to all you fuel injection wizards, in need of expert feedback Options

[orange914]

to start let me explain the 914 fuel system as i understand it. please correct me if and where i'm wrong:
1) fuel comes from tank to pump, bottom nipple on pump
2) high pressure out of pump to regulator, middle nipple on pump
3) reduced pressure fuel from regulator loops to and past injectors then back to pump, top nipple on pump




if this is the true operation
i should be able to:
1) mount 914 pump near tank (1969 ranchero v-8). run high quality lined goodyear hose (better than oem vw hose used on 914 system) to 914 regulator (30 psi) say 12 inches from pump output.
2)after 914 regulator outlet (30 psi) install a "tee" in line to return unused fuel pressure. thus "mimicing" the fuel return loop of a 914
3)run 30 p.s.i. fuel from 914 regulator/return tee forward through (stock 3/8" steel line) to 2nd regulator at carb. this dial type regulator would hold pressure to 4 psi at carb

I think its generally considered to not be a good idea to "pressure down" the stock FI pump to work with carbs. Unless you like fires....

Buy the right fuel pump for the job...

I agree, quit being a cheap @$$ and do it right (IMG:style_emoticons/default/smile.gif)

the 914 pump will have too much pressure and I wouldn't trust the 914 regulator to be able to reliably reduce the pressure needed....if the regulator failed, you could have a major gas fire since now you'd have gallons of gas flowing out of the carb in just minutes...
