ugh.. ok.. first of all my fuel pump, since i bought the car, made an annoying ticking sound, i think it's on it's way out, whats your opinion? Also today i found one of the typical type clips that are littered on various lines in my car... on my shed floor.. me being the silly prick i am passed it by and went driving.. my car is now sluggish, and just has some serious loss of power.. it has lost it's zing.. i was thinking maybe a vacum line? or something more serious.. excuse my lack of knowledge thanks.

Sounds like you need to trace out your lines and see if theres any kinks in them.If there a clip missing it might have been there to hold up a line or hold it tight.Check all your connections too.It shouldn't take that long.Yeah your pump might be giving you early signs that she's about to die.I say just run it till it dies then replace it.You never know how much life is left in it. https://www.nopistons.com/forums/pub...IR#>/smile.png

my 83 pump makes noise too, i think its normal though, you should be able to hear it with the engine off

Mine makes a humming on my 83 when the ignition is on too.If it doesn't then theres one problem that needs to be fixed.

Fuel pumps are pretty easy to change, they are located under the rear of the car near your fuel tank. (where your fuel-filter is meant to be). We can change that in 5 minutes. With your hose problem, what type of clip was it? A hold the hose in place on the car clip or a hold a hose onto a metal/plastic pipe thingy circlip type of clip? https://www.nopistons.com/forums/pub...IR#>/smile.png

I tried to trace the lines but i was unable to find anything, and drifter, i'll show you. it's just like a little circular type metal clip, that you can find through out my engine bay, is there anything else that can cause significant loss of power? also, the fuel pump doesn't make a humming sound, it makes a constant ticking sound that you can hear even when the engine is running, "tick tick tick tick" in quite a fast fashion. i think i'll carry a spare fuel pump around untill it dies. i'd hate to get stranded :P

yah, maybe it is on the way out



mike

Is it an older diaphragm type pump? Or motor type pump? The older diaph. type

uses an electro-magnet to overcome spring pressure to draw fuel through a

check valve. then the spring pressure pushes the fuel through another check

valve. After the fuel is pushed out, the electrical contacts touch and the magnet is

energized again. (Click, click, click) https://www.nopistons.com/forums/pub...R#>/mellow.png

I'm not sure.. I'll have a look.

Yeah, that circular metal clip is a hose holding onto something type of clip, sounds liek one of your hoses has popped off from somewhere, I'll take a look for you on the weekend. https://www.nopistons.com/forums/pub...IR#>/smile.png

Whoops, forgot to add, you can have my old fuel pump too, I won't be needing it at the moment.

you will be pissed when the time comes TO needing it though https://www.nopistons.com/forums/pub...#>/biggrin.png

Well, I'll need to upgrade my pump and buy an extra one when I get my surge tank set up for the 13BT, so I'm pretty sure I wont be needing it. https://www.nopistons.com/forums/pub...DIR#>/wink.png

the stock GSL-SE tank has an awsome baffling in it, no need for a surge tank. https://www.nopistons.com/forums/pub...DIR#>/cool.png

I agree about the baffling. I pulled out my tank a few weeks ago to rust-proof it. From what I've read it was made like this and with bigger fuel lines to handle the jap 12AT's.

Still, I still wouldn't mind a surge tank set up, its not too pricey. I'm thinking better safe than surgey. https://www.nopistons.com/forums/pub...#>/biggrin.png

Well then just "fuel cell" it and have done with it https://www.nopistons.com/forums/pub...R#>/tongue.png

4 pumps, 3 different feeds to the surge tank, tons of fuel sideways!!! https://www.nopistons.com/forums/pub...IR#>/wacko.png

I thought that you needed the surge tank because the pressure of fuel is to low because its coming from a big tank and that you use the smaller surge tank to have the higher pressure fuel go to the engine, with the big tank and return line topping off the smaller tank. Is that right??

So with the s3(sorry, thats aussie for GSLSE) tank, the tank baffles and fuel lines are big enough to keep the engine surge free??

the reason for the extra tank is kinda like the reason for a "dry sump" oiling system.

several different pickup points from the main source feeding into a small tank. then

using the small tank (never runs out) to feed the motor through yet another pump.



that way, if under hard cornering at least 1 feeder pump is supplying the small tank.

just sitting, running, then all feeders are going and you have an overflow from the top

back to the main tank.

Yeah, thats what I figured, but are you saying that I don't need this kind of set up with the SE tank?

excuse my inability to draw...

I was reading.... I think it is somewhere on this forum about someone who changed

from a GS tank to the -SE tank for the baffeling. they said a stock -SE tank is all you

need. https://www.nopistons.com/forums/pub...R#>/unsure.png



I just can't remember where.... https://www.nopistons.com/forums/pub...IR#>/blink.png

Why wouldn't the return line go from the engine straight to the surge tank? Why go back to the main tank?

in a perfect setup, you will have overflow from the surge to the main. but you're

right, you could go to the surge tank with the return. I was thinking of the possibility

of a restriction of the surge's overflow to the main tank might cause over-pressure

problems that way. (3 pumps + return= lots O fuel!)

I think in DirectFreak's setup, he puts the return to the surge tank to keep it topped off constantly. I might check his thread again. https://www.nopistons.com/forums/pub...IR#>/smile.png
