fuel evaporating

Have posted on this topic b4, but need some final advice please.

My pinto engined kit car seems to lose all fuel from carb after standing for a week or two, and needs a lot of cranking to get fuel through for starting.Have tried non return valves and things - but to no avail. Following advice from last postings, I have got hold of an electric pump, and tried it "in series" with the mechanical pump (both sides tried - I.E.- b4 mech pump and after) but mech pump cannot suck / blow through elec pump when it is switched off. I don't want the elec pump running all the time - just a short burst to prime the carb as in the circumstances above.

So.I am considering fitting it "in parallel" with the mech pump. Thought I would use "T" pieces or "Y" pieces in the fuel lines, either side of mech pump.

Does NE1 foresee any problems with such an arrangement? Also, does NE1 know where I can get suitable "T or Y" couplings - or should I make up them myself (have a small lathe and lots of bits of ali /brass rod /tube)

Any comments appreciated, especially helpful ones ! :)

The message from "Tim Mackey" contains these words:

Out of interest...why not? They're designed for it and there's no harm in it.

The only "problem" is that continuously running fuel pumps aren't supposed to keep running with the ignition on but the engine stalled 'cos of the fire hazard in the event of a crash. I s'pose if you wire it up to the starter circuit, that'd kill two birds with one stone...it'd only be one when you're cranking (and it'd fill the float bowl in a couple of seconds unless it's completely dry) and it'd go off when you're not wanting it.

Fuel tee-pieces are common enough...but the pumps don't lift fuel well, only push it, so it'll have to be low down near the tank.

Some fuel pumps only pump when the carb is low, so they are not actually running all the time. Even mechanical pumps only pump to demand even though there's a phyical connection to a cam.

fitting a diesel filter with primer on it , a few pumps and you are away, the valves in the filter head are quite weak and the fuel pump can easily pull the fuel through. Steve the grease
