jstone4646 Posted April 22, 2019 Share Posted April 22, 2019 What brand of mechanical fuel pump would you guys recommend for a 351? I am trying to keep as light on the wallet as possible, without sacrificing any quality/longevity. Thank you in advance! Link to comment Share on other sites More sharing options...
Gary Lewis Posted April 22, 2019 Share Posted April 22, 2019 There's really nothing magic about a particular fuel pump. But, some of them run higher pressure than others, so if you were going to go with an Edelbrock carb later, which doesn't like high pressure, I'd consider the Carter pump. Or, maybe even the Edelbrock one, although it is surely more money. Link to comment Share on other sites More sharing options...

I am not sure how a mechanical pump can be labeled performance other than boosting the pressure, but I think my old motor would be just fine with a $20 pump.

The pump seems pretty straight forward to replace, pull the lines and cap the tank side line. Remove the two bolts, scrape any leftover gasket off if applicable, then just install new gasket/pump. Anything I am missing here or anything in particular to be aware of? Link to comment Share on other sites More sharing options...

Something to be aware of is if the fuel pump eccentric happens to be pushing the pump lever down during installation, the pump can be a bit hard to get in the hole straight. The problem is that the timing cover is aluminum and if the bolts don't go in straight they can cross thread very easily. My truck was like this when I bought it, and the fuel pump bolt hole threads were ruined. So... If the bolts are not threading in easily, you may have to turn the crank a bit to get the eccentric to let pressure off the arm. Just be careful and it will be fine.

Thanks for the inputs guys, I replaced the pump this afternoon without any issue, cant believe how easy of a job that is even from the top on the motor. Still having running issues, made another post for that. Link to comment Share on other sites More sharing options...
