What about the BG rebuild or freshen. I've got 2 that have been sitting dry since 2010 when I parked everything.. Any parts out there for seals and rubber parts? Hate to buy new if I can use them.. working well when parked.

Re: Electric Fuel Pumps...
 

I would think that even if someone doesn't sell the specific pn's for your BG pumps, you get some replacement ones from McMaster or a similar online seal outfit with some time using calipers to measure what you need. I have never had BG pumps apart though, so I could be off base on what the seals and rubber parts look like though...

Adger, I believe I've seen seal kits on racejunk for cheap money, I want to say $12.95. Worth a peek.

Ninja Fuel Systems sells rebuild parts for BG pumps and regulators. You can find him on FB or ebay. I believe Quick Fuel has the designs from BG and their parts interchange, I know the fuel filter elements will fit BG.

Allstate Carburetor also has all the Barry Grant seal kits and hard parts for pumps and regulators. I have used the Ninja seal kits in a BG280 as well as a 2 port regulator. The BG stuff is old but still good!

Montieth always ran his Hatari Qjet dead head. It was set up that way when I got the car so I tried and it worked flawlessly. Didn't see a reason to change. Ran at 6, 7 lbs.

Re: Electric Fuel Pumps...
 

Bruce ,I'm certainly not saying it hasn't been done that way successfully for years , most cars had a dead head system.
Technology and product advancements provided us with the options now available and having the return line is one of them ,especially with the newer high volume /pressure pumps that have flooded the market.

Re: Electric Fuel Pumps...
 

Just the regular is considered dead head as the pump is not just slammed shut but returning fuel there instead of another line from up front.

Any issues using a Holley return reg with a Aeromotive 1000? I just did a pump gas Wiseco 10:1 hydraulic roller engine for a 71 split bumper I rescued, plan to hot rod it on the street. I've already run a return +Holley Blue, Is Aeromotive durable for continual use, or is a Holley blue still the standard, anyone know? I'd like to put a quiet pump on this car. Just doing research. I've got aconstant duty relay on the blue, it screams.

The Holley blue regulator has a very small area. If you figure the area of the jets in your carb you need a similar or larger area in the regulator to get adequate flow. Otherwise the bowls start emptying as you go down track.
The lower float level could alter the A/F ratio.
The area also applies to Needle and seats.
2ea. .130 dia. N/S will out flow a single blue Holley regulator..
In the past when I ran Holley Blue regulators they were modified for increased flow.
If your a non believer take a blue Holley regulator apart and do some measuring.
The bypass regulator helps reduce air bubbles in the fuel and gives the carb a solid slug of fuel to get in the bowl. Most carbs don't care for air in the fuel & show it in performance.
How much HP are you making?.. HP requires LBS per Hr of fuel. Design a system that provides the correct LBS. Per Hour of fuel.
