Which Inline Electric Fuel Pump & Regulator for Turbo

[66Comet]

Trying to get some advice on which inline electric fuel pump and regulator I should run for my 200 I6 with holly 2bbl and turbo? I have not picked out a turbo yet but I want to buy something that will work with a stock non turbo setup all the way to a 500hp turbo setup. I read an article where does 10 recommends a certain regulator that I have listed below but I am torn between the two or if there is something better. I don't need name brand price, I don't want to pay for name brand or for features that I don't really need.

Here is what I have found that seems to be in reasonable price point, not very sure on the fuel pump but I did see does 10 say something about wanting a pump that did about 30psi.

I am using the E8248 on my EFI 300. 36lb/hr injectors and has been up to 11.5psi boost. Fuel pressure gauge didn't show any pressure drop. Bought mine from Advance Auto, 2 days to get it.

Thanks for the help.

I went ahead and purchased the E8248 and the mallory 4309 from advance online since they have 15% off plus free shipping right now. I was more unsure about the fuel pump than the regulator.

There are features for both the pump and the regulator that you have to have for turbo'd and carbed. I assume it's a blow-thru?

1. Boost referenced so it'll increase fuel pressure 1:1 with boost pressure.
2. Able to go down to 5-6 psi when NOT "in boost".
3. Able to supply 5-6psi greater than whatever your "boost number" is. (10lbs. of boost = 15-16psi of fuel pressure)
4. Able to supply enough fuel at those higher pressures to keep the motor from going lean.

So long as they go do all of the above you'll be fine.
Later,
Will

Thanks Will.
The carb is a 2bbl holley that will have to be modified for blow-thru, I found an article about modifying the carb to make it blow-thru linked in one of the turbo articles here. I plan to do this and use the carb hat found on classicinlines website along with the 1.75" carb plate adapter. The 66 comet already had the 2bbl holley with an adapter plate but its the 1.5" intake hole. I don't really want to spend money milling my log or doing anything to it as it can get pricey and I would rather save the money for an aluminum head when I build a fresh motor.

Did you see any problems with what I ordered? I got the same regulator that you recommended some time ago to another member and I went with that fuel pump in the link above which according to the specs looks like it should work fine. I'd love to get get your advice on another thread I just started about picking the proper turbo...viewtopic.php?f=22&t=65123

We used the 4309 regulator for a long time. It'll work just fine.
Our first fuel pump was similar to the E8248.
So you should be fine.

Just make sure your fuel return line is the same size or at least very close to the same size as the feed side.
You want the regulator to regulate the pressure...not the fuel line.

Understood, I was thinking of running a new line for both the feed and return all the way back to the tank, this gives me the incentive to go ahead and do that. Thanks for the help.
