Secondary fuel pump dead?

[2poor4aZR1]

Just browsing the web,

https://www.lingenfelter.com/product/L710030390.html

Asking out of genuine curiosity, any reason you can't swap the OEM fuel pumps for a set of Walbro 255s? I mean, it would mean modifying the factory mounting brackets.

Are you sure you don?t have a crack in that plastic Y? They are old and brittle; Carter200 makes a replacement if so.

The other option is the stainless steel single pump unit that Dan on here makes.

At first I bought the Y connector, but I decided to just go stainless single pump and never looked back.

I have Carter's Y replacement. The new single pump option looks good, but it seems to be rated up to 550 hp. That would be right on the edge for my 415 which is approaching 600hp.

I bought a set of GM OEM pumps following an advice here in the forum. They're made for big 455ci (?) Suburbans. Never installed them (mine are looking and working very well) but they look proper.
Also they were NOT made in China, something I really appreciate.

I can look for the exact type but it's also somewhere here in the forum.

Got it; I did not notice your signature and I understand. I would love to have your problem. Lol. I thought Lingenfelter sold good pumps?

[Subfixer]

New pump kit from Lingenfelter arrived today. 2 pumps, made in USA, adaptor pigtails, new bolts, o-rings, gasket, socks. Only thing missing are the 2 tie wraps that hold the pumps in the holders.

Lingenfelter part #: L710040390 (high flow)
For Standard flow: L710030390

Hey Subfixer, glad to see you got pumps that will work for you.

I wanted to say that in a previous conversation Haibeck told me that the 67 GPH pumps that come with the single pump conversion kit are capable of supplying up to a 650hp engine.

I think you went the correct route here, but its worth noting at least should you ever need it in the future.

Subfixer,

Replaced my '92 original fuel pumps with 2 - Walbro 5CA400 pumps and they work great.

Subfixer, did you go with the high flow or standard? My primary pump stranded me yesterday and this looks like a nice "may as well do both" solution. I considered going to a single pump, but I kind of liked being able to run on only the secondary to limp home if the primary dies again.

The car is currently around 540 crank HP, so I'm thinking perhaps the high flow option provides a little assurance I don't need to go to something even bigger later if I do any more modifications.

I got the high flow pumps as I'm pushing around 560 crank hp.
