OK guys, I am having trouble mounting my CFP. I have no clue where to mount it to! Frame rail is the only place, but it would hang too low for comfort, plus making a skid plate wouldnt be helpful, especially if i hit a bump. So my question to you guys, where did you mount your pump?

 

Mine was mounted on the back of the drivers bin area. I used the bracket that came with the carter pump, and bent it so that the pump sat properly upwards, and the the bracket could be bolted up with a bolt and a nut inside the cabin area.

 

Hey Jeezus,

How ya been? Here's where mine went:

The second pic shows ground clearance is no problem.

You can move your cut and check valve higher up on the frame rail, that will give you enough clearance. If you mount it on the backside of the bin, you will need to make a bracket so the pump sits vertical and add more sound deadening or stiffen the bin wall as the bin will transmit more pump noise than the frame mount will.

I have mounted them both ways. Made a fancy little bracket for the backside of the bin, then added an 1/8" plate to the inside of the bin to cut down on resonance.

 

I have done the relocation of the check and cut valve. Being that the carter is a rotary vane pump it can even be mounted in the engine bay.

 

Hmmm interesting, I was under the impression that since the purpose of the pump is to push (and increase pressure) the fuel to the carb that this would be a bad idea. Wouldn't it dramatically decrease the life of the pump using it as a fuel puller rather than it's intended usage?

I remember I posted about doing a similar thing when I was looking at mounting my carter, but turned away from it.

 

I didn't think the pump would be happy pulling that far. I know the Holleys that are basicaly the same pump, are recommended to be mounted as close to the tank as posibble, same for the Mallory Comp sreies, but they are grotor pumps. Not sure what the difference is between the rotary vane and grotor is.

 

I think another factor that pushed me to mount the pump near the factory position was in the fuel pump instructions. I believe it did mention to mount the pump as close to the tank as possible.

 

Ouch...ninety degree fittings right on the pump itself...;eek:...the best mounting place for the Carter would be, of course, in a trash can.

 

What. Am I invisible here?

IIRC (and I always do ) And I quote: "The best location for mounting any electric fuel pump is in the rear of the vehicle. The inlet and outlet of the pump must be mounted below the lowest point of the tank. This is necessary to allow for an adequate fuel supply. The pump is designed to push fuel and not designed to suck fuel out of the tank."

Its been great, finally able to put my car together. intake and exhaust will be done, but the fuel pump (the first thing I start with) is giving me so much trouble.

in your pic, did you remove this completely or did you mount it somewhere else?

 

As long as psi and flow volume is adequate, the 90* bends will make little difference. The banjo bolts on the top of the carb are 90's, as are the supply lines to the Holleys and every other aftermarket carb I've seen for a rotary.

 

Uh yeah. The "fuel cut-off"? I moved it. To a box on the porch.

First, we survived being born to mothers who smoked and/or drank while they were pregnant.

They took aspirin, ate blue cheese dressing, tuna from a can, and didn't get tested for diabetes.

Then after that trauma, we were put to sleep on our tummies in baby cribs covered with bright colored lead-based paints.

We had no childproof lids on medicine bottles, doors or cabinets and when we
rode our bikes, we had no helmets, not to mention, the risks we took hitchhiking.

As infants & children, we would ride in cars with no car seats, booster seats, seat belts or air bags.

Riding in the back of a pick up on a warm day was always a special treat.

We drank water from the garden hose and NOT from a bottle.

We shared one soft drink with four friends, from one bottle and NO ONE actually died from this.

We ate cupcakes, white bread and real butter and drank koolade made with sugar, but we weren't overweight because ...WE WERE ALWAYS OUTSIDE PLAYING !

We would leave home in the morning and play all day, as long as we were back when the streetlights came on.

No one was able to reach us all day. And we were O.K.

We would spend hours building our go-carts out of scraps and then ride down
the hill, only to find out we forgot the brakes. After running into the bushes a few times, we learned to solve the problem.

We did not have Playstations, Nintendo's, X-boxes, no video games at all, no 150 channels on cable, no video movies or DVD's, no surround-sound or CD's, no cell phones, no personal computers, no Internet or chat rooms.......

WE HAD FRIENDS and we went outside and found them!

We fell out of trees, got cut, broke bones and teeth and there were no lawsuits from these accidents.

We ate worms and mud pies made from dirt, and the worms did not live in us forever.

We were given BB guns for our 10th birthdays, made up games with sticks and tennis ***** and, although we were told it would happen, we did not put out very many eyes.

We rode bikes or walked to a friend's house and knocked on the door or rang
the bell, or just walked in and talked to them!

Little League had tryouts and not everyone made the team. Those who
didn't had to learn to deal with disappointment. Imagine that!!

The idea of a parent bailing us out if we broke the law was unheard of. They actually sided with the law!

We had freedom, failure, success and responsibility, and we learned HOW TO DEAL WITH IT ALL!

If YOU are one of them . . . CONGRATULATIONS!

If not, mount your fuel cut-off switch higher on the rail.

Be safe.

Peace,

DD

 

LOL. You and I grew up in the same era and we both survived quite nicely, thank you. That is one of the best rants on how things have gotten out of hand that I have read in a long time.

I did keep my cut and check valve however.

 

i mounted in the exact same manner as dublydurty, and also ditched the fuel cut.

 

That's funny, because I have a co-worker who's y'all's age Trochoid and DublyDurty...

(Well, he is possibly older. Should retire soon.)

Anyhow, he refuses to drive his Opel GT because the fuel tank sits in the floor of the trunk, inside the car.

 

Hell, look at the 60's pickups, Ford and Chevy. Fuel tank is mounted right behind the seat, inside the cab. Some of the older Vettes are the same way. Tell your friend he needs to swap a rotary into GT, his life will change.

 

Dude that rant is blog material right there. brb... done. LOL!

 

Lots of information and photos on this install right here: https://www.rx7club.com//showthread.php?t=529605

Nice rant DD (I ditched mine too)...

 

I should tell you I didn't create that rant. I'm just passing it on from another "survivor". I don't know who the original author is, but I thought it was worth sharing.

So what exactly does that check and cut valve do?

 

It stops the flow of fuel if you flip your car over...

 

If I flip my car over, I've got other more important problems to worry about.

Besides, wouldn't the fuel just come out of the filler or the vent lines or something?

And if the car is indeed upside down, aren't the pickup tubes ABOVE the level of the fuel since they're at the BOTTOM, which is now the top of the tank?
