Forgot they were aluminium. Applies to only copper. Mr hunter is correct . Sorry.
Now I was wondering if copper seals could be substituted if you had them around in your toolbox. Is it a torque sealing issue with each type material? Or just an economy issue? Aluminmium is far cheaper to produce seals from. |

The aluminum seal rings are cheap, MB engineering/durability selected them after many millions of dollars in testing. FYI data to consider... Long term storage of diesel http://amsca.com/files/Download/Fuel_news_long_term_storage_diesel.pdf http://www.lcbamarketing.com/long_term_fuel_storage.htm Waste vegetable oil reacts with copper to form a "greenish slime". Material compatibility Free fatty acids in WVO can have a serious detrimental effect on metals. Copper and its alloys, such as brass, are affected. Zinc and zinc-plating (galvanization) are stripped by Free fatty acids in WVO. Tin, lead, iron, and steel are also affected. Stainless steel and aluminum are generally unaffected. |

YEAHH!! We plugged the return fuel line and it was VERY VERY hard to press the pump button this time!!!!!! So then we cranked the engine and ALL 5 INJECTORS SQUIRTED FUEL this time!!!!!
I am ordering the parts right now listed with the link above! Thank you very very much for a those of you who stuck around and kept throwing ideas to us! We will keep you up to date when we get the parts! |

also my dad ended up unscrewing all the fuel lines including the hand pump area as he was planning on pulling the injector pump out.. Where can i get seals for the hand pump?

That sealing washer is an odd size. I could go look in a box with a spare primer pump to see what material it is made of. I try to always have a spare around. Where it is at the moment is the question.
I believe the maximum possible fuel pressure it sees is only 30 or so pounds and that is only while testing with the return line clamped off and the other components in the system in good condition. If copper heat it up pretty good and let it cool. Or take a chance on reusing it. If it will not seal you will know quick enough. Now if your old relief valve was just gunked up try it after cleaning with laquer thinner. Buying parts is costly and painful if not required. Certainly purchase one if needed. Just make sure it is needed first. Your choice of course. |

I ordered the following parts.
(9) of the 007603012111 (3) of the 007603014405 (1) of the 0000747284 ========== So basically my spring valve currently doesn't hold any pressure. Its squeaking right now when you prime (since i cleaned it)... But you can prime 200 times and the button doesn't get hard. So i can't fire this thing up until i get the new parts. Now we play the waiting game |

A lot of the time the presence of any air is modifying the feel of the primer pump until it is expelled. I do not think you had air to contend with or very little. So your push pressure just might be right with no air. When you clamp off the return the output from the injection pump base is effectivly closed. You cannot pump fluid in a closed system. Fuel like all fluids does not compress. Kind of a general statement there but okay for our needs. The primer pump cannot basically be moved if everything is right. You call it very hard and it would be in that senario. I would try starting the car now. It may suprise you. I think it will run. Or until your parts arrive why not read the relief valve spring thread started by Cervan. With a little luck you will get through it before your parts arrive. Anyways I think and hope your problem is now resolved. I would post how this engine runs sometime. Your experience to me indicates it may be a candidate for further improvement with no or very little money required to achive it. A lot of these cars have experienced neglectful maintence if any over the years. Last edited by barry123400; 06-17-2010 at 06:33 PM. |
