I have a good deal on a Ron's Gold belt drive fuel pump but have no experience with this particular brand. How about some feedback from you guys.

I have run the gold pump for three season without hassle. If you run alky though, be sure to drain the fuel out of the pump and lube it up with marvel mystery oil, so that the seals dont sry out front the alky. When I called them for a spare belt for the pump they said that this is the number one issue that customers call with after letting them sit and let the alky dry up in them all year.

There pumps work great !

works fine here, have 2 of them, find a local parts place for the belts, i got 12 spare belts for $44 from our local place, when the parts trailer at the track wanted $29 a piece..lol

Fortunately we have a racing store nearby and I asked them about the gold pump and here is what they told me.
When the IMCA mods were an affordable class with not as much engine as they have today the gold pump worked just fine. Today with the late model engines in the UMP,s the gold pump doesn't put out enough volume and they suggested to use the black pump ($500)
Is there any truth to this.

Yeah if your running a 900hp LM engine in your Mod, but if your like everybody else and have a 650 to 700hp motor you'll be fine.

This is a flat out lie the GOld pump will put out more than you can ever use for a modified we use one in a UMP car and have Never had a fuel volume issue.

Go on to www.poske.com they sell the gold pump with a kit that comes with all you need to install it, and a decent price that is where mine came from.

I dont know who you might be dealing with locally but they know very little about belt drive fuel pumps.

Now if you need a monster fuel pump for 900 horse Rons makes those also, but the gold is more than adequate for a modifieds need.

When I talked to Rons before buying the pump they told that anything above the gold would be too much for my application.

the folks at Rons are helpful give them a call if you want more info.

I have runthe black one for 2 years no problems at all. I use the BG diaphram bypass with the jet inside for the idle pressure and it works great.

How far can you saftly go (HP, engine size, etc.) with the Edlebrock 1711 before you need a Belt Drive setup such as this one?

I heard 850 hp is the cut off, that is "i heard". No idea of the real truth of things, but that came from a good source.

"I dont know who you might be dealing with locally but they know very little about belt drive fuel pumps."

Keep in mind, there in buisness to sell stuff. If they can get more of your money they will. Not saying its right, but its usually the case.

How about a block mounted standard pump? What is the cut off on them. I have a friend with a 421 alcohol motor with a 15 psi block mount pump. He hasn't run it yet. I wish him good luck.

We just built a 600 to 625hp 360 cubed small block, roller cam and the whole nine yards. The engine guy says the mech pump will be just fine.

415, depends on the power i guess and the size of the carb, but i think it should be ok.

Think i would coast around out there a few laps and watch the fuel pressure, to see if it drops to low when you accelerate hard, under load etc. Watch that temp gauge as well until he is confident its getting enough fuel.

Maybe even run a few laps, easy and come in and check the plugs to be really safe.

I wish we would just stay with gas, engine builder dont wanna hear it. Old friend of ours thats doing us alot of favors, so i wont argue with him, yet anyway.

We have run block mounted mech. pumps for years and they work,but the pulsation from the heavy sprung pump causes a flooding problem at idle most of the time.We have been running the BG barrel valve by-pass to get the fuel pressure under control at idle 3 lbs and 8 to 9 lbs above 3000 RPM but it still floods if we idle too long. I have tried every kind of needle and seat and float known to man. Same results. The C&S guys at PRI told us to run an air chamber in the line to the carb or on the end of the fuel log and this would cure the problem by dampening the pulsations. Gonna try it this year if it ever stops raining out here.

dman what do you mean by air chamber?i have mechanical with bypass it seems to work ok except it blows a ton of fuel through the bypass ran it shortly it did have a big drop in pressure when i flooredit but didnt seem to affect performance but worried it will blo by seats when letting out of gas or sudden slo downs .want to buy belt drive but as other car has no problems but cash poor when i bought new car lol

The air chamber C&S was referring to was their in line plastic housing fuel filter mounted upside down so it traps air in the top of the filter housing.Mount it at the back of your fuel log or anywhere on the pressure side of the pump.This will give some cushioning effect to the pulsation (they say) like the air chambers that are used in houses to keep the pipes from banging when you shut off a faucet abruptly.
It seems worth a try. I'll make my own.

The pulsation dampener idea is good although you may have to keep an eye on your fuel pressure at the gauge. You may experience a drop in pressure at the gauge due to the pulsation dampening device absorbing some of the fuel pressure. Your fuel pressure to the carburetor should remain the same, you may get a false reading at the gauge?????

I run the rons gold pump. They have two different ones with different flow rates (-0 which catalogs list up to 650 hp and -0 1/2 which catalogs list from 650-950hp). I sent mine back to rons to get freshened a couple years back...and I inquired how much HP that the pump was good for...and they told me 725 hp with the smaller flow gold pump. Being they are the makers of the pump, I would believe them...if they thought I needed more, they would've sold me a pump for $300-600, but instead they rebuilt my pump for $99.

On a side note, they have discontinued the gold pump...they have replaced it with a billet vane pump, which flows the same. It can be seen at http://www.ronsfuel.com/gold_vane.cfm and is just a matter of swapping pumps, everything else bolts up. I'm putting one of these on my new motor.
