Factory Gas EFI in tank pump for lift pump?

[riotwarrior]

Ok so looking at another swap maybe if I get this donor truck.

Don't want to use a stock lift pump..just a nice electric, that being said, I was thinking of a regulated supply just prior to filter head and using the factory in tank EFI fuel pump...anyone got any thoughts on that?

 

[Wyreth]

Would that survive diesel?

and as far as nice electric fuel pumps go, what's wrong with a Facet Dura-Lift?

Or are you wanting to try something new?

 

[riotwarrior]

nope,.just thinking that the stock.gas.efi pump in the.bronco should.work ok...just curios is.all...

 

[Wyreth]

ah, well provided the diesel doesn't eat it. It should work ok, hell it might last longer than normal as diesel would lube the impeller better.

I say try it and report. =P

One downside is when the pump dies it is a pain to replace. With a pump like a Facet mounted under the hood it can easily be replaced on the side of the road with just a couple hand tools.

I am with the rest of the group...even if the factory pump would last with diesel it would be a pita to change on the side of the road.

You would probably have to regulate the pressure down as most EFI systems run around 40#s of fuel pressure (even these are regulated down) which is way to much for your IP.

If your Bronco was like mine, you have an in-tank lift pump, and a frame mounted pump. A bypass type presure regulator would work fine if it can deal with the 50 PSI those things put out.

Hey Mel,

speaking of bypass regulation, I've seen a lot of different models presented here.

This one by Holley seems to fit our bill perfectly : http://www.holley.com/HolleyNews/article.asp?ID=25

I'm assuming.... ready to become the 1st three letters of the latter... the return portion can be plumbed into IDI return line, say at the back by the last olive- replaced by a four way port?

Do you see a dilemma with it? Possibly too much back pressure on the factory return lines?

OK the stock gas pump is probably a Walbro or Bosch, why not see if there is diesel walbro, Bosch pump that is the same dimensions as the gas pump? See if the GM e pump is close. Or one of the 4 cyl. E pumps out there may fit. There has to be some thing that will "bolt" to the stock housing.

Mel, mine is just a simple in tank setup....no frame mounted pump...I'm gonna put a tester on the fuel rail...see what that pump puts out while I still have a gasser in there.

On a side note 140-150 all across for comp for my 5.8...plugs looked great just opened them up a tad....from 43-48/49 ish changed oil and now gonna set it for sale after I do a cold start video and a warm running video.

Be careful changing your oil and then trying to sell a motor... i yanked the 302 out of my BKO and still havent sold it nearly 3 months later. No one trusts fresh oil, its like they think my motor was trash, and i changed the oil to make it look like a good motor... And heck im only asking 200 for it, with computer and wiring... Maybe thats just the kind of cheap-o people that live in PA, keep gettin 50-75 dollar offers due to the *oil change* and possible bad motor, with running/driving/starting videos....

Never mind the fact that im religious with sea-foaming gas motors and after 3k miles my oil is only slightly shaded.

Just a word of warning, as said, clean oil = suspicious people around my neck of the woods
