EFI fuel pressure????
« on: October 03, 2005, 08:57:37 PM »
 I asked a couple of people what the fuel pressure was in the  1.6's and got answers all over the map ???
 I called the dealership, they said 35-40 psi but I question their answer cus after buying parts from them I realized the new dealer with all new staff didn't know much about zukis or cars for that matter >:(

 Anyways I bought a holley inline pump says it's set for 45 psi / stalls at 90

good, bad, I don't know
some educated advice would really be helpful ??? ???

I would think that would work, just mount it as close to the tank as possible and if you have a plastic fuel filter make sure it is on the sucktion side of the pump.

i got a 125psi fuel pump in my suzi but it is a bit over the top
around 45psi sounds about right the fuel regulator will be set a bit lower

IIRC 35 to 40 is quoted in the FSM as the regulated fuel pressure for the regulator. A 45psi pump should be OK, the surplus fuel will just go back to the tank.

 Thanks for the info, I'm renting the engine hoist Friday so with any luck the sami will be runn'n by Sunday, all HI TECH (EFI)

 I know I'm a little red neck but I like stuff I can fix, can't rebuild an ECM on your tailgate ;D

Engine hoist for a zuk engine?   drink more beer and let the air out of the front tires you can lift it out by hand!

 I put the new engine on the stand by hand, it's not that heavy but if you look at Zukipilot's poll on how tall the average zuki owner is I fall in the "stubby" catagory ;D ;D

 The rental is only $25 a day so it should only cost me $12.50 right ;D

 Will post pics when it's running, I painted almost everything & polished the TBI intake tube

PS maybe the little saying under my info will finally come true 8) 8) 8)

I run a 1989 1.6L 8-valve in my samurai.  I used a NAPA fule pump part# TFP2P74028 (~$70).  This is same as AutoZone part# E2000 (~$99.99).  They say right on them: 90psi.  This is ok (even without a regulator) if you run your fuel return line (very important).  Good luck with everything!
ps - they're a bit noisy.  mount it in rubber and try not to mount it on the body, go for the frame.
