Now you have carbs you might as well fit a standard mechanical fuel pump, on the block. You also no longer need the return line to the tank but I expect you have sorted that now.

I've changed to mechanical on my not-1800 not-E. All works well, but if I don't use the car for a month or so, I do have to churn it on the starter for 5-10 secs. I wonder if I had an electric pump it would avoid that.
Pic of my engine bay attached. Note the messy tangle of wiring behind the heater. POWEN has shamed me into getting rid of that this weekend. Bay.jpg |

If you are still using the original D jet pump I would get rid of it. If you manage to turn down the fuel pressure regulator to get a sufficiently low pressure for the carbs you would be by-passing huge amounts of fuel back to the tank wasting power and potentially frothing the fuel. |

A low pressure electric pump that is switched on in the run position for a couple of seconds prior to engaging the starter would likely eliminate your cranking problem. Or, the low tech solution is you could just drive the car more frequently . |

I do have the old D jet fuel pressure regulator that is screwed right down so unless I'm replacing the pipe work I'll leave it for now , Thanks for the advice Paul |

cooling, but when I updated the engine and changed to Webers, I changed to electric fan, which uses less HP to run. Glad you noticed my artistic trunking to the carbs! Revotec, who do the electric fan kit do some great scoops, one of which I have mounted in front of and the the right of the rad, with the trunking thru the hole where the old FI air input went I did consider a K&N airbox, but I don't think there's quite enough room Vs the inner wing. I need to neaten up the air exit a bit! Have also wrapped manifold in hi-tec insulation (not in a way that is likely to promote rust, he added quickly...). Oh, and 142, I do get out plenty! Drove to Velencia for the MotoGP last year... But November is sugar beet harvest in mid Suffolk and the roads are very VERY muddy. Everyone's car looks like a cow pat. 🚜💩 Last edited by sleek lemur; Nov 28th, 2020 at 20:29. |
