|
|
My mechanical fuel pump died today. I'm thinking about ordering the purolator pro# 42S Part # 1008 from Appletree for 44 bucks.
Do I need to get a pressure regulator too or will the 3 PSI advertised be ok for a Weber 32/36 DFAV?

I have a mechanical with an electric backup as required for racing class 9. I dont know about the pump you are talking about but I was talking to someone at FAT and he said that 3lbs is the max. They insisted that it is a must to run a regulator.
I know its not much but that is all I got. _________________ “It takes a big man to cry, but it takes a bigger man to laugh at that man.”

Thanks guys.
The filter was plugged, replaced, buggy started. I still want to go electric and will include a regulator in the process.
This is the greatest forum ever. I dig my sand rail better than any of the bikes I've had. |

My buggy came with a low pressure electric pump on it and It runs great....no issues. It's nice if the car sits for weeks/ months, turn the key on for a few seconds and the carbs top up with gas. Then it starts right up. |

$20 and you get a new mechanical fuel pump.
Don't have to worry about the pump running on after an accident. It shuts off with the engine. _________________ Society is like stew. If you don't keep it stirred up, you end up with a lot of scum on the top!--Edward Abbey

So being new to this VW thing I was prompted to go out and see if I had a regulator in in-line that I somehow could have missed.
As I figured no regulator and I am running the Purolator pump that the op listed. If I remember correctly my pressure is about 4 lbs.....
What is the purpose of the regulator? Consistant fuel flow?
Why do I need one?
Forgot tot mention, I'm running dual IDA 48's. |

It's my understanding that too High fuel pressure is as bad as too Low fuel pressure. Run what the carb Manu. recommends. |

OK then. I will need to get a regulator. The buggy was running crappy at the end of our last trip and I just replaced the element in the fuel filter and I have a tad over 5psi from the fuel pump. I thought that's what it was usually at.
I did a little research and it seems the dual 48's should be at 3-3.5 to run properly.
I have read the chrome ones with the dial are junk. Any recommendations on a capable regulator that won't break the bank? I'll be having to purchase some AN fittings as well so it's going to get fairly expensive.
Sorry if I hijacked the thread.........it all seems to go together. |

After a bit of surfing, I found some Holly Fuel regulators for about $36. The come in a couple of PSI ratings, choose the one for your carb. Most of the popular parts houses have them. I found them with minimal trouble. |

Saw them. My local supplier has them as well and that's probably what I will go with. |
