Came across the standard problem with many of the purchased components - they don't come with fittings ......... The fuel flow meter has to connect to the 1/4" fuel line - but no fittings supplied. After many other shops, I ended up at a drag-racing shop to get the fittings. No driving around time is included in the cumulative build time.
Used a couple of "P" clamps to clamp the metre to the engine mount - then fitted the fuel lines and fire shrouding.
Now need to find a fitting to connect the fuel pressure meter - even the drag shop didn't have that ....
