tank that low, I did install the tank for capacity so I didn't want to risk counting on G's to feed the pump when there's still a gallon available.

I'm sure you'll come up with something that works well and looks good. I just went for the "err on the side of caution" approach.....someone else had already done the same layout as what I ended up with, it is stealthy, and Julio said it should function well in this configuration. Good enough for me.

Didn't mean anything bad towards you. Sometimes the typed words don't come out right!

 

[incubus2432]

I didn't mean to imply anything either.......just saying that I certainly could be wrong. My mom says that I'm never right so odds are in your favor.

Read my first post!:biggrin:.

I guess I hit the reply button too quick.:redface:

One thing for sure, your using it and not having any issues. That in itself says a lot.

One thing is best way, another is a suitable way... another.. you work with what you have and make the best of it.

We're doing a kit now using a Metco fuel cell. Ill post up some pictures when we get it sorted out.
