I think the in tank pump is going out again on my 88 bronco so I am thinking about going to a carb and duraspark ignition,its nothing with the system but its the quality of the replacement fuel pumps that I am having a issue with. I had to replace the in tank pump when I got it and it went out again in less then a year and this one has only been in about 6 months,I will try to get the parts to convert to a single pump system this summer but if I cant find a complete system I am also thinking about a upgrade to a 351 so I will be on the hunt for a 85 to 87 351 HO and get rid of that stupid serpentine belt system while I am at it.

 

Never researched it, but is it possible to rig up an access panel so you can change the pump without having to drop the tank? If so, that would be MUCH better than nixing the efi.

 

cut a hole in the bed. weld a hindge on it and wala, access panel in 15 minutes...

 

It's a Bronco, it has no bed. I always cut holes in my floor because I'm too lazy to do it the right way and I want the chance of killing my passengers with carbon monoxide.

You just need the pump assembly, and two short pieces of fuel line to eliminate the SFR and frame pump.

 

I have located a low mile 85 4 bbl 351 so I am getting tempted to go that way,I think it will be much easier just to use a carb motor then to convert a EFI motor.

 

Lots of vehicles have access panels like that. Hell, it's a bronco...chances are there's already a rust hole there. Cut a panel and use screws and butyl. No exhaust will get in.

 

How are you going to screw down a piece of metal that is smaller than the hole? It doesn't grow when you cut it out. Some cars may have an access panel, his does not.

EFI or carbed, the block is the same.

 

If I can find the parts to convert to the single pump system I will keep the EFI.
