[King Tito]

well for those who dnt know me i got a 96 Tahoe who a carbed 350 vortec. i was driving the truck yesturday to the shop cuz i couldnt get the alternator charging...well i noticed that the psi gauge on the fpr(fuel pressure regulator) was marking over 15 psi's well this morning i opened the ignition to try to re-adjust it. wen i look to the gauge it was over 15 psi again. wen i looked down the carb was overfilled wit fuel.. i mean OVERFLOWED!! so i took all the fuel out. dried the manifolds and open the ignition again the fuel was seeping threw the carb's seals... i kno i got a stock fuel pump that puts out 60 psi's this is the fpr that im running.

Tito if the truck has been sitting for a while with a carb sometimes the floats stick and then it will overflow like that, take the top off and take out the floats and get new ones if it is a holley or an edelbrock you can take the floats out and actually hear the gas in them when you shake them check it out I bet this is the problem!

[Pugsley]

and get a barry grant fuel reg and you shouldnt ever have a problem.

na pugsley everything is new on the truck about 2 months old. i but them from the store.. i ve been hearing good things about this barry grant fpr.. i just dont think i can afford it rite now

Sounds like the fpr is just letting to much fpressure leak through , the first thing that came to mind was the floats sticking also . I have run those holleys with issue an also know alot of ppl who have done efi to carb conversions with no issue.

I used to run them on my mustang with my holley blue/black pumps without issue.
1 for car , 1 for nitrous . Id try readjusting it , its a simple design not much to go wrong inside.

i did try to readjust and it wont adjust im going to take it apart i believe that the diaphram broke.. i was told that fpr i have is no good for the amount of psi's that the fuel pump is pushing

tito are u runnig the stock pump for the injection??? Those are 2 high psi for a carburetor you either need to put a manual pump on or put external with regulator.
