so once agian im going felpro with arps. if the work is done correctly then i should have no problem with my 350-400 with a felpro and arps? or do you absolutely need a mhg? to be honest, ive had a turbo and a n/a and ive never blown a HG. guess im lucky, im running about 245 on my turbo rite now and its got almost 150k. from what i know its a factory hg and install. i bouight the car about 3 years ago, it was a dealership baby. but it didnt have any mods on it and as far as i know it hasnt had a head gasket replacement.

Basically with a walbro pump it flows more fuel than the stock pump so in turn the stock fuel pressure regulator is designed for a lower amount of flow. Increase the flow and the stock fuel pressure regulator can no longer control it. That is why you need an afpr. Same thing with drilling the jtube, it's designed for stock flow, increase flow and you need to increase the jtube hole size or just bypass it.harley1985;1791289 said:
ya i got all that, what im confused on is the "j tube" wat is that? is it the the steel line that goes into the fuel rail with the banjo bolt on it? honestly i think ill just bypass everything and run a braided line from my stock fuel line to the afpr. on and one more thing, isnt there two stock regulators? one on each side of the fuel rail?
The one closest to the fire wall is the fuel damper..
The J tube is bolted to the block below the intake manifold.

ok I'm kind of new to piston powered cars so bare with me please... I'm not exactly sure what turbo the 89 turbo model came with but mine already has the ct26 so when you say upgraded do you mean modifying it? Also how reliable are those OEM HG because I'm really not looking to keep dealing with HG problems over and over? Also I have messed with fuel pressure regulators before but not on a fuel injected motor is there any difference?

yes they come with stock ct26. he means upgrading the stock turbo. anyhow. about the jtube. i did some handy dandy research and i think i will just go ahead and bypass the jtube, they also sell these block off plates for like 15 dollars. dont see any real reason to get it since you wont see it anyways. on the other hand, does anyone know where to get the bosch 12v relay for the 12v fuel pump mod?
