Single fuel pump recommendations B230F

The car is an 87 245 that I've owned for 2 years. About a year ago, while diagnosing a fuel problem (hard starts, stumbles) I found the inline pressure pump dead. I thought it pretty strange that the car would run at all so I removed the sender and saw that the VDO pump had been replaced with a larger, newer, generic in-tank high pressure pump.

What I ended up doing was bypassing the inline pump while keeping the check valve and filter in the stock location and giving the in tank pump it's own relay since I had also found a melty fuse and the stock relay ran hot to the touch. The generic pump I was going to let run until it died. Well it died.

What is the consensus on reliable single pumps- the Walbro 255lph? This isn't a performance application, the most planned for the future is a 531 head with a zippy cam and some exhaust.

The cheap part of me is tempted to go to U-pull-it and just a grab a recent Toyota Denso in tank pump or something. What do you guys use?
 
I can second a DW (301) pump. I use it in my Evo and it's miles better than the whinebro255s in that I can hear my car and not my fuel pump lol.
 
I have a DW300 in my GLH and a DW200 in my 850 Turbo.

3 year no fault warranty is great.
Dead quiet compare to Walbro.
 
Interesting everyone is in agreement, I'll check those out. Thanks. Embarrassed to admit it's a brand I have never heard of.
 
Get a cheap stock replacement. Unless you make 350 whp with your 531 head I would not worry about it.
 
Hi , I used a high pressure pump from a BMW on my 6 cyl supra and it worked. I am planning to swap it on the volvo wagon. Good luck.
 
I was just looking at new in tank pumps as I suspect mine is hashed (getting lean spikes under hard accel with low fuel in tank) and I was on IPD and thought I remembered the stock in tank pump being like $60. But the actual Bosch unit is about $95.

Question though... are any of the DW pumps a straight drop in replacement for the Volvos? On the Evo it was easy peasy... but I feel like when I did my fuel sender, I remembered the pump being an odd size.
 
Another happy DW300 (301???) user here.

It's not a direct swap though. Some minor fiddling is required. More so in my case since I was running larger lines all the way from the tank to the fuel rail. I also rewired the tank sender to use much heavier wiring - the stock wiring to the low-amp in-tank pump is probably not sufficient. I rerouted the wiring that used to go to the external pump back to the tank sender.

As I explained in the first post, I don't have a stock fuel system or the inline pump which is why I was looking for recommendations for aftermarket in tank pumps.

No, they're all a bit longer. I dremeled off about 1/2" when I replaced the faulty sender in my car which already had an aftermarket pump from the previous owner.

You also need to give it it's own relay, the oem pump was a low current / low pressure deal and is fused at only 8 amps I think. Also in my experience, the oem relay doesn't like the higher load either and runs hot. You could, however, power the new in tank pump with the wires of the inline pressure pump that was bypassed: that circuit is fused for a higher current draw.
 
Make sure you get the correct high pressure fittings and hose as well. Last thing you want is for the hose to slip off the nipple at the senderwhen hammering on it.

Yes. I've been browsing this thread http://forums.turbobricks.com/showthread.php?t=274158.

If I had the budget (and knew how) I would love to do the whole thing with AN-6 fittings and move the fuel filter under the hood.
