Just curious. What's your guy's opinions of belt driven versus mechanical (stock location) fuel pumps?

We're building a new motor and need to decide which way to go.

TIA

i think the cost factor is why most guys use the a factory type mechanical pump. the belt drive pumps are pricey.

I run a six valve Holley and it works good. It needs to be rebuilt every year and you need to carry a spare with all the fittings on it. The mechanical gear pump is better, but it cost alot and they break and wear too, so you need a spare. In any case a fuel pressure gauge I consider a must to monitor the situation from week to week.

I have ran the KSE tandem for 7 years without a failure. I've changed the seals and orings twice. The initial investment is high but I consider this the best money we have spent.

I agree with Old Racer. I have been running my KSE for 6 yrs and no problems. It is more money initially, but remember that the pump runs your fuel pressure and your power steering. You'll probably spend $300 on a Sweet power steering pump and bracket. So, when you consider this, it's not quite as much money. Also, I know of 4 guys that were having fuel system problems blowing up motors, and once they went with the KSE, their problems were gone. You won't have to deal with regulating idle pressure with regulators or bypass systems. This is the only way to go and I recommend anyone getting into alcohol make the initial investment on a KSE. Look around, you might be able to pick one up used, and they're not expensive to get freshened up. When you take one apart, you'll be surprised how simple they are, probably why they work so well.

i've run the kse tandom for 4 years without doing anything. best way to go in the long run. it is using power steering fluid, and i was thinking the seal needed to be replaced. is this something i can do or it it a factory service thing?

I had the same problem, if you look into your cell you will probably see that your fuel is milky. Yes that is your power steering fluid. I contacted KSE and they know of the problem. The new pumps have a different seal. Rebuild your pump just o-rings and seals (very little money) and your golden.

Are you guys running front or rear mounted belt driven pumps. I like the sound of rear mounted. Those of you with front mounted pumps do you do anything special as far as shielding to keep mud and rocks from knocking the belt off.

Also, just an FYI , we're building an alcohol motor.

What kind of lashup do you use for rear mounted pumps.

TIA

I have been running a BLP front mount fuel pump. It has built-in regulator and does not need a return line to the fuel cell. I have been running it since '96 and really like it.
