Electric fuel pump

[Dan]

I would like your guys opinions on electric fuel pumps in early Z's. I have a Stewart Warner pump and a Holly fuel pressure regulator that i'm thinking of putting in. I'm thinking that it would provide easyer starts and perhaps slightly better performance, any thoughts?.

Well, I only have 73 & 74, they both came with both electric and mechanical fuel pumps, so i am not sure. Are you using SU carbs? I would doubt it would make a difference, unless you've run into fuel starvation symptoms, or are racing or such.

I think the stock mechanical pump provides enough fuel to keep the bowls fairly full, but as i say, i only have experience with the later cars. At any rate, it certainly can't hurt, as long as the pressure is kept regulated. HTH, JA

The 240 came from the factory with the mech.pump.In an attempt to resolve vapor lock problems,the dealers (at the factory request)installed electric pumps in series with the mech.As far as a performance enhancement,I doubt you'd notice.Help it start better? No.I would suggest getting a fresh base to start from.I would replace all the basics.Spark plugs and wires,dist cap,points,rotor,condensor,air filter etc.The fuel filter needs replacing also.Some cars had a rear filter near the fuel tank as well as the front one.Make sure they all get replaced.By getting this fresh start you know what you have.Follow your haynes manual and pull out the distributor.Check the position of the pointer on the Advance/retard mark before removal.The Z is so sweet from american cars. The dist. will only go back in the correct way!It's foolproof!Check/clean the connectors in the dist.They oxidize with age=bad connection.I recommend the NGK factory spark plugs.I think their BPR 11es.Check that number.Change wires/sparks one at a time so you don't get mixed up.When all is done,the only remaining items are getting the valves adjusted and head bolts torque checked and timing check.Those item would be for your local shop.Then its carb cleaning time! Have fun!! Daniel
