Hello got a question for you all,
I re-fitted the facet #480532 pump my car came with:
http://www.glencoeltd.co.uk/facet-480532-red-top-cylindrical-fuel-pump/
Maximum fuel delivery 45 gallons per hour. Maximum pressure 6 to 8 psi
However it's way too much pressure and overwhelms the carb bowls with petrol dripping out of the carbs onto the manifold (didn't detect this before, because the float valves were seized
(that'll teach me to clean and service the carbs but hey, they had been bodged beyond recognition, filed needles, the works)
Anyway got suggestions? Flow rate psi?
Was thinking this might work:
https://www.pegasusautoracing.com/productdetails.asp?RecID=2698
Maximum pressure 2.75-4.0 psi. Maximum flow 34 gallons per hour.
#477060
I'm not sure what kind of pressure and flow rate I should be looking at, nor why there's such variation on the spec, from 2.75 to 4 seems a lot.
If it helps engine is an L28 with suspected cam by a "Richard Wardle" or at least that's what the plaque on the rocker cover says. I have to say this thing revs like hell, but no wonder it was running so darn rich
S'cuse learning curve, I make telescopes so have some engineering knowledge but I know next to nothing about cars
Cheers guys, Nick
