That's why I went for the filter king as well as its easy to fit a gauge to set then remove Sent from my SM-G975F using Tapatalk
It's unfortunate that they are so big but the convenience is hard to beat. To me, making these type of regulators without a port for a gauge seems stupid, but I'm sure there's a good reason.
...which is more than likely already regulated to the correct pressure. lol We (I include myself) buy these things in the wrong order - we should get a gauge first to check whether the pressure even needs regulating.
This is my pump, I wanted the filter king to prevent crud going in the carbs and increase pressure if required to feed them if they required it. Sent from my SM-G975F using Tapatalk
Just looked on JK and the electric pumps are 4 or 6 psi, so a little too high and they both mention the need to fit with a regulator, so fair chance it’s needed
I was just musing that my own one is probably not needed, my pump is a different type to yours. My problem is lack of trust. My pumps says it's regulated at 3.5 psi, I simply didn't believe it. lol. I've never opened the regulator right up to see because if it did sit and 3.5 psi I'd have to face the fact that my regulator is not actually doing anything. On the other hand I've never had any fuel in my oil, over fuelling at idle, or any of that malarky.
I hope you meant 3 psi, not 3 bar. A Facet cube pump plus a Malpassi regulator and a pressure gauge probably cost as much as a rotary pump that doesn’t need a regulator or a gauge or as many hose clips and potentially leaky joints. Why make something simple unnecessarily complicated?
The Bus has a Facet cube, it was on when I bought it, the cube puts out too much pressure on its own, it knackered the needle valves on my carbs, thanks previous owner, tho they could just have worn over time. You need a regulator with those cube pumps My pressure guage is inline, it's a decent one, tho I may now remove it given the system seems to be running properly, the whole fuel system took some sorting over my two and a bit years of ownership, including fitting a new carb linkage. The Malpassi with the in built guage port, are, as others have said, moohasive. I haven't had any leaks from the gauge, tho I accept the wisdom that it's one more thing that could leak.
Probably will do now that everything seems to be functioning properly, it has been very useful a number of times, when various bits were misbehaving.
Well, you almost convinced me I'm going barmy (actually quite a reasonable assumption), but mine is actually the right way round. 90º fitting on "In", 45º fitting on "Out" Should be able to do the same with yours?
