can i use a TPI350 fuel pump on a throttle body car?

 

Sure can, bolts right in. I would just go ahead and get a walbro 190 and be done with it. This pump will feed anything that TBI will support, I would tell you to get a 255, but there have been reports of the pump having too much volume for the stock return ports in the TB. The 190 is a proven performer. If you can get a TPI pump for dirt cheap then go with that, it'll do the job as well, but the walbro pump will give you some extra head room in case you ever get serious with it.

 

but it wont damage the injectors at all?


could i just use a oem replacement L98 pump?

 

You sure could.

 

you have done it?

 

I have. The TPI pump will work just fine.

 

awesome, thanks

 

I recently bought a walbro 255 but haven't installed it yet.what can I do to my ports to be able to use it? Sorry don't mean to hijack the thread.

 

robertfrank, what HP numbers are you running

 

I couldn't tell you there's no dyno in town.I wish I knew.

 

I have run a Walbro 255 @ 22-25psi with no problems with the return ports on an adjustable fuel pressure regulator(same ports as stock just adjustable)

But if you don't need the Fuel Pressure why would you need a 255???
So I don't think most people have that problem.

 

Basically the guys that had the problems were trying to get their pressure down to a stock 12 psi with 45 lb/hr injectors. If your running higher than stock FP and bigger injectors you shouldn't have any problems. A 255 isn't needed with TBI, it will support over 500 HP but at only 105$ why not.

 

I run a wlabro 255 unit in my car and my bud runs one in his LO3 vortec headed, LT1 camed car. I received mine for $97 shipped to my door. I wanted it because I would like to go Gen II/III in the near future.

 

oh ok I won't be using stock pressure or injectors.(350 injectors and EBL)
so I guess i'll be ok then.

 

If you're running a stock TBI unit with a relatively mild cam , a 190 lph pump will work just fine .
