Holley Blue Fuel pump Guys...I need your help

[Bumpin1ohmSS]

Hey all.. Ive been following the fuel pump location thread. Im wanting to setup a Holley Blue system for my GM Performance H.O. Deluxe 350. I cant afford the Mallory or Barry Grant setups right now. My H.O Deluxe has a Holly 4150 670cfm single inlet carb, Dougs headers, Edelbrock RPM intake. Turnkey crate motor. Nothin major-330 hp..Just a lil cruiser. BUT I wanted to set it up with an electric fuel pump. Im trying to get a handle on how to set it all up. Ive read that the return line systems are the way to go. The Holley system I'm looking at can be setup either way-with a return line or without. All I'd have to do is swap the Holly 12-803 standard regulator for the Holley 12-803BP "Bypass Regulator". Just wanted to know if you could take a look at my lil diagrams and tell me what you think, and if Im headed in the right direction....I have a tank Im getting welded up that has a dual line sump on bottom...All this is for my 1987 Chevy Monte Carlo SS

:!: The JB weld job is getting welded up correctly and pressure tested before installation :wink: :!:

Thanks for any help you can give...Been googling it trying to get armed with knowledge before I start wasting loot on parts not needed. Hope I gave you enough info on my motor. Here's a pic so you can see the possible plumbing. Holley sells a sweet bracket to hold the regulator for my style of carb. It mounts on the passenger side of the carb...I still want to use the summit filter/gauge setup also...

If I went the return line route, Id run the return line back to one of these lines on top of the tank correct?

Thanks for any help..

Your diagrams look pretty good to me. As far as the return line, I would run it into the factory feed line on the sending unit. That way you will be keeping your feed and return lines as close to the same diameter as possible. I am curious as to why you want to go to an electric set up though? As clean as your ride is and at the power level your at I would definetly stick to a mechanical pump. Much simpler and a LOT quieter.

where did you get that air cleaner set up from.

The air cleaner setup is cool looking but probably not the best place to mount the filters directly above the exhaust headers.

The other thing to consider is that the Holley blue pumps are usually pretty much junk. They have a bad tendancy of leaking and are extremely loud.

Where did you get the chrome upper radiator hose?

Got it from here...
Its really just for looks tho. I think the round filter that came with the motor works best. BUT I think this looks pretty sick. There's a lot of piping I still need to install. I want the piping to go all the way up front and tap into the cool air in the front air box. Filters and plenum nut came from ebay

You gotta excuse my ignorance. Please hang in there with me...I was thinking I had to run an electric setup because of the tank I'm repairing for the install. Everytime I see that sump setup, the car is running an electric fuel pump/regulator system. My Edelbrock mechanical pump is making a crazy clicking noise thats driving me crazy. LOL At first we thought it was an exhaust leak from the headers on the passenger side. We swapped in a new gasket and the noise was still there. Then I started looking at my fuel pressure gauge. Every time the "tick,tick,tick" noise happened, the gauge jumped right in time with the "click!". I picked up a stethescope (sp?) from Harbor frieght and did a lil poking around. When I touched the fuel pump, there was the ticking. I figured it was that lil rod in there. My bro has the same pump, but its nice and quiet. The other thing is that when I first fire the car up, that pressure gauge is all over the place. There's no return line to the tank. I looked around and saw the other metal line just sitting there open. Can a "return line regulator" be used with a mechanical pump? I know this will sound crazy but I love how that bracket for the regulator looks. LOL! Here's a pic. It would flow nicely with the other red parts and the whole theme Im goin for..

@FE3X CLONE--Thanks! I have a set of heat sheilds that actually do work. LOL! I'm having some work done to em so I can mount em a lil better. Here's a pic. There will be some other piping attatched to the front of the filters that will run up to the front air box..The ac comp is coming out also. Just gonna drop a delete pullley in there. I got that serp setup new for free and just slapped it on... The hose was made by a local shop. Told em what I wanted done and they fabbed it up...

Hose..@ pieces. Welded em and polished it up. I think he charged me $100. Lil pricey...There's some heat shrink tubing I'm gonna use that will really give it a clean look. Just wanted to make sure there wouldnt be any probs. I put the car on a 1000 mile road trip last weekend. Not a single drip. I might just leave the polished hose clamps..

Just to recap on the mechanical pump. Can I run a regulator on a mechanical setup? Or is that only used for electrical? I really want that bracket! LOL! I know it sounds crazy, but I like the look of it. Thanks again for reading thru all this and for the input and help fellas. Im learnin this stuff slowly but surely.. 😀

Interesting set up but I don't know if I'd have it at the bottom of the pan pointing to the back. That'll be the lowest point and if you backed into something like a parking block that may end up damaging it....another thing is won't all the dirt and/or grunge end up collecting in the box?

 

[Bumpin1ohmSS]

I see your point. But I swear every vid i checkout has the sump welded in the same spot. Im lookin at a clean Chevelle with pretty much the same setup on you tube. Hmmmm....

 

[FE3X CLONE]

Your right.

The sump setup is mostly for drag racers. When you accelerate, all the fuel sloshes towards the back of the tank which is the reason you want the pump outlets there.
Of course on a street car without baffling this might cause problems if you run the tank low.

Some mechanical pumps require a regulator so it just depends on what you get. I dont see any reason why you cant run it with any mechanical fuel pump.

1) trace the outline of your sump on the tank and then use a holesaw to do this.
It will capture every little bit of fuel you have, even in turns.

2) Lose the Holley and get Mallory 140 pump and return regulator mount on the fender away from the heat and vibration of the engine.Kinda like this.

3) Lose the extra filter after the reg

4) install the return in the tank like in your diagram. Weld a bung down low so the "returned" fuel is being shot to the back aimed in line with the sump.

5) have fun!
