Where the fuel line comes into the compartment at the side of the shock tower I plan on attaching a few inches of rubber fuel line to the electric pump, then add a few inches of rubber fuel line to the regulator. The from the regulator can I go rubber hose line to the carb or should I go braided line or stainless steel line. Does it matter from a safety standpoint if I used rubber from the regulator to the carb. Somewhere in there I want to install a fuel pressure gauge. I want it to look good but dont want to spend hundreds on plumbing. Your thoughts
Electric fuel pumps 'push', rather than 'pull'... They should be mounted as close to the fuel tank as possible. The regulator should be as close to the carb as possible. My .02 Dave
Well, you are moving flammable liquid.Dont want to get too cheap.Use at the very least good teflon lined neoprene hose for fuel injection applications.And good band clamps/not the worm gear type.(they like to loosen up)Your fuel pump should be at the lowest point in your system and as close to the tank as possible,not under the hood.Make sure you have it on a dedicated circuit as well(No sharing w/other electrical components)Ignition switch is a good place to put it if you dont give it its own on off switch.All hose connections and splices should be to a barbed fitting or dedicated fuel line type fitting.No cut to fit plain steel tubing.Safety is important when dealing with fuel delivery.Dont make it a consideration,make it the rule.Good luck,hope this helps you.I am sure I have left out the little details but guys will chime in with all the things I failed to mention.Have fun!!!Pete.
I have never had issue with regular rubber fuel line... I don't know anything about "teflon lined neoprene hose". I suppose one could go all out with something like that, but I wouldn't say not to use rubber hose or worm gear clamps. They have served MANY folks well for decades. If you take the car to the track, they only allow 12" total rubber hose in the fuel system. So if you have 4" off the fuel tank, you can only have 8" combined elsewhere... Just as an example. The tracks don't outlaw worm gear clamps to my knowledge either. Anyway, the reason I came back was to recommend an oil pressure switch for the fuel pump. This keeps you from having to run the pump to a manual switch, or from hooking the pump into the ignition power, causing it to run all the time. The car will start without the pump running, using the fuel in the bowls. Then the oil pressure goes to operating level, turning on the pump. If the oil pressure drops below a set level, the fuel pump turns off. This could save your engine upon oil pressure loss, this would also keep you from loading the bowls on an engine stall. Nice safety and convience feature.
I agree with you Ratio,I was just erring on the side of safety is all.I would at least use rubber hose for fuel injection.(more burst strength)The teflon stuff is pricey.Worm gear clamps though.Look at all the leaky tranny lines on cars that use em and then tell me they are good(Im biased/I dont care for em)from a safety stand point.They have their uses dont get me wrong.I just dont use em for fuel/trans lines.You are right on with the oil pressure switch.
Although I agree with you Mavman, all rubber lines and worm clamps DO do the job. This is what the fuel system on my 89 Ranger consists of (low pressure carb) and has been doing the job for 6 years now, without a leak. High pressure? Then I'd have gone to better stuff. I was lazy when I put together this system.
As for passing tech at the track Dave, I've got more than a foot of rubber line in my Comet, and so far the "A" hole tech guy at the track I've been to here hasn't told me anything about it. He might next time (he seems to focus on 1 or 2 things in his inspections each trip) but hasn't yet.
Most of the leaks on the trans lines are from people using FUEL hose rather than the proper hose (power steering return hose), I have power steering return hose going to my cooler and it has never leaked.(I use worm clamps) Although i recommend using the shortest amount of rubber hose in the fuel system that is possible.
I know they do baddad.I am just an overkill anal retentive sort about some things.(guess my aviation background with the navy plays a part in that)Old habits sort of thing i guess.
