hoping for some help

[benno440]

some people saying i do need a pump and some saying i dont, getting more confused now. should i ask somewhere else?

 

[Propwash]

Well...you're gonna need a pump unless you have other means to get the fuel to the carbs. As far as a regulator, yes you need one. It states that as well on "Race pumps" website for that pump. Question is; are you going to run a deadhead type regulator or a bypass regulator with a return line? Already tossed IMO, so hopefully some other members can help guide you as well.

 

[benno440]

already got pump and regulator man, pump is installed just trying to figure out the regulator

props right benno. me, i would talk to race pumps, explain the set up and do what they say. nough said
ooops, good luck:headbang:

I gotta hit the snooze pad, but here's some reading from a thread over at BigblockDart you may find interesting Benno...

benno just call the pump makers.weather or not you can run a deadhead system will depend on how good there pump recirculates the fuel within its self.i am sure they will recomend the return line system,but i think your question to them should be"will you be ok running a deadhead system with there pump."that is a huge pump,why so much pump if you dont mind me asking?running two small eddy's shouldnt need anywhere near that much pump.

I'm with 67 Coronet. Why the huge pump with 2- 500 cfm carbs? Looks like overkill. 50 psi and $319.00? Thought this was a street/strip car. Money best spent somewhere else.

 

[RustyRatRod]

no life is not hard, just going off what you told me in previous posts rusty is that if my car never came with a return line i would not need one, as it is already vented.

- - - Updated - - -



yes it has a single vent that runs upto the gas cap.

yeh dfeinetly no problems with fuel now haha

If I said it like that, I was mistaken. I think what I had in mind was that you didn't need a VENT if it had the factory vent already there. But it will need a return line of some sort. Can you run without one? Sure, but it will run much better with one.

I've been wonderin that all along myself.

i know the pump is overkill but here are my reasons, and with money spent elsewhere i have absolutely nothing else to buy for my car except a hemi but 315.00 is a bit off $25000.

my motor is now a 505 i have a big cam i have changed the fuel line and pickup to a 1/2" setup as i was told its better to have it there now then change it later if i need it.
i couldnt find any pump that has a 1/2" inlet/outlet
i was told on here that there is no mechanical pump that would supply enough fuel for my engine and i didnt want to run an electric pump cause there noisy, you have to run extra wiring etc etc. so i found this pump.

and anyway it only pumps what it can it wont overfuel it etc.

this is my reasons guys.

Running a return line really makes your life easier. Especially in the summer. I would tap the line into your filler neck so it does not mess with your float.

 

[RustyRatRod]

You don't have to find a pump with 1/2 inlet and outlet. Most HP pumps come with 1/4" pipe inlets and outlets. That's already bigger than 1/2" fuel line. You adapt down from there.

As was said you need to know if it is a return line system regulator. I use an electric pump and mounted my regulator on the fenderwell as you can see here. Mine does not use a return line but I have bought a regulator that does use return line as I may go to that type later. With the return line system the fuel is kept cooler since it is always flowing and that helps alot in the real hot humid summer weather if you run this cheap pump gas we have now. I do run on pump and had some fuel boiling problems this past summer with this pump gas they make now. Many still use the deadhead system and it works fine as thats all we used back in the 70's. But if you live where it gets real hot in the summer then the return system is a good idea. Good luck , Ron

"this is my reasons guys."

Benno: I understand your reasoning. Of course everyone has an opinion and I wish we had kicked around your question more as to what pump to run earlier. My opinion is that the large Carter mechanical pump would work just fine for your motor. Running the 1/2" fuel line provides an adequate supply for any kind of carburetion you might run in the future. If it's not too late, I'd return the Race Pump and get the Carter for 1/3 the price. Run 1/2" (-8) from the pump to the regulator, mounted on the inner fender or a bracket on the intake, and 3/8" (-6) to each carburetor with a minimum of bent fittings. Whether or not to run a return line on a street/strip car is open to debate. Personally, I would wait to see if there is a need before doing it. It may be a non issue for you, as it is for me. Still having fun?

No mechanical pump that can feed those two eddy 500's? LOL......I have a Eddy Dual quad set up with two 600 CFM carbs i'm getting rid of. It was ran off a run of the mill Carter performance pump with 3/8" line. Absolutely no starvation issues.

If you did want a mechanical pump with 1/2" NPT, the Clay Smith would work for that and for half the price. Old George from Clay rates this up to 1200-1300HP. Would that cover ya? LOL

[benno440]

never even heard of that pump otherwise would of gone that, too late now, oh well, i am starting to realise much to my dissapointment i will have to run a return line it gets very hot here in summer but i was not going to drive in summer as my car does not have aircon and 45 degrees celsius dry heat is bad enough.
race pumps said if i dont run a return line there is a 50% chance in summer i will get vapor lock and they said just to use a bulkhead fitting at the fuel tank. i am not sure about this.

not that we have determined that i should probably run the line can anyone recommend/help with what i will need to do this. here is what is currently in car.

68 charger
stock fuel tank, 1/2" pickup 1/2" aluminium line to engine bay with a 1/2" filter then 1/2""line to the pump, then i guess 1/2" line to regulator then 2 x -6 lines to the carbs.

thanks for the help guys

I swear to God, I'm ready to give up. I gave you a diagram. I told you where to put the regulator and how to use it. If I could afford to come to Australia and do it for you I would cause I've always wanted to see it.

i appreciate that rusty but your diagram is very basic, i dont know what size run to line and how to feed it back into tank ( what parts will i need to do this)
sorry for being difficlut i have had my car for 2 years and car is almost on the road and now am going to have to modify **** again just getting frustrated.

cheers for the help guys

 

[RustyRatRod]

As I said before, it doesn't matter what size line. Run 1/2" if you have enough. It will keep you from buying any more. You could run schedule 40 sewer pipe return line the way that diagram is, because it uses the regulator as the return restriction. It will only flow what the regulator allows.

X2. Even a Clay Smith mechanical (optional over the Carter) would be overkill.


And I can testify to how well Ron's (383man) car runs with his simple set up.

 

[benno440]

just read 68 models had only one vent line that ran throught the trunk up the filler neck to the cap, 69 and later had multiple vent lines for emissions, will this change anything?

i saw someone welded a an bung onto his tank for the return line will this work?
