#EDELBROCK CARB FOR A 69 EL CAMINO 350 INSTALL#

That all changed within the last few years.Ī couple of years ago I had so trouble much starting my engine I added an electric pump just to prime the system, turned if off and let the mechanical pump take over. My experience was electric pumps was terrible, left stranded several times, so I had little use for them. I loved mechanical pumps because they lasted for decades and I never had one fail. That said, I'm not saying heat soak may not be the issue for the OP.įor what it’s worth, I’ve run Carter AFB’s or Edelbrock AFB’s with a mechanical pump most of my adult life. Even if it's just making 6-8PSI like many are supposed to, that's really too much. At the least I'd put a gauge on it and check it, and add a regulator if the fuel pump is making over 5.5PSI. Most recommend 5.5PSI or less for the Carter style carbs. It seems to be common now, which is probably why so many insist that these trucks get really poor fuel economy and that carburetors don't work. No, it has nothing to do with pumps 'getting old' it's brand new pumps that cause problems. you just need to keep the oil/gas/water away from it, it's compressed wood. the wood 4hole square bore spacer you got is a good one and will insulated better than plastic at that thickness. I believe the gas pressure should be right about 6 psi max. a spacer will fix that, fixed mine anyway. but edelbrocks are known to suffer from heat soak on hot motors.

Yes, pumps do get old and it wouldn't hurt to install a new one. If you search 'sbc mechanical fuel pump pressure' you get a lot of results from pumps putting out too much pressure. Never hurts to test the pressure and see what it is. I also think (IIRC) that the later SBC pumps (some of them, anyway) are spec'd at 6-8PSI to begin with, which everyone seems to agree is too much for the Carter carbs to deal with. I've heard of other guys having similar problems with the new pumps like that I personally like the ones that screw together (I ran a real 50's AC-Delco pump I rebuilt on my 283).

The big-pressure pump described was a generic 'Airtex' brand stamped-together mechanical pump. Thanks for giving me the exact part number makes it idiot proof. Are the mechanical fuel pumps prone to putting out too much fuel pressure? I also have a wix fuel filter in line under the cab. I have a regular mechanical fuel pump, and I still have the tank in the stock location behind the seat. Thanks for all the advice guys I will run up to the parts store and get me one of those spacers.
