Fuel pump for 87 K5 TBI

[brans87]

Looking for a upgrade fuel pump for my 87 K5. I see http://tbichips.com/?product=ac-delco-high-pressure-155lph-fuel-pump. Has this one but little pricey are the another routes. Figured might as well replace one in my K5 while gas tank was out since I do not know if or when it was ever done.

96 c3500 350 vortec is a direct fit to stock 87091 sender and plug end.

gets you mid 60psi capable psi . its what lots of guys use for vortec / ls swaps.

Looks like the EP381 correct? So just get the pump and sock? Should be a direct fit to my 87 K5 your saying?

got 1 on my 2wheel burn project .

now the stock tbi regulator will still only give you stock pressure .

so all you will be doing is a bigger pump for later upgrade basicly.

EP381 is the number I kept seeing when people were talking about a high pressure TBI pump. You'll have to let us know if you have any issues. I suspect you will not.

Also, pay attention to the box. That looks like a newer one, if you don't mind, let me/us know where it was made.

I just installed a Delphi version of the delco ep241 in mine b/c the precision stock replacement pump crapped out after 4 months. 50psi capable. Runs great, only issue I had is u need 5/16 submersible fuel hose to go from the pump outlet to the 3/8 sending unit hard line inlet. $30/ft and all I needed was 2" lol

I think the 241 is the TPI pump, that's the reason to go with the 381. The TPI pumps have a different diameter fuel hose for some reason, the 381 is the right diameter for the TBI apps.

Yep it's the TPI pump, wish I'd known that about the vortec pump, oh well
