i have been having fuel pump issues. was thinking about going electric. is it a good idea o rshould i just get a good mechanical unit.

 

I would continue to use the mechanical pump and not have to put up with the whine of an electric pump. My 2 cents.

 

A good mechanical pump is the way to go. Check into the carter 120gph pumps.

 

I have an electric because of the march pulley system I have. If I had to do over again would not have went that way. Mechanical is fine for most apps and one last point of failure

 

I have a March pully setup with a mechanical pump.

 

So After building my new engine, I need to use an electric pump. I bought a cheap $50 mr gasket pump but it gets too hot here and it is locking up and it quits pumping when im in traffic.

is the holley blue pump a good way to go or should i step it up and by a higher end pump.

I think you've picked the two extremes for available fuel pumps: cheap bull**** and high end overkill.

Airtex and Federal Mogul both make generic inline 12V pumps that put out 5-9psi (keep in mind, you'll need a good regulator). I won't be at work for another week so I don't have a number handy, but a quick flip through the fuel pump manufacturer's book at your local parts store should get you something that's higher quality than the crappy Mr Gasket pump, but not as expensive as the Holley Blue pump.

 

Do NOT ever use cheap pumps and regulators. Ever.

Just get a Walbro 255lph, tried and true, feeds plenty of power, lasts a long time, not too expensive.

Also if you mount it external, make sure the pump is level with or below the bottom of the tank.

 

Forgot to add: figure out something for a safety cutoff. Either pirate an inertia switch from a junkyard Ford, or use an oil pressure cutoff. Electric fuel pumps are safety hazards in accidents and need to have a safety cutoff.

 

If I use a oil pressure switch, should I just use a tee where my current oil sending unit is?

Also, I'm in AZ and it's dam hot. My car when I'm in traffic gets really hot. I already have 3 electric fans, one pushing and two pulling. With a really big radiator. I do have ceramic coated headers but will wrapping them help reduce the heat in the engine compartment
