Fear not, the effect will be negligible. A 90 degree fitting is the
equivalent of less than 2 ft of straight tubing, according to my old Chem E.
textbook which deals with pipe, but since pipe has a rougher surface than
tubing the friction loss will be even less for tubing.

Subject: Europa-List: Fuel pressure question
Classic 914 mono
I was wondering if there is valid discussion surrounding the effects of
substituting a 90deg fuel fitting for a straight-through one at the
firewall. We are talking 3/8inch aluminum and -6 fittings here. I have
installed the latter in order to present a serene curve to the fuel
downstream of the requisite pumps, but wonder whether replacing it with a
90deg model for ease of routing would affect the efficiency of the flow or
have any effect in producing evaporation due resident heat etc - or in fact
anything at all?
Any comment gratefully received.
Cheers, Ferg
