Has anyone had any problem with their Malpassi fuel reg leaking fuel from one of the bolts on the top? Mine is pissing fuel from the top of the reg, from one of the little bolts around the edge, any one else had this problem?
What regs do people run? Standard turbo reg or aftermarket? Noe ill have to get the stupid thing dynoed again, dam car it never ends!
I want to find a regulator that has two adjustments and a proper differential
pressure gauge - ie One that measures pressure between manifold and fuel rail.
The two adjustments I am looking for are:-
a. Static differential pressure
b. Rising rate multiplier (from say 1:1 to say 1:2 or so),
In relation to pressure issues, this post might be relevant:-

Niche what is it with you and rising rate regs? lol All your ever doing is increasing base pressure in correspondance to boost pressure. It works and the car doesnt lean out and you can use less injector cycle for same amount of fuel at the higher boost pressure. The way my fuel system in the LS1 is setup is, jack pump, swirl tank, 2 High Pressure pumps, -10AN lines into a Y through the two rails, two returns to the reg then a single -10 return from the bottom of the reg. Boost reference line from inlet manifold to port on reg. So when pressure gets above 62.5psi reg starts to open and control the pressure, when it has boost on it say 10psi, reg wont open till 72.5psi. The fuel pressure gauge is on the rail side of the reg.
I use Aeromotive FTW but Magnafuel Sard etc etc are all good. Alot of the good ones come out of the same factory
Some original photos have not been recovered yet.
Because Malpussys are so cheap you have to assume that the parts used to make the fuel reg were made by little johnny noodles in the back of some asian sex slave sindicits shed putting 300 together in his 18 hour shift.
It shows aswell, ever turn your ignition on and get that awful screaming noise from the diaphram vibrating its tits off. (if you record the screaming noise and play it in reverse its actualy a hidden message from little johny noodles).
The fuel reg itself looks like crap. And if youve had your car off the road and no fuel in the reg you can say by by to the diaphram cause that **** will dry and split on yoooooooo candy asss.

Because many regs that say they are rising rate just are not...!
The only way to be sure is to use a differential pressure gauge and *not*
rely on the gauge that is part of the reg - because it is plumbed wrong...!
Its amazing how stupid some suppliers are and whats worse lie to the public
and plumb a gauge in the wrong way - its a form of deception - I hate that.

So what style of reg would you call mine? whats 250kpa about 36ish PSI? So what your looking for is that the pressure differential between the manifold pressure and the fuel pressure is maintained at that constant state regardless of manifold pressure??
If i stick 6psi in it and the fuel pressure increase 6psi over base pressure so say VL pressure of 36psi and when there is 6psi boost that pressure in the rail should be 42psi in the rail isnt that correct? Thats what my aeromotive reg does anyway.
1 PSI fuel pressure added to 1 PSI of boost pressure.
how is that not a 1:1 rising rate. fuel pressure rises according to boost pressure, and decreases with vacuum
all seems logical to me. ive never quite understood your theory behind FPRs niche.
technicly niches right i just cant be bothered trying to explain, ill leave it up to nichy to explain.
Take the malpassi off, burn it, get a sard or sx reg and be done with it

I see what he means.. Im just stirring the pot. Its all a perspective point of view thing. My regulator to Niche or you rusty would be a maintaining rate reg as In it maintains the pressure differential between rail pressure and manifold pressure where as a rising rate would increase injector pressure in relation to manifold pressure increase.
