Fuel Pressure
Can anyone with a speedster or a similar type of car tell me what kind of a fuel pressure regulator you use to get the proper pressure to the carb from an 6 volt electric fuel pump?
Also, what would be the pressure at the carb? Somewhere around 1-2 P.S.I.?

Re: Fuel Pressure
1-2 psi is about right. I have a 12 volt system but I don't have a regulator on the pump. The one I bought is a low pressure pump that has a 4 psi max pressure. I have used it with two different carbs (Zenith A and B) and have not had any problems with leakage.

Re: Fuel Pressure
those common dial type regulators are not very reliable. The most popular in the Classic Car Club ( many of whom are converting to avoid vapor lock from ethanol) are the Holleys 1psi-4psi range. On an A, 1-1.5 psi is plenty.

Re: Fuel Pressure
Thanks. I have seen some 6v pumps in the 3-5 P.S.I. range, but I thought that might be a bit high.
I'm just thinking relying on a gravity feed from the bed on a pickup or a huckster might not be such a good idea. Don't want to run into fuel starvation issues. I'd stick with the original tank, but I have no idea how to get it really clean of all the rust in it, or how to keep it from rusting more in the future. Working on flushing it out, but it's a slow process, so I figured a 12 gallon poly tank would be the way to go.

Re: Fuel Pressure
I run a 12 gallon poly tank in the bed of my late'31. I use a 12v pump and a low pressure Holley regulator set to 2 lbs to 2 81 Strombergs.
