Belt drive fuel pump rear mount fuel cell

Just curious how many people use a belt drive pump with a rear mounted fuel cell in a door car?
Do you have any problems with it? do you need to go with a bigger pump if the cell
is in the back?

Fuel pump (Mechanical or Electric) is always better located behind and below the tank to have Gravity and G forces help feed it. Pumps work better at pumping the fuel than sucking. Restrictive fuel filter or clogged vent will make it worse. If possible you could put a small surge tank up front and feed it will electric pump.

Good thing is most mechanical pumps are much bigger than you need so still may do the job.

I believe Banjo has been running like that for years and his works well.

Bottom line is I would try to do it right and get tank up front but if you simply can not for some reason it will probably still work you just have less room for error.

Curly is ded on Rear mounted cell will work in lot of situations. It does not always.I burned up 2 80A pumps before moved cell to front and never had another issue after that. Personally would not run rear cell with belt driven pump

Most I have heard that it worked with had carb and not MFI.That might be a issue that makes difference.How ? beats hell out of me.

I've been using a belt pump and rear cell (alky carb) on my 6.40/10.10 car for 20 years. It's been great.

As was mentioned, I don't think it would work with injection, mostly because you need a free-flowing return.

I know lots of bracket racers that run a rear tank with belt drive pump with a alky carb and works great. It will not work well with MFI unless you run a electric pump and a front surge tank to feed the pump.

I did fail to mention it is a carb. 6.20 to 6.30 door car.

I have run belt drive pumps before, but it was on a dragster and a door car with front mount cell.

Been looking at apd pumps. Might give them a call and talk to them.

bo laws once told me that anything with a 60' slower than 1.320 a belt pump and rear tank would work. dont know how they come up with 1.32 60' but i can say that my car with a belt pump and rear tank my 60' was 1.32 to 1.34 (somewhere in there) and it worked fine. now i will say that on the leave the fuel pressure would spike to 0 but would come back once the car got moving.

I've seen a lot of people pull their hair out trying it.

Big variable too if it does *seem* to work.

Have several around here with belt drives and tank in the rear running 5.70s on alky
Just make sure the tank is higher than the pump.

I've seen plenty of 5 second cars with this combo. I personally use this setup on our truck but it only goes 6.20's/30's.
Pump is mounted low, tank is higher.

I also run that setup, been 1.26 sixties to tripping the sixties with the rear tires and fuel pressure is always solid.

I know people are successful with the deadhead setups, but prefer the return style setup. It may not make much of a difference, but in my mind, the fuel is always moving, which would counter the g-forces.

Good luck

I have talked to a few people that said they had problems with internal bypass style. They said they had better luck with the pump with regulators on them.

It just not possible to put a fuel cell up front in my car without making major changes. Not willing to do that to put a belt drive pump on. I can see where it could be harder for the pump to get the fuel up there with the cell being in the back but my cell is pretty high up in the rear, so it should gravity feed pretty good. It does do big wheelies sometimes, so that will have to be something I take into consideration.

Thanks for all the comments. I appreciate it.

Absolutely return style regulator. It the OP is running a carb that also helps.

G forces and physics. Why fight it?

There is no pump, mechanical or electric that suck worth a darn. However they all can push a lot of fuel.

Carbs are the setups that Seem to work fine. It's not IF but when with a MFI you will get burned with a front pump and a rear tank

If you run a mechanical pump and must have a rear tank at least step up and move the pump to the rear using the Waterman cable drive.
