I will try to explain it the best i can .you can use a bypass reg and be done but they are exspensive compared to 2 cheapo holley regulators.

you connect the supply line into the first regulator in the bottom port then the return in one of the out ports and the other out port goes to the other regulator .you set the first regulator to 14 psi and put a restrictor of some kind in the return line like a nos pill or something similar.you set the other regulator a 7 psi . no creep no erratic pressure solid 7 psi...The key is the right restrictor in return line .....

none of my cars have this set up....but i have done it in the past and my freind rocks his everyday with that set up.I will try to get pics of his set up

 

I had a single bypass regulator on the 86. With that one I found it ran better (Lasted longer before it stalled out) if I upped the fuel pressure to 6 PSI. Anything higher and fuel spit out of the top of the carb. So if I had a second regulator slowing the return line then it should have worked better?

I'm not trying to be a dick here John,.. I know it seems that way sometimes,.. but this isnt one of them. I promise. But why then,.. when I used a regular non bypass regulator and dead headed the fuel at the carb that it was worse? (Stalled out before you made it into 3rd gear).

I would really like to see how you did yours. Because I am notorious for tossing a carb on a Mustang the second I lose my patience with EFI. If I could save a few bucks over the way I (normally) do it,.. I would use your method in a heart beat.

Wanna' save a few buck's? Use a manual fuel pump and get a stock Distributor from a carb car. I have a couple if you're wanting a drop in and go. Also have a new Holley manual fuel pump sitting on the shelf and a couple of old regulators that work.

 

Its mechanical,.. not manual Jeff,.. (chuckle).

They wont work on a roller block with out changing the timing cover to a pre 86 cover. The boss is blocked off on the later covers. That and I'm not sure if roller cams have the lobe for a fuel pump on them??

I had one on a '93, '89, '88, '90 and '91... Put one on Joker's '87...My brother is running one on his '94 5.? and his Windsor Bronco. Seemed(s) to work just fine without changing out the TC.


Racen50, lemme' know if you're interested in the part's dude.

 

Thats strange,.. the boss on my son's 1990 cover is there,.. You can see where it would go,.. but its blocked off. The one on my 93 was also as was the one on my wife's 87. (Shrug) Is there any way you can take some pics,.. or is is possible that they are not HO blocks? Or maybe the covers have been replaced? You know me Jeff,.. I like to see. Not saying your a liar or anything. Just that if I come across anything in the future,.. I like to know what I will be up against before I buy anything. Thats all.

Edit:

I just grabbed the camera and was going to take a pic to show you what I mean and its raining out,.. baaah.

Hurst

 

Hurst i will stop by my buddies and take a pic for you

 

What do you do,.. just notch out the boss?
Will they work with roller cams too?
Because if so that would simplify a lot. Holley Blue pumps are noisey little bastards.

Hurst

 

This is what I am talking about,.. where would you put a mechanical pump? The boss is blocked off. No machined threads either.

I must have had some of the rarest shit around then. Those pic's are long gone dude. I wasn't too much into documenting shit back then, just wanted to go fast.

When I go back down to the shop this week to weld my intake, i'll crack a couple pic's of my brother's Windsor and his other motor with one.

The way I see it, if a MECHANICAL fuel pump can fuel a 500ci Cadillac motor, it can fuel a small block too.
