I'm going to fit a solid state fuel pump from ebay to my 86 model because David Silver wants stupid money for a pump. I'm not sure what pressure the pump I have will push but I think a max of 6lbs. Because I'm unsure of what pressure the needle and seats can handle I am going to fit an adjustable pressure regulator in the line after the pump and allow the excess pressure to feed back into the tank feed to the pump. Any thoughts? Anybody know what pressure the OEM pump pushed? Thanks Norm
3 psi is normal. The exact same Mitsubishi pump was used on a vast multiple of common Japanese bikes for years during the pre-FI era, so i'd look in a breaker's yard first. Have you tested the pump with an ohmmeter across the 2 wires ?? Pump relays fail more often than pumps.
Thanks Squirrelman, we have bugger all breakers in Aus, those pics are something we couldn't imagine,I don't know where all the old bikes end up out here. Pump is shot, was full of rusty water for some years, power to the contacts but pump has no hope of running Thanks for the heads up on the 3psi, I was going to start with 1psi but I didn't want to end up running lean. I'm not sure what gravity fed tanks produce but it wouldn't be a lot. Thanks again
It's nuthin, mate. I'd like to be a foot taller; but if not possible, i'd wish to be Australian, cocky bastards they are !
Ok another little thing, after cleaning the tank of the rust I discovered that there is about 6 litres of fuel left in the tank after the reserve stops running. Is this normal and has anybody done anything so that this fuel can be used.Not a lot of point in carrying around that much fuel you can't get out of the tank. In my case this was obviously full of water for quite some time, untill the water got high enough to get sucked into the carbs and then it was parked up. I was thinking of putting a fitting into the fuel sender plate with a tap so if needed this fuel could be used. At least every so often you could open it and see if any water had gotten into the tank. Any thoughts? Cheers Norm
