Electric fuel pump

[cubbear]

I changed from fuel injection to carb. in 20,000 mi I have went thru 3 holly red pumps. anyone use stock in tank electric fuel pump with regulator and return line?

Lots of us use in-tank fuel pumps. Probably as much or more than external pumps. I don't know how often they're actually stock though. Hard to provide much of a recommendation without more information. But what I would suggest is to contact Mark at http://www.breezeautomotive.com/ (forum vendor) and describe your setup. He could recommend and provide what would work for you.

I used the stock in tank pump, a Mr. Gasket regulator and 3/8 inch feed and return lines. Works good.

Breeze, as mentioned above, has the pump hangers for the in tank pump with the return line setup.

After reading how quick guys go through electric pumps, I decided to change the front timing cover and go with a mechanical pump. No return line needed either.

I also went through several in-line electric fuel pumps with my carbed engine. A few years ago I converted to an in-tank pump but also added a Trick Flow/Aeromotive regulator to drop the pressure to around 6-7 psi. So far I'm much happier with the in-tank, return-style system. Much quieter and also much more reliable.

Do Ford factory EFI engines have an eccentric to drive a mechanical fuel pump? (I wouldn't think so.) Because if they don't then adding a mechanical fuel pump isn't quite so easy...

Info i saved from a thread about a month ago;
"In the early 80s ford used an intank fuel pump rated at 4 to 5 psi out. I am running this on a 351w carb with no problems and no return line. The number I used was an APE A1068. It fits the mustang intank bracket."

No they do not. Which is why you need to change the front cover and timing set. So yes, it can be a headache. However once you are in there, it is pretty simple.

Just an FYI and this may or may not be a contributor to pump failure.
An electric fuel pump needs lots of current. I've heard of many failed pumps often due to the wiring connections and insufficient wire gauge. My understanding is that it's usually best to wire the pump direct to the battery with proper wire and a relay as the switching system.
My personal experience is with carbs and mechanical pumps.

You mentioned going in-tank with a return line. Have you been using a return line with the Holley pump(s)?

I did not run a return line but have a regulator pump pressure preset 7psi

For an extended operation environment like street driving, it is really important to us a return style regulator with a properly plumbed return line to insure long pump life. You can only get away with using a dead head type regulator or none at all on a Holley pump in short duration situations like drag racing. Your 3 pumps in 20,000 miles is proof of this. If it's plumbed correctly your Holley will last as long as anything else out there. Also make sure the pump is below the tank to keep it fed with fuel. Running it dry trying to suck fuel up from the tank will shorten it's life too.

OK, I have a Holly external fuel pump and called Holly to ask about filters. They recommend a 100 mic mesh before the pump and a 40-60 mic mesh before the carb. They say this set up prolongs the life of the pump considerably. I've been running my holley fuel pump for about 6 years with no problem. It is noisy but the noise disappears when the engine starts.
