mcs Posted May 1, 2006 Share Posted May 1, 2006 fuel pump pressure issue on EA82, carb, auto choke, manual 4x4 (1987) I apologise for such a lame question but I replaced my fuel pump a while ago ( previous one dripped fuel ) but I have just noticed that when I'm on tick over my manifold vacume isn't constant and my exhaust smells a little rich. I believe that my needle valve is being over powered by the new fuel pump but I can't find a reference to say what the PSI should be. I bought a generic pump designed for cab engines which didn't specify PSI on it but I'm going to connect a gauge to it tonight and find out. If this is the case does anyone know of a place I can get a simple fuel restrictor, no bells or whistles, or is there anything I'm missing. I don't want to buy another pump unless I have too. Incase anyone is thinking, I had replaced the fuel filter a little while ago which is probably what caused the original fuel pump to malfunction in the first place.

GeneralDisorder Posted May 1, 2006 Share Posted May 1, 2006 Should be around 2 - 3 PSI. You can get a pressure reducer from any good parts store usually. The performance places that sell lots of holley and edelbrock stuff usually have them. GD Quote Link to comment Share on other sites More sharing options...
mcs Posted May 1, 2006 Author Share Posted May 1, 2006 Thanks matey, thats obviously my problem then as new pump says 7 psi on the side. Strangely enough new 1-3 psi pump is cheaper than new damper. Ohh well, serves me right for not double checking before fitting. At least it ends with a cheap solution. Thanks again:banana: Quote Link to comment Share on other sites More sharing options...
