I am considering a front accumulator tank due to a rear-mounted cell with a belt-driven fuel pump. Or, may relocate the cell in front of the pump. I expect the "Roughly Square" S-10 will run in the 6.20 range, 1/8 mile. Around 1.35 60'
For those of you running this setup, let me hear from you. [PS, APD Methanol carb]

I have three door cars with rear cells and belt drive pumps. My vega being the fastest at 1.27/5.77 we have no problems even running 1/4 mile. I choose to filter after the pump for better supply to the pump.

Larry I have a 1.5 gallon front surge tank on the s10 but I am running Ron's Injection not a carb. It was the best option for me because I did want the extra weight out in front of the radiator, plus the expense of building the mount for it
I know several running internal bypass belt driven pumps with a rear mounted tank and alky carb without any problems. If you can keep the pump at or below the bottom of the tank so it gravity feeds I cant see a problem. I would run a #10 line from the tank to the pump and make sure the tank is well vented

I also have an 3 quart Moroso accumulator mounted between the crankshaft and the radiator. I had to reduce the length of the belt drive mandrel (vacuum pump and alternator belts) to clear the tank. It was actually a puzzle figuring out the correct shims, bolts, belt sizes and brackets to get everything to line up again.

Not a lot of fun, but everything lines up.

This has been argued few time here. I am in the front tank needed. Maybe other have gotten by w/o most being carb. Not sure why different but seems carbs don't need it.

I burned up two pumps on my nova before I installed front tank. Never had problem afterwards.

I do believe if have pump mounted low and below tank level it helps too.

option 3, put the pump in the back and run a cable to drive it. (pretty pricey) https://www.alkydigger.net/cat...man_Cable_Drive.html

Because carbs have bowls that give it lag time if the pump slows slightly or has a small hiccup. Lots of people running belt drive pump with tank in the back and carburetor. You do need to really pay attention to not having restrictions to the pump.

I Had two pumps go bad with rear tank, No restriction between pump and tank if anything had too big of line for need. I figure carbs have less demand on pump and take on less fuel which keeps pump wet even if hiccup as stated.Injection on other hand has more flow although good amount returns.If hiccup pump can have dry spell and at 4000 pump rpm minor amount of time could start wear since fuel is only thing lubricating it.

Never had bracket car with data logger till now and not sure a small dry spell would even show. I do think having return to bottom of pump would be good idea also. Can not say about other pumps but know Enderle have always been bad about eating cover if go dry at all.

larry no matter how many have pumped from the rear my opinion is build a custom cell to fit in front.when i do this i can normally find all the aluminum i need at jennings for pennies.that way you can build it to fit the space you have.no fuel issues that way

Put tank up front….
