    INJECTORS

    The seat for the pressure relief valve was good.The pressure barely comes up in the red. The only way he can get the pressure up is to use air compressor. We checked the injectors and all we got was drips.Don't know if it's the transfer pump or the injection pump or something else. How much does...

    Still have low fuel pressure. Diesel engine will not run. Just put in new pressure relief valve and spring. How much pressure should you have at the injectors if the pumps are working right? Thanks!

    CAT D-4 PARTS

    I kind of wondered about that number because my husband has an old CAT 7U parts book and the spring number was the same as the one you gave me but the plunger was 8B8917. About the exising valve, I guess they had it out and cleaned it all up but they were not sure if the spring had enough...

    Very Low fuel pressure

    Well, we are really not sure it is the pump. I guess he is going to try to find the pressure relief valve and spring and try that first. Thanks

    Very Low fuel pressure

    I found someone that has a CAT transfer pump on Ebay. The part number is a 231-3947 .The guy says the pump fits a variety of Cat engines the most popular being the 3406,but it is just outdated by Cat standards. Would this fit a 1953 6U7422 D-4 Dozer? Thanks for your help!

    Very Low fuel pressure

    Still have Low fuel pressure on our 6U D-4 Dozer.Has new filters.Has flow to the pump, and already had it running once, so we assume maybe it could be the transfer pump relief valve & spring.Does anyone know the price for one of these and where to purchase this assembly? Thanks!
