I am new to rotary's and I have a 83 Rx7 LE and When at about 70 mph I floored it and it got to about 80 before it started to sputtter almost like it was out of gas. I just filled it up 30 minutes prior. The oil level was at about halfway so I filled it up and it didn't happpen since then. I was just wondering if it had to do with the carb which was recently rebuilt. Anyone know what happended? Thanks

Well the stock fuel pump is too small for even stock. It's just the way it is! Probably just got a little starved when you floored it.

So I basically just gotta get a better fuel pump. Shouldn't be to difficult.

It may just be the fuel filter. I would start there even if it looks good.

Remo

ok thanks, Fuel filters are a lot cheaper then fuel pumps.

What Chris said. Look for the biggest filter you can find.



If you do have to get a race pump, my suggestion is a Holley Red. Little pricey, but rock solid reliable for me, and I've put them on 3 cars and heard no issues there, either.

I used a Carter universal, and left the fuel pressure regulator on that came with the holley blue. The red may be better than the blue, but I will never buy

another holley pump. It lasted a total of 3 months before I started smelling gas. It started leaking between the motor and pump. I put the Carter

in and have never had another problem since. No flooding or starvation at all. I don't take mine to redline, but around 6k to 7 it has never run out of fuel.





I did have to monkey around with the fuel lines a bit, but nothing too major. The worst part was cutting down the hard line over the axle to avoid

a rubber line kink. I hooked it up with the stock wiring and heat shrink connectors. All of the original pump mounting plate is gone and no longer needed. The

holley's are incredibly loud and could not be silenced. I had the bottom of the bin sound deadened, stuffed fiberglass insulation in every place I could. Nothing

worked, and I was almost glad it finally kicked the bucket. The Carter makes half the noise, and can only be heard at idle with the radio off. All other times the

radio or engine/exhaust drown it out.





The Carter pump, available as a universal pump at many auto parts. They will probably have their own part number derived from the Carter number. The one I used is the top picture. Get some right angle fittings before you start the job, you'll thank yourself later, lol.,,,,BB

On the Summit racing site. I didn't pay near that much. I guess it pays sometimes to work at an auto parts store, hehe.
