I have a roadster with a 392 hemi and a WC 3-D intake manifold with three new big 97 Stromberg’s. Would like to know who makes a low pressure regulator and the best place to mount it. I don’t want to mount on the firewall looking at the front of the motor off the bolts for the water pump, I need to make a bracket to hold it. I was gonna mount the filter right off the regulator and feeds into the fuel rail with a gas pressure gauge at the end of the rail. Your thoughts
I mounted mine low on the firewall to keep that sanitary look. The take off with the ball valve services the pressure gauge on the dash. I valved it in case of a gauge failure or leak. The bracket also has threaded provisions for the throttle pedal
A Holley 12-804 regulator is 1-4 psi adjustable and looks like the one nochop has on his firewall. I've mounted them on the front of cylinder heads and they do fine there. Your water pump mount should work.
Did you even look for a regulator, or were you depending on others to do that for you ? Took me about 20 seconds to find your "low" pressure regulator. If you don't like that one, I'm sure Jegs and Summit have others that may suit you. https://www.jegs.com/i/JEGS/555/159...TDpSNlPzy43iKjpYz2jI2vGCpEtgbnv7kBrjE2g&gQT=1 Your car, mount where YOU...like. Firewall, fuel rail... Mike
I wanted to firewall mount mine but didn't want to deal with the vibration isolation issues of the lines coming to and from the engine driven pump. Wil end up mounting mine off the carb studs so that the reg sits between on top of the intake ahead of the carb. Looks meh but works. Thankfully I can close the hood. I think a front mount would be just fine and give a clean look.
And you may be moving it next summer when you start boiling fuel in the lines. Fuel, like revenge, is a dish best served cold. I mounted the roadsters on the frame rail under the car where no one has to look at it but it is still serviceable...with a jack.
Nice setup. I'm wanting to do the same thing. I have 2 of the WC 3-D intakes.one is drilled for Rochesters and the other for Strombergs. You'll have to let me know how your 392 runs with the big 97's when you get it going.Can't decide which carbs to run.
You can always put the regulator after the carburetors in a return line to the tank. The carburetors will receive full volume of the fuel pump at the set regulator pressure. The return fuel line bleeds off the pressure and sends unused fuel back to the tank, as a bonus, no vapor lock. Never run a fuel line into or through a drivers area! If you must have a pressure gauge inside the cabin, use a pressure ISOLATOR. Also, NEVER use solid fuel line if there is any chance of movement from mounting location to mounting location, frame to body, frame to engine, or engine to body. For best safety practices, follow NHRA rules.
I never mount fuel regulators, blocks, or anything to do with fuel on the firewall. Occasionally I run the drags and the car wont pass tech if fuel lines or devices are firewall mounted. I have a couple on the frame ahead of the engine, and one mounted off a bracket towards the front of the engine. I use Holley regulators with one input and two outputs. One output gets a pressure gauge so I can adjust pressure and watch the gauge as I adjust it.
I've never had a heat related issue with my regulator mounted on the front of the engine. I use a piece of aluminum bar stock with holes to dissipate heat and space it off the head so it's hanging out in the breeze.
