Thats DEEP @Ricko1966
Thxxxx

 

[Ricko1966]

Got you the name and number.

@Ricko1966 cool...send it boss!!!!
Thx

No, drainback or siphoning does not drain the carb.
What it can do is empty the fuel lines from the carb back to the tank. The carb can evaporate dry fast, even in a few hours. Most common causes of siphoning- weak pump valves, or worn, or dirt, and a bad fuel cap.

Can't happen in 1406 so irrelevant.

BS
That chinese carp has no check valve. Only Rochester's came with check valve fuel filters.

I can show you a dozen 1400 Chinabrocks that all leak down. We install bass check valves in them. The check valves wear out in 4-5 years and you have to replace them.
BTW did you know Chinabrock discontinued the 1400 series? NO Parts, no more, and AFB parts do not fit.

The fuel pump check valves are known to blow out due to FOD (foreign object damage).
Now and Then in Maine sell rebuild kits for all AMERCIAN made fuel pumps.

DO NOT put an eclectic fuel pump on a carbed engine. The machinal stock fuel pump will run everything short of dual quads.

I agree,I prefer a mechanical pump and have always told everyone that's what to run,and they will run 2x4s or 3x2s,But try buying one today,that has correct fuel pressure and is assembled correctly,it is more likely you will get a bad one than a good one..

Did they make a mechanical three-line fuel pump

Yes it was factory from I don't remember something like 1979 up.

My 79 K5 has 3 line pump.

I had luck with Carter pumps, all working without flaw. Fuel pressure ratings and real pressure is not matching most of the time. That's why I run fuel pressure regulators.

So your expierience also is that pressure isn't correct,without the use of an external presdure regulator

Yes. The pressure was always 2-3 psi higher as rated.
