351w Fuel Injection Conversion

[kman67]

I'll be curious if you can get the Explorer fuel rail to work with the distributor on the 351W. I had an interference fit on mine (5.0) and had to keep running the Mustang rails. It seems to be a common problem based on a number of posts on the interwebs.

I just went out and test fit my motorcraft dizzy on my Edelbrock 3880 (now replaced by 3884) intake with the Explorer rails. There seems to be plenty of room, maybe because the 5.8 is wider? In my picks I used a heater tube from a 86-93 mustang as the explorer tube put the coolant temp sensor hitting the intake. I did bend the heater tube to water pump down a bit as it’s meant for the 5.0. I’m also using the Explorer front dress with the Saginaw bracket from wild horses like you, without the AC pump.

Thanks for the detailed pics! Definitely looks like it's a 5.0 vs. 5.8 thing. You've got miles of room.

I like that rails fuel pressure port location. The van and F150 5.8L has the port on the D side and it's VERY VERY hard to get to (if at all) when using the Explorer upper.

I might have to look at upgrading

This what my '96 FSB looks like, memory says that the supply and return connections are sort of behind the DS cylinder head, but I'll need to look to confirm that:

Other than being "way over there" I don't recall access being all that difficult. The 1996's are unicorns in other systems, could this be yet another one?

where did you find the roller block?

Kyle, do you have a pic of the firewall end of your engine? Curious about your valve covers, where is the PCV port and oil filler tube? My fuel rail looks like that but I had to lengthen the hoses to get it to span the lower intake.

Thanks everyone for the great information!

Any thoughts on the Explorer return less fuel rails?

I also had to use longer fuel injection hose to span the left and right side as the 5.8 is wider. My PCV is at the driver rear valve cover and the fill is at the passenger side valve cover. I plugged the stock PCV

hole at the rear of the intake.

I have been going back and forth about what rails to use. I am going to use whatever fits the best based on the feedback here and what info I can find online.

I’ll update my first post accordingly

I'm just using stock bronco/truck fuel rails. I can get pictures later if you need them.

Pictures would be great!

Im pretty sure this is the bc broncos fuel line kit, but it could be wild horses

Thanks, looks great! Your fuel rail setup is the same as mine. I'm still using the PCV port at the base of my lower (Trick Flow) intake but comments here have gotten me to thinking about abandoning it and going with the plumbing like you and @Timmy390 have. My engine burns a lot of oil but it doesn't seem to be affecting the plugs, and the intake is getting nasty already. Guessing my engine is vacuuming up oil through the PCV also. What oil filler are you using with those valve covers?

I’m using just a generic cap(Mr Gasket) with a port that goes to the throttle body to keep the system closed.

Good info here

I have a 351w roller engine from a 96 van

One owner about 100k on the van

FYI, that heater hose will not survive long term with the oils. It will either get really soft and gooey or hard as a rock. Should bet a couple years out of it, but the rubber in them is for coolant, not hydrocarbons. Not a fix today issue, but just be aware of it long term.

I noticed that when I took the pic. It's been in place for about 10 years and is getting hard. I would like to find a filler cap that has a 3/8" outlet that matches the throttle body inlet. And then get a 3/8" hose that is oil compliant.

Does that all fit under a stock hood with no body lift?

Probably need a 1" body lift.

Thank you. The motor I got came with the Holley Terminator X on a tall ram, but that setup is about 6" too tall. I wanted the EFI, but the easy way forward is a low rise with a carb...
